<p class="Style">Production of common bean (<em>Phaseolus vulgaris</em> L.) is often limited by the low soil fertility (LF). Identification of common bean genotypes adapted to LF may be a feasible strategy to overcome the poor plant growth and production in NP-deficient soils. Eight bean genotypes samples/derived from International Center for Tropical Agriculture (CIAT) and three local common bean cultivars were eval­uated in low soil fertility (LF) and recommended fertilizers (RF) at three locations representing high (Mashwarah), medium (Shaban) and low (Al-Qaidah) rainy seasons at Southern Highland Region (SHR), Ibb, Yemen in 2011, 2012 and 2013 following a completely randomized block design, arranged as split plot with either (LF) or (RF) as the main plots and the genotypes as sub plots. Three replications were used. The LF plots was absolute control, it did not receive any fertilizer (LF) and in (RF) plots, it received only 34.5 kg N and 92 kg P<sub>2</sub>O<sub>5</sub> kg. The common bean genotypes varied in phenotypic, nutrient efficiency traits and low fertility tolerant indices. The genotypes G2381B, MIB-156, BFB-140, BFB-141 performed favorably under both (RF and LF) environments. These genotypes were associated with higher values of pod number/plant, seed number/plant and 100 seed weight and leaf area, root nodules mass, shoot mass and root mass, shoot mass, physiological, nutrients and recovery efficiency and geometric mean percent (GMP), mean percent (MP) and susceptible tolerant index (STI) and low values of agronomy efficiency, percent of reduction (PR), low fertility susceptible index (LFSI) and tolerant (TOL). The results also showed that high and significant positive correlation of low fertility yield (LFY) and recommended fertility yield (RFY) with seed number/plant and 100 seed weight, NP recovery and use efficiency, geometric mean percent (GMP), mean percent (MP) and susceptible tolerant index (STI) under LF or RF. These correlations indicates that direction selection for yield under LF or RF would result into improved LF tolerant genotypes. Using phenotypic, nutrient efficiency traits, low fertility tolerant indices and stability indices criteria, only G2381B, MIB-156, BFB-140, BFB-143 and BFB-144 showed high average of yields, with <em>b</em>-value of 1.00 and a very low standard deviation (s<sup>2</sup>d) approaching zero, low ecovalence value (W) and highly significant coefficient of determination (r<sup>2</sup>). However, the regression coefficients indicating stability (<em>b</em>’s) and residuals were highly correlated with slopes (r = 0.943; P &lt; 0.001) and coefficient of determination (r = 0.711; P &lt; 0.001) and equivalent value (r = 0.809; P &lt; 0.001), respectively. Thus the data collected from three locations x three years can be used to select low fertility tolerant (or ‘stable’) genotypes. Such low fertility tolerant genotypes would be better suited for poor farmers in the SHR-Ibb and other similar production regions in Yemen.</p>

Plant landraces represent a repository of a gene pool, local adaptation of their domestic species, and thereby are considered a great source of genetic variations. Such genetic variation can be helpful to mitigate the current and future food challenges. A total of 183 common bean accessions including three commercial varieties collected from 19 Turkish provinces were grown to record their morpho-agronomic variations and to evaluate the best performing accessions under multi-environmental conditions. Plant height, days to maturity, pods weight, seed length, and 100-seed weight were used to evaluate the best performing accessions under different environmental conditions. A wide range of variations for traits like days to maturity (99–161), plant height (21–168.7 cm), seed length (7.41–16.4 mm), seeds per plant (17.8–254.4), and 100-seeds weight (24.97–73.8 g) were observed and can be useful for breeding purposes. The analytic results derived from the first three eigenvectors suggested that plant height, plant weight, 100-seed weight, and days to flowering were biologically significant bean traits. Seed yield per plant was positively and significantly correlated with plant weight and pods weight. Genotype × environment biplot discriminated the studied common bean accessions based on their plant height and growth habit. Plant height, days to maturity, seed width, and first pod height were found highly heritable traits and were least affected by environmental forces. Among 19 provinces, accessions of Bilecik showed maximum pods per plant, seed yield per plant and 100-seed weight, while Erzincan and Sivas provinces reflected the prevalence of bushy and early maturing accessions. Information provided herein comprehensively explored the occurrence of genotypic variations which can be used for the development of candidate varieties responding to breeder, farmer, and consumer preferences.

SUMMARYTo develop an effective breeding programme for rainfed production of the common bean (Phaseolus vulgaris L.), the inheritance of seed yield under such conditions should be understood, preferably considering the effects of environment to account for site or season specificity. Thus, heritability, expected and realized gain from selection, and combining ability were evaluated for a nine-parent diallel of common bean without reciprocals but including parents, at two locations each in Mexico and Colombia, using the F2 and F3 population bulks. Heritability estimated from regressions of F3 on F2 ranged from 0·09 ± 0·18 (S.E.) to 0·75±0·25 for seed yield, from 0·26±009 to 0·34±009 for days to maturity and from0·57±004 to 0·80±004 for 100-seed weight. Expected gain from selection in the F2 was estimated as a percentage of the population mean, selecting the upper 20% of the populations. Expected gain in seed yield ranged from 1·8 to 8·4% in Mexico and from 6·5 to 28·1% in Colombia. Realized gains in seed yield in the F3 were 0·4–7·4% in Mexico and 2·9–15·7% in Colombia. Realized gain values for days to maturity were < 2·2%, and for 100-seed weight > 13·4%. General combining ability (GCA) mean squares (estimated using Griffing's Method 2, Model 1) were significant (P <0·01) and larger than those for specific combining ability (SCA) for all traits at all locations. The parents from the Mexican highlands tended to have a positive GCA effect for yield in Mexico but negative values in Colombia, whereas parents adapted to mid-elevation tropical environments showed the opposite tendency. However, all significant GCA values of breeding line V8025 were positive in both countries.

One of the significant challenges of common bean breeding is developing cultivars with high yields under drought conditions. The present study attempted to map quantitative trait loci (QTLs) and identify molecular markers that are linked to drought tolerance in the common bean. We evaluated 160 recombinant inbred lines (RILs), derived from the cross between the carioca cultivars IAPAR 81 (drought tolerant) and LP97-28 (susceptible to drought). In 2014 and 2015, two experiments were conducted (DS—drought stress, and NS—no drought stress). In the DS experiment, water suppression was performed at the flowering stages R5 to R6. The results of our experiments showed that drought conditions play an essential role in reducing most of the traits that were evaluated. RILs under drought conditions reduced the grain yield by 62.03% and 24% in 2014 and 2015, respectively. We identified 15 quantitative trait loci distributed on the chromosomes Pv01, Pv02, Pv03, Pv07, Pv08, Pv09, Pv10, and Pv11, related to grain yield, seed yield per day, 100-seed weight, number of pods per plant, plant height, number of days for flowering, and number of days to maturity. The characteristics of seed yield per day, 100-seed weight, and number of days to maturity showed that QTLs colocalized on Pv07. Identifying QTLs that are linked to drought tolerance in the RIL population IAPAR 81 × LP97-28 is of particular importance for common bean breeding programs seeking to improve carioca beans that are cultivated in regions with drought conditions, such as Brazil.

SUMMARYA diallel crossing system involving two Pinto and two Kidney common bean (Phaseolus vulgaris L.) cultivars was evaluated in the field. Pin toes were significantly different from the Kidneys in seed yield and numbers of pods and seeds per plant and 100·seed weight. All the traits showed statistical significance among crosses and in comparisons involving parental v. cross means. Heterosis values were large and significant for yield, numbers of pods and seeds per plant, number of seeds per pod and number of days from planting to flowering. The ratio of general to specific combining ability mean squares was low for yield, numbers of pods and seeds per plant and high for 100·seed weight and number of days to flowering. Significant reciprocal effects were found for seed yield and number of seeds per plant, but this effect was completely absent for 100·seed weight.

Selection for seed yield (visual in the F2, visual and plot yield from the F3 to F5, and yield tests in F6) was carried out in two crosses of common bean (Phaseolus vulgaris L.) in high and low soil fertility environments at CIAT-Quilichao, Colombia. Parents were small-seeded and tolerant to low soil phosphorus, possessed indeterminate bush growth habit, and belonged to lowland tropical gene pools of Middle America. The mean yield of selected lines from low (LFS) and high (HFS) soil fertility environments was significantly higher than the mean of the parents in both crosses when tested in high fertility (HF) but not in low fertility (LF). The highest yielding LFS and HFS lines from A 286 × (G 5059 × A 80) and the LFS line from A 286 × ICA Pijao outyielded the best check cultivar, Carioca, in HF. No line yielded significantly more than A 286, the best parent used in both crosses. The mean effect of fertilizer levels on selection for seed yield was nonsignificant. Lines selected under two environments showed similar but average response and high stability of performance under variable environments. Low soil fertility accelerated maturity and reduced 100-seed weight and seed yield.Key words: Phaseolus vulgaris, bean (small-seeded common), selection for yield, soil fertility, Middle American gene pools, regression coefficient

A field experiment was conducted at Nyankpala, near Tamale, Ghana, during the 2014 cropping season and continued during 2015, to investigate one year residual effects of indigenous organic materials (biochar, groundnut shell, rice husk and rice straw) on the growth and yield of maize. It was a 4×3×3 factorial experiment consisting of 4 organic materials at 3 levels (2.5, 5 and 7.5 t ha-1 on dry matter basis) and 3 nitrogen (N) levels (0, 45 and 90 kg/ha N) laid out in a Randomized Complete Block Design with four replications. The study revealed that integrated management of one year residuals of the organic materials with inorganic N supported increased plant height and grain yield, and moderated time of flowering to promote production of maize variety “Wang Dataa”. Application of 7.5 t/ha biochar + 45 kg/ha N, similarly 5 t/ha biochar + 90 kg/ha N supported tallest crop of 200 cm, whilst early flowering ranged 47 to 50 days with 2.5 t/ha biochar + 90 kg N/ha, 5 t/ha biochar + 45 kg N/ha, 7.5 t/ha biochar+ 90 kg N/ha, 2.5 t/ha groundnut shell + 90 kg N/ha and 7.5 t/ha rice straw + 45 kg N/ha. Grain yield was maximised with 7.5 t/ha biochar + 90 kg N/ha, 5 t/ha groundnut shell + 45 kg N/ha, 7.5 t/ha groundnut shell + 90 kg N/ha and 7.5 t/ha rice husk + 90 kg N/ha in the range of 3000 - 3600 kg/ha. The results also showed strongly that either residual nutrients and other plant growth conditions obtained from the organic materials or application N determined LAI, height of cob attachment, cob length, cob weight, 100 seed weight and stover biomass. Residual conditions provided by 7.5 t/ha of biochar gave the highest LAI. The more increased height of cob attachment ranged from 90 to 100 cm, provided by as low as 2.5 t/ha of biochar. Best cob length of 15 to 17 cm was obtained from 2.5 t/ha biochar and 5 t/ha groundnut shell. Cob weight under residual organic materials was in the range of 125 to 165 g/cob with 5 t/ha biochar or groundnut shell and 7.5 t/ha rice straw adequate to maximize the trait. Residual organic materials impacted on 100 seed weight with 5 t/ha of biochar and 7.5 t/ha groundnut shell impacted largest grain size of 25.5g. Stover weight was both highly significantly determined by residual effects of organic materials and N. Application of 5 t/ha biochar or 5 t/ha groundnut shell or 7.5 t/ha rice husk was adequate for highest stover weight. In this study, application of 45 kg N/ha was overwhelmingly sufficient to optimize leaf area index, height of cob attachment, cob length, cob weight, 100 seed weight and stover weight. Pearson correlation coefficients of grain yield with other traits exhibited robust relationships signifying strong impact of integrated soil fertility management of one year residual organic materials and N on maize production in the Guinea savannah. Grain yield prediction indicated treatments were best fitted in polynomials with 7.5 t/ha biochar + 90 kg N/ha for optimum grain yield.

Thirteen common bean (Phaseolus vulgaris) accessions collected from different ecological regions of Jammu and Kashmir were evaluated at four diverse locations during kharief 2009. Significant variation was observed for most of the morphological traits. Estimates of heritability (bs) were high (>60 %) for all the traits except pod length. The expected genetic gain (per cent of mean) was high (>30 %) for days to maturity, number of pods plant-1, number of seeds pod-1, 100-seed weight and seed yield plant-1 while it was moderate (10.0-30.0%) for days to 50 per cent flowering, number of branches plant-1, pod length and protein content. Seed yield plant-1 was observed to have a highly positive and significant correlation both at phenotypic and genotypic levels with number of pods plant-1, pod length, number of seeds pod-1 and 100-seed weight. But negative and significant correlations with days to 50 per cent flowering and days to maturity were estimated from pooled analysis. Classification of accessions led to the formation of two clusters wherein the maximum number 7 accessions were grouped in cluster I and the remaining six were grouped in cluster II. Analysis of traits contributing maximum to the divergence revealed that traits viz., 100-seed weight (37.10%), protein content (15.26%), number of seeds pod-1 (11.28%) and days to maturity (10.14%) to contribute to the divergence in the present experimental material.

Zero (I0), one (I1), and two (I2) rounds of random intermating were made among S1 or S0 families of two interracial populations (GX 8904 and GX 8929) of common bean (Phaseolus vulgaris L.). The resulting S4 families were evaluated for seed yield, 100-seed weight, and number of days to maturity in six environments in Colombia during 1993 and 1994. The experimental design was a partially balanced, 10 × 10 lattice, with three replications. The mean seed yield after I1 increased by 8.9% in population GX 8904 and by 20.1% in GX 8929. No change occurred in seed yield after I2 in either population. The I1 and I2 of GX 8904, on average, were slightly later maturing than the I0. In GX 8929, I2 was later maturing than I0 and I1. The random intermatings did not induce appreciable changes in 100-seed weight in either population. All S4 families in both populations were either small or medium seeded (< 40 g/100 seed weight) and of intermediate to late maturity (> 70 d to maturity).

100 Seed Weight

A total of 80 diverse germplasm accessions of common bean (Phaseolus vulgaris L.) were collected from 31 different locations known for marginal and risk prone farming systems in remote and hilly areas of North-Western Indian Himalayan state of Jammu and Kashmir. The variability was observed in seed color, shape, size and 100- seed weight. Thirteen colors of bean seeds were represented in these 80 accessions with high predominance of red colored seeds. Cuboid, kidney and oval seed shapes observed were represented respectively in 61.25%, 25% and 13.75% of the accessions. There were significant variations in seed length, width and 100-seed weight being highly significant in the later case. All the three seed size classes (small, medium and large according to CIAT categorization) were represented in the collected accessions. 22.5% accessions have 100-seed weight less than 25g, 53.75% accessions have 100-seed weight between 25-40g while 100-seed weight of more than 40g was recorded in 23.75% of the accessions. Highly positive correlations were found between 100-seed weight and seed length and width and between seed length and seed width. The 80 accessions were grouped in three clusters at a coefficient level of 0.3 with largest cluster of 59 accessions followed by a medium cluster with 20 accessions and the least with a single accession. Grid maps generated through DIVA-GIS software indicated that diverse accessions of common bean in terms of seed size and weight can be sourced from the areas falling in Budgam, Shopian and Kulgam districts of the state. Conservation of this remarkable genetic diversity is recommended for future propagation, breeding and the investigation of the genetic relationships.
