The present investigation was carried out during Kharif 2016 at ZAHRS, Navile, Shivamogga. The experiment was laid out in split plot design with three replications. There were 24 treatment combinations comprised of three different environments (polyhouse, shadenet and open field) and eight spacing treatments (45 cm x 30 cm, 45 cm x 45 cm, 45 cm x 60 cm, 45 cm x 75 cm, 60 cm x 30 cm, 60 cm x 45 cm, 60 cm x 60 cm, 60 cm x 75 cm). The obtained results showed that all the characters were markedly affected by different environments and spacing. Among different environments significantly higher plant height (325.17cm), number of primary branches (12.46), number of pods per plant (21.66), pod length (70.67 cm), pod girth (3.73 cm), pod weight per plant (31.13 g), yield per plant (458.21 g) and higher pod yield per 1000 m2 (1605.99 kg) were recorded in polyhouse. Among spacing treatments significantly higher number of primary branches (12.91), pods per plant (22.30), pod length (71.73 cm), pod girth (3.94 cm), pod weight per plant (33.11g) and pod yield per plant (547.86 g) were recorded with wider spacing of 60 cm x 75 cm. Highest plant height (294.29 cm) and yield per 1000 m2 (1791.68 kg) were recorded with the closer spacing of 45 cm x 30 cm. The interaction of different environments and spacing were found to be statistically non-significant for all the traits. The evaluation of production economics revealed that growing of Yardlong bean in open condition with 45 cm x 30 cm spacing was most remunerative option with a highest benefit: cost of 3.14.

Abstract Cowpea (Vigna unguiculata) is an important tropical legume crop contributing significantly to food security in tropical regions. The present study was carried out to determine the extent of genetic variation, to estimate character associations, heritability and genetic advance of 25 quantitative traits in 30 genotypes of cultivated Vigna unguiculata from the western highland region of Cameroon. These quantitative traits were selected among cowpea descriptor lists. For all these traits, the analysis of variance showed significant difference among genotypes, highlighting the existence of important genetic divergence among the studied accessions. The highest phenotypic and genotypic coefficient of variation was observed in grain yield, pod yield and 100 seed weight. Genetic advance of these three characters was also the highest. Broad sense heritability was high in general, with 20 traits out of 25 having heritability values greater than 70%. This high heritability indicates little influence of the environment on these characters in cowpea. The highest heritability was recorded for 100 seed weight (98.15%) and the lowest for shoot weight (41.38%). At 0.05 probability level, grain yield correlated significantly with 21 out of the 24 other quantitative traits. Among others, grain yield correlated positively and significantly with 100 seed weight, number of pods per plant, number of branches per plant, number of nodes per plant, plant height, plant width, pod length, pod width, seed length, seed width and number of seeds per pod. These positive correlations between grain yield and many other traits indicate that a selection program based on any of these traits will result in increasing yield. Cluster analysis using UPGMA method revealed five distinct clusters. Genotypes named KEBCP025, KEB-CP006, KEB-CP098, KEB-CP070, and more importantly KEB-CP054 and KEB-CP004, were grouped in a single cluster and were characterized by a significantly higher grain yield, pod yield, number of pods per plant, number of seed per pod, plant height, pod length and pod width compared to other clusters. Accessions KEB-CP036 and KEB-CP031 produced significantly more important fresh biomass. These genotypes could be used as parents in genetic improvement programs aiming to increase yield and fresh biomass in cowpea.

Field irrigation experiments were conducted to assess the varietal performance and correlation of pod yield and yield attributes under irrigation at the Teaching and Research Farm, University of Maiduguri, Nigeria, during 2015 and 2016 dry seasons. The results revealed that the most outstanding for fresh pod yield per plant were okra cultivar Kwadag Y’ar gagure Salkade and, Kwadam in descending order with yield ranging from 580.38-622.67g, while the composite cultivar had the lowest value of pod yield of 428.62g over the two years. The highest mean values for number of pods per plant and number of primary branches per plant were observed for Salkade and Y’ar gagure, respectively. Highest fresh pod length and fresh pod diameter were also exhibited for Salkade and Kwadag, respectively. Genotypic coefficient of variation was higher than the phenotypic variation for all the yield contributing characters. Days to 50% flowering were positive and highly significance difference associated with plant height, number of pods per plant and fresh weight per pod. Path coefficient analysis showed that number of pods per plant exhibited positive and direct effects on pod yield across years. Indirect effect of other yield components through this character also contributed mainly towards pod yield. Therefore, plant height, days to 50% flowering, number of pods per plant, pod length, pod diameter, number of primary branches per plant and fresh weight per pod could be considered for selection and improvement for high pod yielding varieties in okra.

A total of 32 genotypes collected from different geographical areas evaluated at one site to determine the genetic variability. Considerable diversity was found in different traits of horticultural importance. Principal component analysis showed more than 84 % of total multivariate variation for important traits in different genotypes. Pod yield, pod length,10 pods weight and pods per plant were found to be major traits contributing towards principal component-I. Similarly, seeds per pod, secondary branches/plant, pod length were main positive contributing traits towards second component. Ten pod weight, pod width were positively contributing component towards principal component third. Pods per plant and shelling percentage were main traits contributing to principal component-IV, where as plant height, pod length and pod width were major positively contributing traits towards principal component -V. PS-1100, Meethi Phali, PB-87 and FC-1 were most divergent genotypes. On the basis of cluster mean of single linkage cluster analysis, Custer-I was best for number of primary branches and shelling percentage, Cluster -II for plant height,10 pods weight and pod yield per plant, cluster-III for number of pods /plants and cluster IV for pod length. Selection of genotypes from divergent clusters and components having more than one positive traits for hybridization programme may lead to improvement in yield and quality of pea.

Studies on genetic variability, correlation and path coefficient analysis were carried out with 38 accessions of cowpea (Vigna unguiculata L. Walp.) evaluated in two environments i. e. kharif 2013 (E1) and kharif 2014 (E2) at Research field of NBPGR, Regional Station Jodhpur, India. Analysis of variance revealed significant differences among the genotypes for all the traits. Genotypic coefficient of variation was highest for number of clusters per plant followed by number of pods per plant in both the environments. High broad sense heritability along with high genetic advance for seed yield per plant, 100 seed weight, pod length, number of pods per plant, peduncle length, number of clusters per plant, number of branches per plant and plant height indicated the presence of additive gene effects for these traits in cowpea. In both the environments seed yield per plant was positively correlated with 100 seed weight, pod length, number of pods per plant, number of clusters per plant, number of branches per plant and plant height. The highest positive direct effect registered by number of branches per plant followed by number of clusters per plant in E1 environment and by number of branches per plant followed by plant height in E2 environment. The traits like 100 seed weight, plant height, number of pods per plant number of clusters per plant and number of branches per plant were identified as selection criteria for obtaining good parental lines in cowpea breeding programmes.

AbstractA study was carried out at the Federal University of Agriculture Abeokuta, Nigeria to determine the gene action underlying the inheritance of important agronomic traits as well as the general combining ability (GCA) and specific combining ability (SCA) of the parents and hybrids, respectively. Ten hybrids were developed by crossing five lines to two testers. The hybrids and parents were evaluated on the field in a randomised complete block design replicated three times, and data were collected on days to 50% flowering, number of branches, stem diameter, plant height, pod length, pod width, pod weight, number of pods and pod yield. The data were subjected to line by tester analysis and results showed substantial variability among the genotypes for some of the characters measured. Days to 50% flowering, number of pods and pod yield were largely under additive gene action while non-additive gene action was more important in the inheritance of plant height. Favourable GCA and SCA effects for days to 50% flowering were observed in NGB00356, NGB00326 and NGB00347 × NGB00326, respectively. The tester NGB00326 had a positive and significant GCA effect for number of pods while the highest positive SCA effect for pod yield was found in NGB00297 × NGB00326. Thus, NGB00356 and NGB00326 could be considered as sources of alleles for development of early maturing while the cross NGB00297 × NGB00326 could be exploited for high yielding okra genotypes.

Groundnut (Arachis hypogaea L.) production in rain fed regions of Africa is mostly affected by intermittent drought of different duration and intensity. Improvement of groundnuts for drought tolerance could increase production in drought prone areas. Therefore, this study aimed at (i) determining the effect of Watering regimes on yield and agronomic traits of exotic Groundnut genotypes and (ii) identifying drought tolerant genotypes as source material for breeding and drought tolerant varieties. Thirty groundnut genotypes were evaluated for drought tolerance under well watered and water stress conditions in the screen house at Sokoine University of Agriculture (SUA), Tanzania. A split plot design with four replications was used whereby the watering regimes were the main plots with varieties planted as subplots Data were recorded on plant height, number of pod/plant and pod yield/plant. Results showed that drought significantly reduced pod yield, number of pods/plant and plant height. Eleven genotypes namely; ICG 2106, ICR 48, ICGS 44, ICG 3053, ICG 11088, ICGV-SM 87003, ICG 12235, ICG 13723, ICGV 02271, ICGV 97182 and ICGV 91114 gave better pod yield and number of pods/plants in water stress conditions and are recommended for use in breeding program as drought tolerant varieties and sources for breeding materials.

An experiment was conducted in 2013 to study the performance of different varieties of garden pea under Akola condition at Department of Horticulture Dr.Punjabrao Deshmukh Krishi Vidhyapeeth, Akola, Maharashtra. Eight varieties were evaluated on black soil in replicated randomized block design and Results were found significant for all characters among these varieties. All varieties exhibited considerable variation in their performance for most of the parameters. Better growth and yield parameters in terms of plant height (cm), number of branches/plant, days to first flowering, number of green pod/plant, green pod weight, green pod length, pod yield/plant, green pod yield per plot and green pod yield per ha were noticed in all varieties. Maximum plant height was observed in Jawahar Matar-2 (72.26 cm) and minimum was in Palam Priya (28.46 cm). In case of number of pods plant-1 was maximum in PB-89 (16.43) followed by Palam Triloki (13.9) and minimum in Jawahar Matar-2 (9.83). Similarly for pod characters, average pod weight, maximum pod weight was recorded in PB-89 (6.12 g) and minimum was recorded in Arka Kartik (3.27g). Green pod yield/plant was highest in PB-89 (87.93 g), Palam Triloki (75.45 g) and Ankur (68.42 g). Whereas, maximum green pod/yield. was recorded in PB-89 (93.12q/ha) followed by Palam Triloki (76.97q/ha). Among all these varieties highest protein and Total Soluble Solid contents was recorded in Palam Triloki variety (23.06% and 17.67% respectively). PB-89, Palam Triloki and Ankur had the highest yields over the others, hence, they are recommended to farmers in semi-arid condition of Vidharba region for cultivation.

Eighteen genotypes of french bean were evaluated for genetic variability and correlation studies for pod yield and its attributing characters. Both GCV and PCV corresponded closely for all the characters indicating low environmental influence. Highest GCV and PCV were recorded for seed weight per pod (145.12 % and 144.87%, respectively). The highest heritability estimate was observed for number of pods per plant (99.71 %). Pod yield per plant was significantly and positively correlated with number of pods per plant, flower per inflorescence, pod set per inflorescence, plant height and number of leaves per plant. Six characters viz., number of pods per plant (0.917), pod girth (0.791), plant height (0.765), flowers per inflorescence (0.529), pod length (0.284) and days to first flowering (0.134) had high and positive direct effect on pod yield. Therefore, plant height, flower per inflorescence and number of pods per plant emerged as the three most important characters influencing pod yield and selection based on these characters may improve the pod yield.
