There were significant differences among 49 cultivars of faba beans (Vicia faba L.) for percent seed crude fibre, seed coat thickness, 1,000-seed weight and seed protein content; 1,000-seed weight was negatively correlated with seed crude fibre (r = −0.52) and positively correlated with seed coat thickness (r = 0.66). Step-wise multiple regression analysis showed that seed coat thickness could provide a partial prediction of seed crude fibre.

Seed Protein Concentration

A recurrent selection method for use in faba bean (Vicia faba) was evaluated over a 10-yr period. The method consists of growing superior lines in open-pollinated random mating nurseries (RMN), selecting heavily podded plants from these lines, evaluating the offspring for yield and seed protein concentration, and replacing inferior lines in the RMN with selections deemed superior. Two types of RMN were established, one for yield (RMY) and the other for both yield and seed protein content (RMP). The criterion for entry of a line into the RMY was a seed yield in the top 3 % of a yield trial while entry into the RMP required a line to be in the top 5% for seed yield and 3% for protein content. A positive increase in seed yield of the selected lines from both RMNs was found over time, but no increase in seed protein content was noted.Key words: Vicia faba, recurrent selection, breeding method, faba bean

A field experiment was conducted at the Agriculture Faculty Farm of Sebha University during the 2007/2008 and 2008/2009 winter seasons to study the agronomic performance of seven pea genotypes with different sowing dates in sandy soil. The experiment was laid out in a randomized complete block design (RCBD) using a split-plot arrangement with three replicates. The five sowing dates (30 October, 15 November, 30 November, 15 December and 30 December) were assigned to the main plots, while the seven pea genotypes (Ambassador, Pollon, MG130256, G22765-2c, 89-P-109-11, No. 252, Victory Freezer and Master B) were allocated to the sub-plots. The sowing dates had a significant effect on all the studied traits except seed protein content in both seasons. Early sowing (15 November) was better than the other sowing dates for all the traits except 100-seed weight. There were significant differences between the pea genotypes for all the traits in the two growing seasons. The Victory Freezer genotype surpassed the other genotypes for all traits except number of branches plant-1 in the second season, 100-seed weight and seed protein content. The highest values for number of branches plant−1 in the second season and for seed protein content were obtained for the G22765-2c genotype, while the maximum values of 100-seed weight were recorded for the MG130256 genotype. A significant interaction between sowing dates and pea genotypes was detected for the length of the period from emergence to initial flowering, number of pods plant−1, seed yield plant−1 and seed yield ha-1 in both seasons. The longest period from emergence to initial flowering was obtained for the Victory Freezer pea variety sown on 30 November, while the highest values of pods plant−1, seed yield plant−1 and seed yield ha−1 were gained by sowing the Victory Freezer pea genotype on 15 November.

Small fababeans (Vicia faba L.) were tested at one location for 2 yr at six seed rates (60–260 kg/ha) and two row spacings (15 and 30 cm). Results indicate that narrow spacing outyields wide spacing at all seed rates, the average advantage being 18.9 q/ha and 5.0 q/ha for 1971 and 1972, respectively. Seed yield increased with seed rate; highest yields were obtained at a seed rate of 260 kg/ha and 15 cm spacing. Treatments had no significant effects on 1,000-seed weight hectoliter weight, or protein content. Yield component analysis revealed that the number of pods per plant decreased with increased seed rates, but weight per pod was not affected. It is concluded that seed yield is a direct function of the number of mature pods per unit area.

Growing Conditions

Several common cultivars of faba beans (Vicia faba L.), grown under similar environmental conditions, had similar concentrations of condensed tannin. The average percent tannins in the testae of eight cultivars was 4.3 ± 0.2 SEM. Storage and growing conditions, however, appeared to have an influence on the concentration of condensed tannin. Assays of condensed tannins from a diverse group of cultivars resulted in the identification of three cultivars of Vicia faba that were tannin-free. These cultivars, all of which produce flowers, testae and hilums that are white in color, are also deficient in those compounds responsible for the formation of a dark-colored polymeric complex when exposed to oxygen. Tannin-free and tannin-containing faba bean cultivars also differed with regard to spectrophotometric properties and elution patterns following Sephadex LH-20 chromatography. The development of suitable cultivars of faba beans that are tannin-free and do not contain the compounds that are responsible for seed coat darkening would likely enhance their nutritional and organoleptic properties.

Abstract Pea is one of the most important grain legume crops in temperate regions worldwide. Improving pea yield is a critical breeding target. Nine inter-connected pea recombinant inbred line populations were evaluated in nine environments at INRAE Dijon, France and genotyped using the GenoPea 13.2 K SNP array. Each population has been evaluated in two to four environments. A multi-population Quantitative Trait Loci (QTL) analysis for seed weight per plant (SW), seed number per plant (SN), thousand seed weight (TSW) and seed protein content (SPC) was done. QTL were then projected on the multi-population consensus map and a meta-analysis of QTL was performed. This analysis identified 17 QTL for SW, 16 QTL for SN, 35 QTL for TSW and 21 QTL for SPC, shedding light on trait relationships. These QTL were resolved into 27 metaQTL. Some of them showed small confidence intervals of less than 2 cM encompassing less than one hundred underlying candidate genes. The precision of metaQTL and the potential candidate genes reported in this study enable their use for marker-assisted selection and provide a foundation towards map-based identification of causal polymorphisms.

Kernel Protein

The most important criterion for introducing new confectionary sunflower hybrids into production is high protein yield. In the breeding process it is important to identify traits which could be used as selection criteria for increased kernel protein content. Increase of kernel protein content results in increased protein yield. This research was conducted during three vegetation seasons on 22 NS high-protein two-line confectionary sunflower hybrids produced within the breeding program at IFVCNS, Novi Sad, Serbia. Strong and very strong correlations were found among the largest number of examined traits. Based on the analysis of simple correlation coefficients, strong negative correlation was determined between kernel protein content and kernel ratio (-0.516*). A weak negative interdependence was determined between head diameter, seed protein content, and kernel protein content. Positive but weak correlation was determined between kernel protein content and thickness of seed, length of seed, width of seed, and 1000 seed weight. Path coefficient analysis for kernel protein content at phenotypic level showed that the thickness of seed had a strong positive direct effect on kernel protein content (DE=382*). Kernel ratio and width of seed had a very strong direct negative effect on kernel protein content (DE=-0.990**; DE=0.600**). A weak direct positive effect of head diameter, seed protein content and length of seed was established, whereas 1000 seed weight had a weak direct negative effect on kernel protein content. Path coefficient analysis indicates showed that the thickness of seed has high great influence on kernel protein content, and an important selection criterion for breeding for high protein yield.
