“…Otherwise, Giza-843, Misr-3, Sakha-1, Sakha-3, and Wadi-1 had lower levels of resistance and were susceptible to chocolate spot infection. Similarly, Bouhassan et al 11 ; Beyene et al 13 ; Tekalign, et al 39 ; Waly, et al 40 , and Heiba, et al 41 depicted highly significant variations in chocolate spot resistance evaluated in faba bean genotypes. Sowing date considerably affects available climate variables that significantly impact chocolate spot resistance.…”

Chocolate spot and heat stress devastatingly impact the production of faba bean, particularly under prevailing climatic changes and rising drastic environmental conditions. Hence, the adaptability of faba bean performance is a decisive objective of plant breeders to ensure its sustainable production. The present study aimed to evaluate the agronomic performance and stability of diverse eleven faba bean genotypes for yield characters, chocolate spot, and heat stress in eight different growing environments. The faba bean genotypes were evaluated at two sowing dates in two different locations during two growing seasons. The evaluated eleven faba bean genotypes were sown timely in autumn (25 October) and late sowing in early winter (25 November) in Bilbeis and Elkhatara during 2020 and 2021 growing seasons. The results exhibited substantial differences among the evaluated sowing dates, locations, and faba bean genotypes for all studied characters. The genotypes Sakha-3, Nubaria-3, Nubaria-5, Misr-3, and Wadi-1 were able to produce acceptable yield and quality characters under timely sowing in autumn and late sowing in early winter in all tested environments. Moreover, the genotypes Nubaria-3, Nubaria-4, Nubaria-5, Sakha-4, Giza-3, and Triple White exhibited better resistance to chocolate spot. The assessed faba bean genotypes were evaluated under late sowing to expose the plants to high temperature stress at flowering and throughout the anthesis and seed-filling stages. The genotypes Nubaria-5, Nubaria-3, Nubaria-4, Sakha-3, Sakha-4, Wadi-1, and Misr-3 possessed tolerance to heat stress more than the other genotypes. Different statistical methods were applied to study the stability of assessed genotypes such as joint regression, Additive Main Effect and Multiplicative Interaction (AMMI) analysis, AMMI stability value, Wricke's and Ecovalence values. The estimated stability parameters were consistent in depicting the stability of the assessed faba bean genotypes. The findings revealed that Sakha-1, Misr-3, Nubaria-4, and Nubaria-5 demonstrated stable and desirable performance across all tested environments. The heatmap was employed to classify the assessed faba bean genotypes into different groups based on agronomic performance, chocolate spot resistance and heat stress tolerance. Nubaria-3, Nubaria-4, Nubaria-5, and Misr-3 had the best performance for agronomic performance, chocolate spot resistance, and heat stress tolerance. The obtained results provide evidence of employing promising faba bean genotypes for improving the stability of agronomic performance, chocolate spot resistance, and heat stress tolerance in breeding programs principally under unprecedented climate fluctuations.

The study included evaluating the performance of three different source cultivars of broad beans (Histal, Fava da orto, and Luz de otono) and estimating genetic and phenotypic variations, heritability, and expected genetic improvement of the yield and its components in one of the fields of the Department of Horticulture and Landscape Engineering - College of Agriculture and Forestry - University of Mosul during autumn season 2019. - 2020, under the influence of some cultivation treatments, which are two treatments, the first is bacillus biofertilizer at two concentrations (no spraying and 1 ml L1) and the second is spraying with boron at three concentrations (no boron and 30 and 60 mg L-1) within a completely randomized block design with three replicates. The analysis of variance revealed that the cultivars had statistically significant mean squares at the 1% probability level for various traits including plant height, biological yield, number of days for 50% of the plants to flower, average pod weight, pod length, weight of green seeds, average weight of 100 seeds, yield of green pods, and total yield of green pods. The cultivars exhibited statistical significance at the 5% probability level for both the number of branches and the percentage of pods set. Significant genetic variance values were observed for all traits, except for the number of green seeds. Similarly, significant environmental and phenotypic variance values were observed for all traits being investigated. The heritability of most traits was high, with values ranging from 0.124 for the number of green seeds to 0.992 for plant height. The anticipated genetic enhancement values, expressed as a percentage of the mean trait, were notably high for the following traits: plant height, biological yield, number of days to 50% flowering, number of flowers, average pod weight, average weight of 100 seeds, green pod yield, and overall yield. Complete set of green pods.

“…Previous studies have reported the economic effects of heterosis on yield components, with hybrids having higher heterosis values than the parent for yield components and maturity stage in faba beans [25]. Additionally, Tekalign et al and Waly et al [38,39] reported significant heterosis in F1, which increased by 40% compared to the parents. Furthermore, the yield quantity and quality of F1 were higher than the mean values of better and mid parents [40].…”

The faba bean (Vicia faba L.) is a major legume crop; thus, it is important to apply various biometrical techniques to develop the most efficient breeding procedures to face biotic and abiotic stressors. During the four consecutive winter seasons of 2017–2021, five populations of five faba bean hybrids were studied at Sakha agricultural research station in Egypt. Five basic generations, including two parents (P1 and P2) and the first, second, and third generations, were studied. This analysis found significant variations between generations in all attributes studied in all crosses (P1, P2, F1, F2, and F3). Sakha 4 was the earliest parent (138 days) based on the maturity date, whereas Giza 40 had the most significant number of pods and seeds per plant (25.68–78.94), and Giza 716 had the tallest plant height (124.00 cm). Giza 843 and Sakha 4 had the highest seed yield per plant values (62.84 g and 61.77 g). The data demonstrated highly substantial heterosis in the favorable direction over mid and better parents for all features, except for the number of branches in Cross 3 (Giza 40 × Giza 843) over mid and better parents and a maturity date in Cross 1 over mid parents. Contrarily, opposite-direction dominance and dominance × dominance effects increased narrow-sense heredity. Broad-sense heritability values for all examined characteristics were high in all crosses, ranging from 90.24% to 97.67%. In both Crosses 5 (Giza 716 × Qahera 4) and 3, genetic advance through selection ranged from 1.73% at the maturity date to 95.12% for seed yield per plant. Cross 3 (Giza 40 × Giza 843) had the greatest number of branches, pods, and seeds per plant. In conclusion, this study advances our understanding of employing faba beans in breeding programs.
