“…As given in Table 4, seed yield/plant was positively and significantly correlated with each of pod length, number of pods/plant, number of seeds/pod, number of seeds/plant as well as 100-seed weight during the two seasons. In this respect, positive and significant association was recorded between seed yield with each of number of pods/plant, number of seeds/pod and 100-seed weight by many others (Ulukran et al, 2003;Ahmed et al, 2013;Sharifi, 2014;Verma et al, 2015;Jalal et al, 2016;Hamza, 2017;Hamza and Khalifa, 2017;Kumar et al, 2017;Tekalign et al, 2017). Also, Mitiku and Wolde (2015) showed that, number of seeds/pod with seed yield/plant was positively and significantly correlated.…”

843) for earliness, yield, yield attributes and quality characteristics through mean performance, correlation coefficient, path coefficient and molecular markers of RAPD-PCR analysis. The experimental design was a randomized complete block design in four replications. Results indicated highly significant differences among the ten faba bean cultivars for earliness characters (days to first flower, days to 50% flowering and days to fruiting), yield and its attributes (plant height, number of branches/plant, number of fruiting nodes/plant, pod length, number of pods/node, number of pods/plant, number of seeds/pod, number of seeds/plant, 100-seed weight and seed yield/ plant) as well as quality characters (protein and carbohydrate contents) in the two seasons. The new cultivars were earlier than the old once during the two seasons. The new faba bean cultivar Nubaria 1 gave the highest productivity however Sakha 4 recorded the highest value of protein and carbohydrate contents in the two seasons. Seed yield/plant appeared positive and significant correlation with each of pod length, number of pods/plant, number of seeds/ pod, number of seeds/plant and 100-seed weight during the two seasons. Whereas, negative and significant correlation was detected between seed yield/plant and each of plant height and number of fruiting nodes/plant in both seasons. Path coefficient analysis showed that number of seeds/plant followed by 100-seed weight had the highest direct effect on seed yield/plant during the two seasons. Five primers were used for RAPD analysis to determine genetic variability among the ten cultivars of faba bean, and produced 32 bands, 21 of them were polymorphic with 65.6% polymorphism. Four positive bands markers were recorded in faba bean cultivar Giza 3 in two primes (C06 and C19), and two positive band markers in faba bean cultivar Giza 40 in the two primers (B09 and C19). While, one negative band marker in Giza 429 and one positive marker in Giza 843 were generated by primer (C19).

“…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.
