“…The large estimates of dominance effects for biomass, particularly in crosses Aurora/2 × Mélodie/2 and Mélodie/2 × ILB 938/2, indicate the importance of dominance gene effects in the inheritance of productivity in faba bean. This finding is in agreement with earlier reports (Abd El-Zaher, 2016;Farag & Afiah, 2012;Hobbs & Burnett, 1982) in this species. Selection may be delayed to later generations, which may provide an opportunity to further improve yield by e.g.…”

Increasing productivity through improvement of photosynthesis in faba bean breeding programmes requires understanding of the genetic control of photosynthesis‐related traits. Hence, we investigated the gene action of leaf area, gas exchange traits, canopy temperature, chlorophyll content, chlorophyll fluorescence parameters and biomass. We chose inbred lines derived from cultivars 'Aurora' (Sweden) and 'Mélodie' (France) along with an Andean accession, ILB 938, crossed them (Aurora/2 × Mélodie/2, ILB 938/2 × Aurora/2 and Mélodie/2 × ILB 938/2), and prepared the six standard generations for quantitative analysis (P1, P2, F1, F2, B1, and B2). Gene action was complex for each trait, involving additive and dominance gene actions and interactions. Additive gene action was important for SPAD, photosynthetic rate, stomatal conductance and Fv/Fm. Dominance effect was important for biomass production. It is suggested that breeders selecting for productivity can maximize genetic gain by selecting early generations for canopy temperature, SPAD and Fv/Fm, then later generations for biomass. The information on genetics of various contributing traits of photosynthesis will assist plant breeders in choosing an appropriate breeding strategy for enhancing productivity in faba bean.

“…The existence of wide spectrum of heterosis in either direction with expression of high degree of desirable heterosis by some crosses for most of the characters observed in present study is in conformity with the earlier reports for such characters in faba bean. (Alghamdi, 2009;Ibrahim, 2010;Mourad, 2011;Farag and Afiah, 2012;Abd-El rahman et al, 2012;Bakhit and Abdel-Fatah, 2013;Obiadalla-Ali et al, 2013;Zeinab and El-Emam, 2013;El-Banna et al, 2014;Zeinab and Helal, 2014;Ashrei et al, 2014;Bishnoi et al, 2015;2017).…”

“…The heterotic effects in faba bean ranged from significantly positive to significantly negative for different traits depending on the genetic makeup of the parents.

The present investigation was carried out at the Students’ Instructional Farm, Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya to evaluate a line x tester set of 45 hybrids (F1’s) and their 18 parents alongwith two checks for twelve characters. Forty-five crosses were constituted in Rabi, 2016-2017, whereas parents and crosses were evaluated in a yield trial in Rabi 2017-2018, in a randomized complete block design of three replications. Results revealed highly significant variations within parents and F1 genotypes indicating a wide genetic variability for the studied characters and the possibility of genetic improvement using such genetic material of faba bean. Parents, HB 10, HB 50, EC 454751 and EC 301470 showed desirable and significant GCA effects for grain yield per plant and some of the yield contributing traits to emerge as valuable donor parents for hybridization programme. Out of forty-five, eleven crosses emerged with positive and significant SCA effects for grain yield per plant. The high estimates of genotypic and phenotypic coefficient of variation and high heritability in broad sense alongwith high genetic advance in per cent of mean were recorded for number of pods per plant. A wide range of variation in the estimates of heterobeltiosis and standard heterosis in positive and negative direction was observed for grain yield per plant as well as remaining eleven traits. In case of grain yield per plant, heterobeltiosis ranged from -35.75 to 100.74 per cent, standard heterosis varied from -35.10 to 46.30 per cent over SV1 (HFB 1) and from -33.26 to 50.46 per cent over SV2 (Vikrant).

“…According to Food and Agriculture Organization (FAO), presently, it is grown in 58 countries.In Egypt; faba bean (Vicia faba L.) is one of the most important pulse crops. It plays an important role in world agriculture due to the high protein content, its ability to fix atmospheric nitrogen and its capacity to grow and yield well on marginal lands [1,2]. Great efforts have been directed to improve yield level and quality properties in faba bean.…”

“…Superiority of hybrids over the better parent for seed yield and its attributes are associated with the magnitude of heterotic effects in important yield attributes, that is, number of branches per plant, pod setting percentage, number of pods per plant, 100-seed weight, shellout percentage and pod filling percentage. These heterotic effects may range from significantly positive to significantly negative for various traits according to genetic makeup of the parents [3,4,5,2].…”
