Diallel Analysis of Dry Bean Varieties for Seed Yield and Important Traits for Calcareous Soils

Abstract

Five dry beans (Kınalı, Alberto, Great, Göynük and Özmen) were selected for high calcareous soils tolerance and used as parents in a full diallel method in 2019. F1 and its parents were grown in the experimental field of the Faculty of Agriculture of Selcuk University with high lime content in 2020 with three replications. Variations for seed yield and its component maintenance were detected between parents and F hybrids grown on high calcareous soils, and some crosses were found to outperform their parents. Significant general combination ability (GCA) and special combination ability (SCA) were observed for seed yield per plant and components including plant height, pods per plant, seeds per pod, seeds per plant, hundred seed weight, protein ratio and protein yield per plant. While non-additive gene effects were effective in plant height, pod height, number of seeds per pod, seed yield per plant, protein ratio, and protein yield per plant, it was determined that additive gene effects were effective in other investigated traits. Garrafol was had the highest GCA for seed yield. The "Alberto x Kınalı", "Özmen x G Northern 59", "G Northern 59 x Özmen", Özmen x Kınalı", "Kınalı x Alberto" and "Göynük x Kınalı" crosses exhibited high SCA effects for seed yield per plant. These hybrids are the most promising combination, and it is appropriate to carry out selection processes by evaluating seed yield and yield components together in future generations.
