Özet
Fresh bean is the most important pulse crop which are sold fresh, canned, and frozen. The genetic variability and association studies help in selection which would increase the yield potential of fresh bean. The experiment was conducted using randomized block design in 2021 at Konya with 25 genotypes (5 parents and 20 F2 Population). General and special combination abilities, heterosis and heterobeltiosis values, broad and narrow sense heritability, as well as the relationships between the investigated traits, were determined in the parent and F2 hybrids suitable for the diallel analysis method. It was found that there is an additive gene effect in the inheritance of the seed yield trait, and non-additive gene effect in the inheritance of the protein ratio trait. It was determined that the heritability in the narrow sense was low for the seed yield and protein ratio traits. It was also determined that non-additive gene effects were effective in the inheritance of seed yield and protein ratio traits. In F2 generation, the mean heterosis value determined in terms of seed yield was positive and the mean heterobeltiosis value was negative. As a result of this research, a sufficient level of genetic variation was determined in the population, considering the agronomic characteristics examined. Determination of suitable parents and hybrids for green bean breeding in terms of sustainability of calcareous soils, agronomic characteristics and inheritance of these parents and hybrids were determined.
