Elucidation of inheritance of agronomic characters is crucial for the success of plant breeding. The aim of the study is to determine the inheritance of agronomic characters in bean. Two dry bean (Great Northern 59 and Alberto) and one runner bean (Phaseolus coccineus L.) were crossed with six bean lines (PV04035, PV04086, PV04092, PV04145, PV05001 and PV05023) to get 18 hybrid combinations. The F2 populations along with the parents were evaluated in a fully-automated plant breeding greenhouse of Selcuk University in 2019. For seed yield and other agricultural traits, line x tester analysis method was employed to determine general combining ability (GCA) and specific combining ability (SCA), heterosis and heterobeltiosis values, broad and narrow sense heritability and correlations among the traits. For seed yield, non-additive gene effects were important. Heterosis and heterobeltiosis values for seed yield were positive. Compatible parents that can be used in future bean breading programs were determined for the agriculture characters.
