Abstract

The study was conducted at the Horticulture Research Institute, Agriculture Research Center, Egypt, from 2022 to 2023 to study the inheritance of some economic characters in dry beans. Three dry bean cultivars, namely DB 435, Giza 6, and Nebraska, were chosen to produce two crosses and their reciprocals. The direct crosses were DB 435 × Giza 6 and DB 435 × Nebraska. Seeds of the P1, P2, F1, F1r, and F2 populations from the two crosses were planted on March 2, 2023, using a randomized complete block design. The results indicated that over-dominance or complete dominance was estimated for the high parent in all studied traits. Positive heterosis over the better parent was detected for most of the studied traits, suggesting the presence of additive gene action affecting these traits. High or moderate broad-sense heritability was recorded for all traits, indicating that these characteristics could be used as suitable criteria for selection and improvement in dry bean breeding programs, except for the trait number of seeds per pod, which showed low heritability. Results indicated that selection for dry yield per plant could be substituted by the number of pods per plant and average seed weight traits.
