Genetic analysis of seed morphological traits and its correlations with Grain yield in common bean

This work investigated the genetic control of seed morphological traits and its correlations with grain yield in common bean. Three crossings among bean cultivars with different growth habit and seed characteristics were analyzed. F1 progenies gave origin to F2, RC1P1F1 and RC1P2F1 generations. Rand...
