Abstract
Genetic control of root development in beans was investigated in the parents, F1, backcrosses and F2 obtained from 6 crosses made among 6 lines obtained from an earlier study of efficiency in P utilization. One line produced significantly larger and more vigorous roots and a narrower shoot/root ratio than the other 5 lines, both at stress and at adequate levels of P. Quantitative inheritance patterns and transgressive segregation for root dry weights were observed and high broad sense heritability estimates were obtained. Dominance variance was more important than additive variance in 4 families.Keywords
