Abstract

F2 and backcross populations of eight crosses among seven parents of different growth habits were studied to determine the genetics of flowering patterns in pigeonpea. Our results confirmed the presence of two independent genes (Dt1-Dt2-) for flowering pattern in pigeonpea. The expression of Dt2 gene controlling semideterminate flowering pattern was completely suppressed in the presence of Dt1 gene controlling indeterminate flowering pattern. Both the genes in homozygous recessive form (dt1dt1dt2dt2) caused determinate flowering pattern.
