Genetic analysis of F2 and transgressive segregants for seed yield in safflower (Carthamus tinctorius L.)
Keywords: Safflower, transgressive segregants
AbstractThe wide range of F2 variability for seed yield, number of capitula per plant and number of seeds per capitulum in 24 crosses of
line x tester set indicated potential of the crosses to throw large number of variable segregants. Maximum number of positive
transgressive segregants was found in TSF-1 x SFS 9920, TSF-1 x SSF 658, TSF-2 x ASD-07-10, Sagarmutyalu x SFS 9920and
Manjira x SSF 698 crosses. F1 per se performance, relative heterosis, D2 and GCA effects of parents were found to be good
indicators for predicting the phenotypic variance and genetic advance for seed yield in F2. Average GCA effects of parents had
moderate degree of influence on the mean of 10% top yielding plants in F2.
