Impact of biparental mating on genetic variability and path analysis in safflower

V. Rudra Naik, M.G. Bentur, K.G. Parameshwarappa

Abstract


Biparental mating (BIP) attempted in the F2 of a safflower cross A1 x EC-408475-1 revealed that the population had better mean performance than the F3 progenies for all the characters studied. In general, the lower limits of the range decreased for all the characters in the biparental population widening the variability. The variation created on account of biparental mating was found to be heritable as seen from increase in heritability estimates and genetic advance as percent mean. Path coefficient analysis revealed that direct effects in respect of number of seeds/ capitula, 100 seed weight and volume weight  towards seed yield was higher in BIP.
