Generation mean analysis to determine genetic components in safflower (Carthamus tinctorius L.)

Study of genes action to improvement of morphological traits is very important. For this purpose, an experiment was conducted in ۲۰۱۳-۲۰۱۵ in the researching farm in Isfahan, Iran using the generations of the crosses between two pure lines (KIR۱۰۱۵× Ac-Sunset) based on randomized complete block design with three replications. The results of generation mean analysis showed that for plant biomass and for plant seed yield, number of head per plant two parameters m and [a] were the best fitted. Three parameters m, [a] and [d] was shown to be the best fit of the observed to the expected generation means for ۱۰۰ seed weight. Yield traits such as plant seed yield, number of head per plant were controlled by additive effects, which suggest scope for breeding and selection for improved safflower.
