Abstract:

Broad sense heritability and genetic advance are the important parameters in breeding programs. In this study broad-sense heritability and genetic advance of seed yield and yield components were evaluated in 20 safflower genotypes. This experiment was conducted in randomized complete block design with three replications. Days to flowering, days to maturity, plant height, number of capitol per plant, number of seeds per capitol, main capitol diameter, 1000 seeds weight and seed yield per plant were measured and recorded. Genotypic effect was significant for the studied traits. The results of broad-sense heritability indicated that main capitol diameter, number of seeds per capitol, 1000 seed weight and plant height traits had the highest value. The main capitol diameter and plant height revealed higher values of genetic advance. High genetic advance coupled with heritability was observed for main capitol diameter and plant height traits. Thus selection based on these traits will be useful in safflower breeding program. s Cluster analysis based on characters of main capitol diameter, number of seeds per capitol, 1000 seed weight and plant height suggested that genotypes of Soviet1, IL111, Goldasht and Tajikistan can be considered as genotypes with high broad-sense heritability and genetic advance and so can be used for breeding purposes.
