Correlation and path coefficient analysis for the yield components of safflower germplasm (Carthamus tinctorius L.)
Twenty safflower germplasm lines were evaluated during rabi 2013-14 to determine the relationship among yield and yield components. The genetic parameters like genotypic and phenotypic variability, genotypic and phenotypic coefficient of variation, heritability and genetic advance were studied. Besides these parameters correlation coefficient and path analysis were also studied for seed yield and its component traits in safflower. Significant differences existed among the germplasm lines for all the characters studied. The estimate of broad sense heritability was highest for 100-seed weight. Seed yield/plant exhibited positive and significant correlation with number of seeds/capsule and 100-seed weight. Path coefficient analysis indicated that 100-seed weight exhibited maximum direct effect followed by number of seed/capsule.
