ABSTRACT
The present experiment was undertaken on one hundred and fifty safflower germplasm lines and five checks which were evaluated for yield and yield related component and their direct and indirect contribution towards yields. Analysis of variance and mean performance for seed yield and its components revealed significant differences among all the germplasm lines for all characters there by indicating presence of variability in genotypes. Seed yield exhibited highly positive significant correlation with number of effective capitula per plant and number of secondary branches per plant. Path analysis studies revealed that highest direct effect on seed yield per plant was exhibited by the character, number of effective capitula per plant (0.413) followed by days to maturity (0.353) and number of secondary branches per plant (0.096). The maximum indirect positive effect on seed yield was exhibited by days to 50 per cent flowering through days to maturity (0.325), number of effective capitula per plant (0.189) indicating the importance of depict selection for these characters.
