Abstract
Variability and association studies were conducted in a set of 75 germplasm lines of safflower
received from DOR, Hyderabad. Sufficient variability was present in the germplasm for number
of capitula per plant, number of seeds per capitulum and seed yield (kg/ha). The 100 seed
weight (g) had high heritability coupled with high genetic advance whereas plant height and
number of capitula per plant had high heritability with moderate genetic advance. Number of
capitula per plant and number of seeds per capitulum showed positive significant correlation
whereas, the remaining characters showed significant negative correlation with seed yield.
Number of capitula per plant had maximum direct effect on seed yield and rest of the traits
had negative direct effect on seed yield. Number of capitula per plant and number of seeds
per capitulum were identified as important yield components; hence, selection should be
focused on these traits to improve yield in germplasm lines of safflower.
Key words : Genetic parameters, correlation, path analysis, safflower.
