Correlation analysis for seed yield and its component traits in sunflower

Abstract

Fifty sunflower genotypes were laid in a randomized block design following all recommended package of practices. Correlation studies revealed that seed yield per plant was positively and significantly associated with 100-seed weight, seed volume weight, head diameter, duration of reproductive phase and oil content. Oil content was positively associated with duration of reproductive phase, head diameter and seed volume weight, whereas the association between hull content and oil content was found to be highly significant and negative.
