Correlation and path analysis in sunflower

Abstract

Fifty-one inbreds and three checks of sunflower were laid in a randomized complete block design following recommended package of practices. Correlation studies revealed that seed yield was positively and significantly associated with seed volume weight, hull percentage, percent autogamy, days to 50 percent flowering and oil yield. Oil content was positively associated with plant height, number of leaves per plant, seed volume weight, hull percentage, head diameter, percent autogamy, days to 50 percent flowering, 100-seed weight, seed yield and oil yield. Path coefficient analysis for seed yield at phenotypic level showed that the direct effect was maximum for oil yield followed by 100-seed weight. The maximum indirect effect for seed yield was minimum through oil yield, while it was through yield per plant for oil. © 2002, by Walter de Gruyter Berlin/Boston. All rights reserved.
