Intercharacter association and path coefficient analysis in sunflower (Helianthusannuus L.)

One hundred ninety six germplasm accessions of sunflower were included in this study which revealed that seed yield had highest correlation with number of filled seeds per plant, followed by seed filling percentage and head diameter. Oil yield was highly and positively correlated with seed yield per plant and number of filled seeds per plant. Number of filled seeds per plant had maximum direct effect on seed yield. Head diameter also had considerable effect on seed yield. The present study brings out the importance of seeds per plant, head diameter and 1000-seed weight for yield improvement.
