A study of correlations and path analyses of some traits in sunflower parental lines

The trial in this study was carried out field conditions throughout three years from plots where seed production of sunflower parental lines established. Eight genotypes were examined; namely RHA-UK, RHA-ST-59, RHA-SES-IMI, RHA-SNRF, RHA-E-ANN-65, RHA-RU-3, RHA-CDN, and RHA-N-M-1. All the examined are components best hybrids developed by Institute Field Vegetable Crops, Novi Sad, Serbia. Relationships between yield eight different traits studied - oil protein content, germination, 1000-seed weight, head diameter, number branches leaves plant height. same analyses for comparison content. A highly significant positive correlation determined height branches; leaves; diameter; yield; diameter germination Path analysis indicated highest direct effect on (0.439**). had a (0.260*). In indirect effects yield, thirteen determined. content showed that high (0.800** -0.847**). existence nine cases.
