Determination of Combining Ability in Sunflower Parents According to Line X Tester Analysis Method

In this research, which including two cytoplasmic male sterile female (CMS) lines and six recessives branching tester parent (RfRf), 12 hybrids (F 1 ) were obtained by crossing the in Plant Breeding Greenhouse of Field Crops Department 2018-19 winter period. trial was carried out 2019 as four replications. height (cm), head diameter 100 seed weight (g), yield (kg ha -1 ), oil content (%) investigated. Multiple sequence variance analysis, general specific combining abilities, proportional relationships some genetic parameters, heterosis heterobeltiosis values, narrow broad heritability calculated. conclusion, research; their agricultural characteristics determined upon obtaining high sunflower lines. Considering combination abilities parents for F1 generation, R31 identified appropriate plant height; R02 diameter; weight; R61 R80 yield; content. special all found to be significant positive height, RAM-1 X R80, RAM-19 R61, R31, R71 yield.
