General combing ability and specific combining ability analysis in sunflower (Helianthus annuns L.) to estimate oil content.

Experiment indicated using Randomized complete block design and data were taken on oil percent in seed of sunflower (Parent and hybrids).

All possible diallel and three way hybrids among seven genotypes of sunflower (Iraq Hower, Kods 3, Flamme 907227, Euro flore, Coban, Royal, Argensum) were consisting in this study.

The results obtained from diallel and three ± way crosses analysis showed that specific combing ability effects were more important than general one which indicated that dominance gene action controlled the inheritance of oil way crosses analysis and study of the relative importance of general and specific combining ability effects, especially from three ± way analysis provide of plant breeder with basic information necessary to choose breeding material and in deciding the order in which they should be combined to get desirable Three ± way hybrids for improving oil content in the seeds of sunflower.
