Gene Action Analysis In Sunflower (Helianthus Annuusl)

The sunflower pure lines EMB, EUR, L3, L6. L10 and PERE12 were used in a halfdiallel mating system to assess the genetics of the characters: flowering date,plant height, number of leaves per plant, stem diameter, leaf area, head area,number of seeds per head, fertility percent, 100 seeds weight, seeds yield perplant and oil and protein percent's utilizing Mather and Jinks theory (1982). Theresults showed that mean square of genotypes, parents, hybrids and parentverse hybrids was highly significant for all characters. Adequacy tests of additivedominance model revealed that data of all characters were partially adequatefor genetic interpretation through most or some adequacy scales used
