GENE ACTION ANALYSIS IN SUNFLOWER (HELIANTHUS ANNUUSL)

Abstract

The sunflower pure lines EMB, EUR, L3, L6. L10 and PERE12 were used in a half
diallel 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 per
plant and oil and protein percent's utilizing Mather and Jinks theory (1982). The
results showed that mean square of genotypes, parents, hybrids and parent
verse hybrids was highly significant for all characters. Adequacy tests of additive
dominance model revealed that data of all characters were partially adequate
for genetic interpretation through most or some adequacy scales used.
