Ten genotypes of sunflower were evaluated in the field following a randomized complete block design with three replications for
plant height, stem diameter at base, inter nodal length, head diameter, number of whorls per head, achene weight per head, 100
achene weight, achene oil and protein contents. Highly significant differences were observed for all the characters in all
genotypes. Characters like plant height, oil contents, protein contents and achene weight per head showed high heritability with
moderate genetic advance.
