Abstract: Statistic analysis on the combining ability and other genetic parameters of yield,protein,oil and other traits by Griffing’s method 4 with diallel crossed F1’s data of 3 high protein and 3 high oil parental varieties was made.Both variances of GCA and SCA are significant,but GCA is more important in all agronomic characters except yield and oil content.The correlation between protein and oil is significantly negative.But both of them are weakly correlated with yield.These seemed better for selecting high-yield lines with high content of oil or protein.There are evident heterosis in F1 hybrid of peanut.Most of their traits are inclined to the high parents,and hundrend seed weight,propein and meat content tend to their low parent.

Key words: Peanut(Arachis hypogaea), Protein, Oil, Combining ability, Genetic parameter
