Abstract: This article studied on a resistant trait(plant damage degree)of upland cotton(G.hirsutum)to spidermites by diallel analysis.Results of combining ability and genetic effect analysis showed that both additive and dominant genetic effects were important to spidermites,and theadditive effects were even more important than the dominant ones.Gene distribution was out ofbalance.Dominant genes were more than recessive ones.It is suggested that the dominant geneshad negative effeets on plant damage degrees,and that the recessive genes had positive effects.The narrow heritability determined in this test was 88.

Key words: Spidermites, Genetic effects, Genetic parameters, Combining ability
