Six wheat varieties with different protein content in grain were crossed by Griffing's diallel method I to investigate their combining abilities in F1 to F3 generation. The GCA and SCA variations were significant at 0. 01 level, suggested that the protein content was controlled by additive and nonadditive effects. The ratio of GCAMs/SCAMs was also significant in F1 to F3 generation, suggested the additive effect was principal. The interactions of generation by GCA and SCA were significant but reletively small in magnitude compared with GCA and SCA. The GCA could be approximately estimated from the mean value of parents.
