Objective] By combining ability of spring wheat varieties of seven traits, strong adaptability of the parent were selected. [Method] According to Griffing’s the forth design objection of diallel cross and fixity model, combing ability of seven primary agronomic traits in eight spring wheat genotype were analyzed. [Result] The results showed that the two combing ability (GCA and SCA) of seven traits reached highly significance level. The highest GCA effect was 741-2, which had predominantly discrepancy with other genotype. The highest SCA were combination of 834-2 and 741-2, which had predominantly discrepancy with other hybrid combination. [Conclusion] The key of taking advantage of strong offspring was high comprehensive character level. To obtain the offspring of high yield or high quality traits, parents should have at least high combining ability. The parent with high GCA and trait complementation were selected. At the same time GCA and SCA effect were taken effect.
