Abstract: Based on the data of regional wheat （Triticum aestivum L.） test and production test in the south of Huanghuai river from 2015 to 2017, the yield and its components of Xinmai 32 were analyzed by correlation analysis and path analysis. The effects of yield components on yield and the correlation among yield components were researched. The results showed that Xinmai 32 had high and stable yields. The average yield of Xinmai 32 was 8 679.0 kg/hm² and the test site ratio of yield increase was 100.0% in production test. The correlation analysis demonstrated that the effective panicle number, grains per panicle, basic seedlings, maximum tillers and 1000-grain weight were all positively correlated with yield, and the correlations between yield and the number of effective panicles as well as grains per panicle were significant. In partial correlation analysis and path analysis, the correlation degrees with yield were as follows from big to smalleffective panicle number, grain number per panicle, 1000-grain weight, basic seedling, maximum tiller number. The results indicated that effective panicle number and grain number per panicle played a greater role in the yield of Xinmai 32. The high yield cultivation technology of new wheat 32 should increase grain number and 1000-grain weight on the basis of ensuring enough effective number of ears.
