Abstract: 6 single and three-way crosses produced by 3 inbred lines, which formed a three-way cross Zhengsan No. 3, were evaluated for grain yield and plant traits. The results showed that the differences of the grain yield were not significant neither among the single crosses nor among the three-way crosses. This indicated that all the 3 inbred lines possessed high combining ability, which ditermined the appraising grain yield of Zhengsan No. 3.

Key words: Corn, Three-way cross, High grain yield, Genetic diversity
