The results of correlation analysis and path analysis showed that the effective panicle number of “Min Mai 0 6” had the greatest effect on the yield, with the net contribution rate of 5 4.90%. The effect of the solid grain number per panicle on the yield was second, and its net contribution rate 1 9.1 2%. The yield structure of “Min Mai 0 6” (3 3 75 ~ 45 0 0kg hm2) was 3 40.8 ± 5 1 .0 hm2 effective panicle, 2 7.2 ± 1.48 seeds per panicle, 43 .6 ± 3 .92g. The results of cultivation experiment showed that the optimum sowing date of “Min Mai 0 6” was mid-to-late of January 1, and the suitable seeding rate was 150.5-175.5 kg hm2. On the basis of applying full-base fertilizer and three-leaf fertilizer Appropriate amount of jointing fertilizer has a significant effect of increasing yield
