Abstract: Based on the survey data in 82 fields of direct-seeded late Japonica rice at Jiaxing in North Zhejiang, statistically analyzed by means of multivariate regression analysis and path-coefficient analysis, the ways for high yield of direct-seeded late Japonica rice in North Zhejiang Province were studied. The results showed that the effective panicle per hm2, filled grain number per panicle and 1000-grain weight had positive effects on yield, and filled grain number per panicle was the largest and the second was the effective panicle per hm2. For obtaining higher yield of direct-seeded late Japonica rice, it is necessary to develop the filled grain number per panicle and increase the 1000-grain weight by improving the grain-filling quality on the basis of obtaining a suitable effective panicle number which will insure high yield. It was suggested that the yield component for 9500 kg/hm2 yield of the direct-seeded late Japonica rice in North Zhejiang Province might be 125×104/hm2 of planting seedling, 630×104/hm2 of peak seedling, 450×104/hm2 of effective panicle, above100 grains of total grain number per panicle, 90-95 grains of filled grain per panicle and 26 g of 1000-grain weight under the present practice.
