Effect of different row ratios of male and female parents on seed yield of 10 you 18 (a hybrid nonglutinous rice variety).

The results from studying effects of different row ratio of male and female parents on seed yield and setting rate of 10 you 18(a hybrid nonglutinous rice variety) showed that the row ratio between 2∶4 and 2∶12 had no significant difference in seed yield but there was significant difference in setting rate between different row ratios,and the setting rate reduced with distance increment between male parent and female parent.The low row ratio with advantage of raising yield of female parent and reducing seed amount of male parent can be used in seed production of 10 you 18.
