      abstract = {In order to screen suitable high hybrid wheat seed  production technology, the split-plot experiment design was  adopted and study was carried out about the effects of the  different row ratios of male and female parents and  application amount of nitrogen fertilizer on hybrid wheat  seed production and its component factors. The results  showed that the seed production increased with the increase  in the number of female parent row. When the row ratio of  male and female parents was 2:6, the seed production was 3  683.8 kg/ha; when the application amount of nitrogen  fertilization was 50 kg/ha, the seed production was 3 649.4  kg/ha; the interaction between the row ratio of male and  female parents and the application amount of nitrogen  fertilizer indicated that when the row ratio of male and  female parents was 2:6 and the application amount of  nitrogen fertilizer was 300 kg/ha, the seed production  reached the highest (4 160.6 kg/ha). The row ratio of male  and female parents and application amount of nitrogen  fertilizer had significant effect on the component factors  of seed production, including the number of grains per  spike, spike weight and setting percentage. When the row  ratio of male and female parents was 2:5, the number of  grains per spike, spike weight and setting percentage were  the highest at 26.7 grains, 1.12 g, and 62.6% respectively;  when application amount of nitrogen fertilizer was 450  kg/ha, the number of grains per spike, spike weight and  setting percentage were the highest at 26.0 grains, 1.08 g,  and 59.2% respectively; the interaction of row ratio of  male and female parents and application amount of nitrogen  fertilizer had significant effect on the number of grains  per spike, spike weight and setting percentage; when the  row ratio of male and female parents was 2:5 and the  application amount of nitrogen fertilizer was 300 kg/ha,  the number of grains per spike, spike weight and setting  percentage were the highest at 29.6 grains, 1.24 g, and  71.6% respectively. Conclusions: the number of grains per  spike is the largest component factor for seed production.  Increasing the number of grains per spike can increase the  seed production. According to the effects of row ratio of  male and female parents and application amount of nitrogen  fertilizer on the component factors of seed production, the  optimal condition was 2:5-2:6 for row ratio of male and  female parents and 300-450 kg/ha for application amount of  nitrogen fertilizer. },
