对25年寒地水稻花培育种与同期常规育种统计资料进行了比较分析。经花培入选的产量鉴定新品系的选择效率为16．94％，是同期常规新品东选择效率11．34％的1．49倍；经花培育成的审定品种的选择效率为o93％，是同期常规育成审定品种选择效率o．28％的3．32倍。从花培育成品种的推广种植面积与常规育成品种比较分析，花培育种与常规育种有同样好的选择效果。
A comparative analysis was made on the statistics of 25 years of paddy rice breeding and conventional breeding in the same period. The results showed that the selection efficiency of the new lines identified by flowering was 16.94%, which was 1.49 times higher than the 11.34% selection efficiency of conventional new products in the same period. The selection efficiency of the certified varieties cultivated by flowers was o93% During the same period, the breeders routinely selected varieties for selection. 28% of the 3.32 times. From the popularized cultivars to popularize the planting area compared with the conventional breeding varieties, flower breeding and conventional breeding have the same good selection effect.
