摘　　要：通禾857以辽粳5号为母本,通95-74为父本杂交选育而成。两年省区域试验平均产量为8 870.3 kg/hm2,比对照品种秋光增产6.0%。生产试验平均产量8 853.9 kg/hm2,比对照品种秋光增产6.6%。该品种主要优点是高产、抗逆性强,主要缺点是单一氮肥施用量过高,整精米率下降。＇Tonghe 857＇was bred by using＇ Liaojing 5＇as female parent and＇Tong 95-74＇as male parent. The average yield was 8 870.3 kg/hm^2 in two years provincial regional test, which was 6% higher than that of the control. The average yield was 8 853.9 kg/hm^2 in production test, which was 6.6% higher than that of the control ＇ Qiuguang＇. Advantages of this variety are high yield and high tolerant.
