[Result] The yield of Shenyu 10 was up to 66.3.4 kg/ 667 m^2 and there were extremely significant differences between Shenyu 10 and Xuanhuangdan 5 （CK）. Moreover, it had strong stress resistance. As Jingdan 12, Beiju 0913, Ante 8000, Yunrui 89 and Yayu 78 were planted in the region, their earing should not appear in rainy months. The inciderce of stem rot and ear rot of Yayu 891 was high, so Yayu 891 should not be planted in the region. [Conclusion] Shenyu 10 had a high yield, suffered few diseases and had strong stress resistance, so it can be popularized widely in the region.展开更多
