2019年高邮市粳稻新品种应用安全性测试

Application Safety Test of New Geng Rice Varieties in Gaoyou City in 2019

2019年在高邮市汤庄镇汉留村19组开展水稻新品种应用安全性测试,对其适应性、丰产性、抗逆性、生育期及主要农艺性状进行全面考察分析,结果显示:武运粳32号产量位次列第1位,达696.0 kg/667 m2,高产稳产性最为理想;扬农稻1号、盐粳15号、扬辐粳9号、苏垦118产量位次分别列第2~5位,分别为688.5、682.5、675.5、671.5 kg/667 m2,具有较高的产量潜力;淮稻5号作为高邮市当家品种,产量660.0 kg/667 m2,居第7位;南粳9108产量620.0 kg/667 m2,居第12位。武运粳32号、扬农稻1号、盐粳15号、扬辐粳9号、苏垦118有待下一年扩大示范种植继续考察。

In 2019,a field trial was carried out to assess the application safety of 14 new japonica rice varieties in Group 19 of Hanliu Village,Tangzhuang Town,Gaoyou City.These varieties were investigated and analyzed comprehensively with respect to adaptability,yielding ability,stress tolerance,growth period,and main agronomic traits.The results showed that the yield of the variety“Wuyunjing 32”reached 696.0 kg/667 m2,which ranked first among the 14 tested varieties,exhibiting the greatest yielding ability and yield stability.Besides,the yields of the varieties“Yangnongdao 1”,“Yanjing 15”,“Yangyujing 9”,and“Suken 118”ranked second(688.5 kg/667 m2),third(682.5 kg/667 m2),fourth(675.5 kg/667 m2),and fifth(671.5 kg/667 m2),respectively;thus,they have high yielding capacity.On the other hand,“Huaidao 5”,the main japonica rice variety planted in Gaoyou,ranked seventh in yield(660.0 kg/667 m2),and the yield of the variety“Nanjing 9108”ranked twelfth(620.0 kg/667 m2).Given the high yields of“Wuyunjing 32”,“Yangnong 1”,“Yanjing 15”,“Yangyujing 9”,and“Suken 118”attained in this trial,it is necessary to conduct large-scale demonstration plantings next year for further assessing their yielding capacity and yield stability.
