本试验选用12个品种参试,比较了各品种的农艺性状、生育期、抗逆性以及经济性状和产量。结果表明,对照品种扬两优6号平均亩产650.70 kg,居第5位;比扬两优6号增产的有甬优4149、春优11、甬优4949、JY12,甬优4949比扬两优6号(对照)增产4.45%;其余参试品种均比扬两优6号减产,其中粳两优5057、武运1152、扬粳306(常)、盐稻12号(常)、南粳9108(常)相比扬两优6号减产极显著,常优12-11相比扬两优6号减产显著,甬优4351比扬两优6号减产不显著。参试品种甬优4949表现为熟期早、产量高、米质优、抗性好。
In this experiment, 12 varieties were selected to test the agronomic traits, growth periods, stress resistance, economic traits and yield of the varieties. The results showed that the average yield of the control variety Yangliangyou 6 was 650.70 kg per mu, ranking No. 5; Yongyou 4149, Chunyou 11, Yongyou 4949, JY12, Yongyou 4949 than Yangliang 2 The yield of the other varieties was increased by 4.45% compared with that of No.6 (control). The yield of the other tested varieties was lower than that of Yangliangyou 6, in which Liangyou 5057, Wuyun 1152, Yangjing 306 (often), Yanami 12 9108 (usual) Compared with Yangliangyou 6, the yield was extremely significant. The yield of Yongyou 12-11 was significantly lower than that of Yangliangyou 6, and the yield reduction of Yongyou 4351 was not significant. The test varieties Yongyou 4949 showed early maturity, high yield, good quality rice and good resistance.
