泰州地区粳稻新品种比较试验

Comparative Test of New Varieties of Japonica Rice in Taizhou Region

[目的]为改变泰州地区单一品种种植现象,进行优质水稻的引种示范。[方法]以南粳9108为对照,选取长江中下游7种主栽品种进行同田对比试验。根据不同基因型水稻品种在泰州地区的农艺性状及产量,选择适宜当地栽培环境的株型好、抗病性强、适应性广、产量高、米质优的水稻品种。[结果]不同基因型品种间农艺性状和产量差异较大,农艺性状与产量及其构成因子和外观品质指标间呈显著或极显著差异,南粳52、宁3818、宁3908等品种产量较高、经济性状突出,因此建议进行大面积推广种植。[结论]该研究为筛选出适宜泰州地区推广的水稻品种资源提供了一定的科学依据。

[Objective]To change the phenomenon of single variety cropping,and to carry out the introduction and demonstration of high quality rice in Taizhou.[Method]We selected seven rice cultivars from the middle and lower reaches of the Yangtze River.With Nanjing 9108 as the control,comparactive test in the field was carried out.According to the agronomic characters and yield,we selected rice varieties with good plant type,strong disease resistance,wide adaptability,high yield,good rice quality.[Result]There were significant differences in agronomic traits and yield between different genotypes.There were significant or extremely significant differences in agronomic characters,yield and its component factors and appearance quality indicators.Varieties such as Nanjing 52,Ning 3818 and Ning 3908 had relatively good yield and prominent economic characters,so that they were suggested to be planted widely.[Conclusion]This research provided certain scientific basis for the screening of rice variety suitable for Taizhou District.
