【摘要】 采用高稳系数法(HSC),对2009年河南省粳稻联合区试中的4个杂交粳稻新品种(系)进行了高产稳产性综合分析。结果表明,焦杂粳1号是聚合了高产稳产基因的优良杂交粳稻新品种(系);新粳优1号的丰产性较好,具有一定的稳产性,适应范围较窄,环境的变化对其产量有一定的影响;X65003稳产性较好,具有较高的丰产性,适应性广,对环境和栽培条件的要求不严格;9优418(CK)适应范围较窄,对环境因素变化反应较敏感,产量变异性较大,在生产推广中要注意区域示范,选用适宜栽培区域,加强栽培及环境因子的调控等。更多还原

【Abstract】 Using high stability coefficient (HSC), in 2009 in Henan Province, high and stable yield of 4 new hybrid japonica rice varieties (lines) were comprehensive analyzed in japonica rice combined area trial. The results showed that the variety of JIAO ZA JING 1 was an excellent new varieties(lines) with high and stable yield hybrid japonica rice genes; The high yield feature of the variety of XIN JING YOU 1 priority was better with a certain yield, adaptation narrower, changes in the environment to a certain extent for their production; X65003 stable yield was better with high yielding ability, adaptability, and cultivation conditions on the environment was not strictly required; 9 You 418 (CK) adapted to a narrower range and more sensitive response to changes in environmental factors , had greater variability in production, therefore ,promoting the production model need to pay attention to the region, selection of suitable cultivation area, cultivation and environmental factors to strengthen the regulation and so on.更多还原
