| 摘 要： | 分析1992年～2007年审定推广的57个品种在江苏省区域试验产量表现,并研究3种类型粳稻品种产量结构因素与产量相关性。结果表明:中熟中粳稻相关性大小为千粒重>总粒数>结实率>穗数;迟熟中粳稻相关性大小为总粒数>结实率>千粒重>穗数;早熟晚粳稻相关性大小为总粒数>千粒重>穗数>结实率。并针对不同类型粳稻提出高产品种选育的思路和合理产量结构。 |

| Abstract: | The yield performances of 57 rice cultivars in Jiangsu regional test between 1992 and 2007 were analyzed and the correlations between yields and yield components of three types of japonica rices were studied.The results showed that the coefficient order of medium maturing japonica rice was 1000-grain weight>total grains>seed-setting rate>panicles;the coefficient order of late medium maturing japonica rice was total grains>seed-setting rate>1000-grain weight >panicles;and the coefficient order of early late maturing japonica rice was total grains>1000-grain weight>panicles>seed-setting rate.The high-yielding breeding route and rational yield components were pointed out against different types of rices. |
