| 摘 要： | 对2005年度辽宁省审定的10个水稻品种农艺性状与产量等资料进行分析,结果表明:千粒重、每穗粒数与产量的关联度最大,通径分析表明:每穗粒数和每穴穗数对产量产生的直接效应较大,因子分析表明:成穗率、每穴穗数、每穗粒数、结实率取得累计贡献率62.37%,表明上述因子是影响产量的决定因子。

| Abstract: | Agronomic traits and yield of 10 rice varieties registered in 2005 in Liaoning Province were analyzed and the results indicated that 1000-grain weight and grains per panicle had the most correlation degree with yield;path analysis showed that grains per panicle and panicles per hill influenced yield directly;factor analysis showed that the accumulative contribution ratio of productive panicle rate,panicles per hill and kernel set to yield was 62.37%,indicating that factors above are the determined ones on yield. |
