摘要
[目的]为选育优良水稻新品种提供参考资料。[方法]采用同异分析法,对12份水稻新品种(系)的综合农艺性状和品质进行综合评价分析,并且讨论了同异分析法在水稻新品种(系)综合评价中的有关问题。[结果]农艺性状和品质性状的综合同一度大于0.8以上的有10个品种,其中大于0.9的有2个品种:武2105、常优02-6。综合评价为"差"的有甬优5号1个品种,占8.3%,"一般"和"好"的有4个品种,占33.3%,"较好"的有5个品种,占41.7%,"优良"的只有武2105和常优02-6两个品种,占16.7%。[结论]同异分析方法在水稻亲本、杂交组合及比较品种区域试验分析中具有广阔的应用前景。
[Objective] The study aimed to provide reference data for breeding new superior rice variety, [Method] By similarity-difference analysis, the comprehensive agronomic characters and quality of 12 new rice varieties （lines） were evaluated anti analyzed comprehensively. And the relative problems about similarity -difference analysis in the comprehensive evaluation of new rice varieties （lines） were discussed. [Result] The integrated identie degrees of agronomic and quality characters of 10 varieties were bigger than 0.8, among which the 2 varieties with the integrated identic degrees bigger than 0.9 were Wu 2105 and Changyou 02-6. One variety with bad comprehensive evaluation was Yongyou 5, accounting for 8.3%. Four varieties with common and good comprehensive evaluation accounted for 33.3%. Five varieties with better comprehensive evaluation accounted for 41.7%. Only 2 varieties with superior comprehensive evaluation were Wu 2105 and Changyou 02-6, accounting for 16.7%. [Conclusion] Similarity-difference analysis had broad application prospect in the analyses on rice parent, cross combination and regionally comparative variety experiment.
