辽宁地区水稻品质性状特性及品种聚类分析

Characteristics of Rice Quality and Cluster Analysis of Species in Liaoning Province

为提高辽宁水稻品质性状改良进程,以全省2006年区域试验的12个水稻新品系为试材,对水稻品质性状进行相关分析及品种聚类分析。结果表明,供试品种性状相对稳定,碾磨品质较好,整体提高难度大;品质性状间的相互关系极为复杂;类群间品质性状总体差异相对较小,可以通过改进外观品质性状达到改善碾磨品质和蒸煮食用品质性状的目的。

In order to quicken the improvement process of rice quality and character in Liaoning province,correlation analysis and cluster analysis were made on rice quality and characters using the 12 new rice varieties in the regional experiments in 2006 as the test materials. The result shows that the characters of the test varieties are relatively stable,the milling quality is fine and it is difficult to make overall improvement,that the correlations between quality and characters are very complex while the difference between quality and characters among monoids is relatively slight and the purpose to improve the milling quality and cooking and eating quality traits can be achieved by improving the appearance quality traits.
