小麦产量和品质若干性状的相关性

Studies on the corrclativities among some yield and quality characters in wheat.

选用17个小麦品种,进行了24个项目的有关产量和品质特性的测定,对所获数据予以性状的相关性分析,从而揭示性状间的内在联系。结果发现:单株籽粒产量与收获指数呈极显著正相关,与籽粒蛋白质含量呈极显著负相关;籽粒蛋白质含量与湿面筋含量、赖氨酸含量等7项品质指标均呈显著或极显著正相关。

In order to find the correlativities among some yield and quality characters in wheat, on experiment carried out in Zhejiang Academy of Agricultural Sciences during 1986-l987, 17 wheat cultivars' yield and quality, and the correlativities among 24 items were tested. The positive significant correlations were found between yield and harvest index, and between protein content and 7 other quality items in grain. A negative significant correlation was also found between yield and protein content.
