Abstract

In order to gain knowledge of genetic diversity of wheat and improve their usage efficiency as germplasm resource. Diversities of agronomic and quality characters were analyzed for 146 foreign wheat germplasm in the field in southern Shanxi Province, basing on the data statistic analysis, principal component and cluster analysis methods. The average coefficient of variance was 10.9%, and the average diversity index was 1.4 with 18 wheat characters. It was-to seed yield, spike length, kernels per spike, spikes per plant, 1000-grain weight, stability time, tensile area, maximum resistance, sedimentation value and development time. Principal component and cluster analysis were used to 31 high-yield germplasm resources. The additive contributing rate of first eight principal components was 92.73%, eight major discriminating characteristics were selected to reflect the comprehensive economic characters and quality characters. According to the genetic distance, 31 germplasm resources were divided into 7 groups. Each group had different characteristics and showed abundant genetic diversity in agronomic and quality characters.
