Cluster analysis of the main agronomic traits of 30 spring wheat strains
Article in 'Chinese Agricultural Science Bulletin'
Abstract
In order to make efficient use of spring wheat germplasm resources and provide material for wheat cultivars breeding, 9 agronomic traits of 30 testing materials were tested for principal component analysis and cluster analysis. The results showed that 7 agronomic traits of effective number of tillers, biological yield, grain yield per plant, grain number per spike, spike length, thousand-grain weight and plant height have a high coefficient of variation over 10%, and they were the main agronomic traits that had an effect on the characteristics of spring wheat. Material could be divided into 3 categories, and the materials in the second category had excellent synthetic performance, the biological yield and grain yield per plant were large,thousand-grain weight and grain number per spike were moderate, so they were good breeding materials with ideal comprehensive characters.
