Correlation and path analysis of flower diameter with other quantitative characters in standard cut chrysanthemum
摘要
Abstract
The flower diameter and 11 quantitative traits of 27 cultivars of standard cut chrysanthemum were investigated, and an analysis of genetic correlation, correlative heritability and path analysis were conducted. The results indicated: the heritability of broad sense was relatively high for the 12 characters, being all higher than 70%. The flower diameter was in highly significant positive cor relation with the length of the first round ray florets and the length of the second round ray florets, and in significant positive correlation with the width of the second round ray florets;the correlative heritability of the length of the first round ray florets and the length of the second round ray florets related to the flower diameter were higher, respectively, and were close to the heritability of the flower diameter. The efficiency of correlation selection of these two traits would not be much lower than the direct selection of the flower diameter. It is,therefore,concluded that selection should be made for longer and greater number of ray florets,less number of tubular disk florets and higher plant height in selecting excellent standard cut chrysanthemum varieties.关键词
