同异分析法在食用向日葵种质资源评价中的应用

Abstract

Abstract: In this study, the multiple traits of 21 confectionary sunflower＇s inbred lines were comprehensively evaluated by using similarity-difference analysis method. The results showed that 8 of the 21 confeetionary sunflower＇s inbred lines behaved well and could be used as the key inbred lines for the further research. Seven of the 21 confectionary sunflower＇s inbred lines performed commonly and could be kept in the field for observation. Six of the 21 confectionary sunflower＇s inbred lines with poor performance were eliminated from the breeding program. It was indicated that the similarity-difference analysis method was comprehensive and objective in the germplasm resources evaluation of sunflower＇s inbred lines.
