    Abstract:

    Factor analyses of 40 capsicum landraces in Hunan were carried out. These varieties were clustered to 7 groups. It was indicated that the numerical taxonomy basically revealed the genetic differences among the varieties. When the characteristic values reached over 75% in their accumulative contribution rates, these main factors' values would represent the genetic characteristics of these traits. Fruit weight, fruit number and plant shape were very important variables influencing the main factors of capsicum varieties. The main factor after Promax rotation could represent more precisely the genetic characteristic of varieties than these after Varimax rotation. Compared with other systematic clustering method, UPGMA would be better for the numerical taxonomy of the capsicum varieties.
