Abstract:
In order to study the genetic relationship and use resourses rationally in breeding,systemic clustering analysis was conducted based on 10 agronomic traits of 84 germplasm resourses in Brassica napus.The results showed that 84 cultivars (lines)were devided into 4 classes.Class Ⅱ included 75 cultivars (lines)and was devided into 2 subclasses again.Subclass Ⅱ -1 and Ⅱ -2 were devided into 3 and 4 groups respectively.4 classes had quite different agronomic traits.Growth period of subclass Ⅱ -2 was 197.4 days only longer than class Ⅳ, but it′s yield per plant was highest. Specific materials such as long pod,big grain,early material and big density of pod were found in resoures.
