Abstract: Abstract:Morphologic diversity of fifty wild rape germplasms collected from Lhasa,Shannan,Rikaze,Chandou and thirty-eight counties in Tibet was analysized and abundant diversity was detected among them. The highest variability coefficient is 72.04% and diversity coefficient is 0.9821. The top six major components represent 85.19% morphologic diversity of wild rape germplasms in Tibet by analysis of major component. There is relativity to some extent as well as a significant diversity among morphologic traits of major components. Through unweighted-pair group method clustering based on morphologic traits, five groups can be classified as the intercept is 1.61, which is related to plant height, number of branches and siliques, and branching framework etc. The results indicate that there is significant genetic variance and abundant diversity about morphologic traits among Tibet wild rape germplams, which helps to unravel genetic basis of Tibet rape germplasm as well as to apply them.
