Abstract:
This study reported that researches had been made on the yearling cultivated cuttings of 7 willow species from 16 clone with regard to plant type variability. The weights of leaves, branches and stems at different heights of the trunk were taken as plant type variables. 20 plant type variables with significant genetic diversities had been chosen by means of variance analysis. From sample correlation matrix 4 principal factors had been extracted, of which the first principal factor is the total biomass factor (y1). The second principal factor is the stem type factor (y2). The third principal factor is the tree crown type factor (y3). And the fourth principal factor is the tree crown density factor (y4). Quantitative description of 16 willow clone’s plant types and comparison had been made in accordance with the different score of each factor, and high yielding plant types had been chosen from them.
