The contents of star anise oil in the fruits of 10 Illicium verum superior individuals selected by Yunnan Academy of Forestry were determined by using steam distillation methods.

The plant growth characters, nut shape feature and main nut economic trait for 50 superior plants of Xingshan Juglans Regia were studied.

In order to solve status that traits of economic forest plus trees and elite clones can not be scientifically and reasonably classified because of the difficulty in quantify quality index,the lack of system,relationship and comprehensive on the methods of growth index contrast and synthesis grade.

In order to solve the problems in the measurement of plus trees and clones, the plus trees and clones were classified by using the Fuzzy linear weighting transformation model combined with quantitative and qualitative indexes on the basis of surveying, selecting and clones tested for walnut in Bijie area.
