Abstract:
Using 65 species of walnuts as materials，the walnut economic characters of statistics and application of Shannon-Weaver index estimation of different sources of quantitative trait diversity，i.e.H′=-ΣPilnPi，Pi refered to the first I type accounted for the proportion.Finally the application of X±1S proposed standard economic traits in breeding in Yunnan.Through the analysis of Yunnan walnuts economic traits，and a theoretical basis was provided for the promotion of Yunnan walnut breeding and the promotion of good varieties.The results showed that the average genetic diversity index of numerical characters was 4.159，and the main long production areas of Zhaotong(2.977)，Lijiang(2.557)and Dali(2.212) higher diversity index，and Baoshan(1.927)，Qujing(1.384) less.Future breeding kernel color to yellow and white，white，yellow，nucleolus was full，the diaphragm was a papery；per nut weight more than 10 g，average of three kinds of diameters was greater than or equal to 3.2 cm，the shell thickness was less than or equal to 1.1 mm，the oil rate was more than 67%，and the protein rate was more than 15%.The starting point of Yunnan walnut varieties was higher，new standards of breeding should had a certain starting point.
