| Abstract: | Based on the through investigation of Chestnut Erlizi genetic resource in Zhen an county, Shaanxi province from 2001 to 2006, 13 superior trees were selected by the methods of preliminary selection and secondary selection. Statistical analysis of 10 traits showed that the yield of single tree, mean yield per area of crow shadow, mean fruit weight, nut count per bur and rate of yielded nut from bur of the superior trees are higher than those of the superior tree-selection standard, and meanwhile demonstrates obviously the superior-clone characters. |
