Abstract

Abstract:

In order to provide data basis and theory reference for the protection,development and utilization of Yanshan chestnut resources. The diversity of 28 leaf phenotypic traits（five quality traits and 23 quantitative traits）of 149 germplasm resources from 11 Yanshan populations was studied. The results showed that：（1）There were significant differences（P < 0.01）in 28 leaves quantitative traits within the population,and only four quantitative traits had significant or extremely significant differences among populations. There were no significant differences in five quality traits among populations,indicated that the phenotypic variation of Yanshan chestnut leaves was at a low level among populations,and there were abundant variations within populations.（2）The average of phenotypic differentiation coefficient among populations were 7.80%,which was much less than that within populations（92.20%）. It showed that the variation within populations was the main source of variation.（3）The average variation coefficient（CV）and the Shannon-Wiener index（H'）of leave phenotypic traits were 15.91% and 1.24,respectively. Among the five quality traits,the variation coefficient（CV）and Shannon-Wiener index（H'）of leaf shape were the highest（34.44%,0.82）,the variation coefficient（CV）and Shannon-Wiener index（H'）of leaf margin character were the lowest（0,0）. The variation coefficient（CV）of 23 quantitative traits ranged from 4.52%（Stoma width）to 28.32%（sawtooth depth）,and the Shannon-Wiener index（H'）ranged from 1.97（leaf length/width）to 2.09（Petiole length）. The average Shannon-Wiener index（H'）of physiological,appearance and anatomical structure were 2.05,2.04 and 2.04,respectively,and the average variation coefficient（CV）from high to low was 12.61%（appearance）> 12.53%（physiological）> 10.29%（anatomical structure）.（4）The nine quantitative traits（leaf thickness,thickness of palisade tissue,leaf area,leaf length/width,stoma length,stoma density,leaf mass per area,the angle between sawtooth and leaf margin and sawtooth depth）contained abundant genetic information,which could be used as typical traits for phenotypic diversity analysis of Yanshan chestnut leaves.（5）Based on nine typical leaf traits,149 chestnut resources were clustered into five groups at the Euclidean distance of five.
