Abstract

Abstract: The overall levels of phenotypic characteristics of seed and leaf within and among 5 geographic populations were estimated. The results showed that the percentage of variance portion among population was 10.97% while that within population was 41.57%. The range of variation of differentiation coefficient of morphological traits among population was between 11.85% to 28.34%. The mean phenotypic differentiation coefficient (VST) showed that the variation within population (24.26%) was extremely higher than that among populations (75.74%) which revealed that variation within population were more important. Frequency distribution of 7 phenotypic characteristics in Castanea mollissima primarily displayed a normal distribution. Both multiplicity analysis and Shannon information index is suitable for evaluation of phenotypic diversity in Castanea mollissima.

Key words: Chestnut (Castanea mollissima), Phenotypic variation, Frequency
