Abstract:
Phenotypic diversity of walnut germplasm resources were investigated from main characters through variation analysis，clustering analysis and principal component analysis based on 152 superior trees from 6 cities/counties in Qinghai.The results showed that，variation coefficients of many economic indicators，such as fruit weight，nuclear shell thickness，kernel situation，take the kernel were difficult，nucleolus plumpness was in a relative high level.Consequently，those could be considered as reference guides in walnut variety breeding.The variation extent of all walnut characters was the greatest in Xunhua area among all 6 walnut growing areas，where the genetic diversity showed great abundance.In general，the walnut from Jianzha area was ranked first in the 6 walnut areas；the result from cluster analysis showed that the 6 walnut areas could be clustered into 3 classes when the distance was 5.Different geographical location，climate and rainfall conditions leaded to walnut phenotypic variation degree different，richness of genetic diversity.
