茶树种质资源表型遗传多样性分析
Genetic Diversity of Tea Germplasm Resources Based on Phenotypic Characteristics
摘要
Abstract
[Objective] The genetic diversity of tea germplasm resources were studied.[Method] With 16 kinds of local town tea germplasm resources and Fuding Dabai collected from Dongshan town in Suzhou as test materials, biological traits were described.The genetic variation, character correlation and principal component were studied on the 17 kinds of tea germplasm resources based on 7 traits.[ Result] The widest variation was found in leaf size which had a coefficient of variance of 31.49% followed by weight of 100 " a bud and three leaves"(30.80%), length of " a bud and three leaves"(19.74%),leaf length(16.81%), leaf width(15.41%),lateral vein pair number (14.29%), leaf shape(13.30%).It revealed that abundant variation existed in these cultivars.There were significant correlations among those biological traits.The biggest correlation coefficient was 0.92 between leaf length and leaf leaf size, leaf width and leaf area.Three prin-ciple elements were obtained, which contributed over 87.875%of variance.[Conclusion]This study provided reference for the protection, uti-lization and innovation of tea germplasm resources.关键词
