摘要:本研究以大别山地区96份川榛种质资源为基础材料,采用概率分级和因子分析的方法,评价了川榛坚果16项数量性状和9项质量性状指标。结果表明:川榛坚果数量性状的变异较为丰富,变异幅度在5.49%~111.18%,其中与产量直接相关的壳仁间隙(111.18%)、果仁质量(32.61%)、坚果质量(32.22%)、出仁率(26.60%)及壳腰厚度(25.46%)性状变异较大。经K-S检验表明,供试性状除了果仁形状指数(P=0.007)和壳仁间隙(P=0.003)2项指标外,其他14项性状指标均符合正态分布。因子分析法提取了坚果大小因素、坚果出仁率因素及坚果饱满度因素,初步构建川榛坚果性状综合评价指标。上述研究为川榛坚果性状的评价、描述和质量等级的建立提供参考依据。
96 accessions of C. kweichowensis H. H. Hu collected from Dabie mountain were investigated for nut traits including 16 quantitative traits and 9 qualitative traits. Both probability classification and factor analysis methods were employed to evaluate the traits. The results showed that the variation of quantitative traits were relatively abundant,ranged from 5. 49 % to 111. 18 %. The quantitative traits relevant to nut yield had obvious variation,including shell kernel clearance( 111. 18 %),kernel quality( 32. 61 %),nut quality( 32. 22 %),kernel mass percentage( 26. 60 %) and shell thickness( 25. 46 %). K-S test showed that 14 nut quantitative traits follow normal distribution with the significance value higher than 0. 05 except for kernel shape index and shell kernel clearance. Factor analysis method extracted nut size factor,nut kernel mass percentage factor and nut plumpness from 16 quantitative traits,which preliminary built comprehensive evaluation index of nut quantitative traits for C.kweichowensis H. H. Hu. The study will provide a reference for evaluation,description and data standardization of nut traits for C. kweichowensis H. H. Hu.
