四川穗状核桃优良单株坚果综合性状评价研究

Research on Evaluation of Comprehensive Characters of Nuts from Superior Individuals in Sichuan

  • 摘要: 为进一步发掘四川核桃的特异种质资源,在前期穗状核桃种质资源调查的基础之上,应用主成分分析和核桃坚果品质评分,通过对穗状核桃坚果三径值、单果重、核仁重、出仁率、核壳厚、粗脂肪和粗蛋白等指标的综合分析。结果表明:(1)主成分1~3的累计方差贡献率为88.49%,确定了3个反映穗状核桃主要性状的主成分及其主成分函数式,计算出各单株的重要主成分值。(2)建立了坚果综合性状评价函数模型,计算出各单株的主成分综合得分,进行综合比较和排序,各单株顺序为SQLG、HSZML、CTYM、PAXH、HSLH、XJPX。(3)筛选出优良单株3个,分别为HSZML、HSLH和SQLG。

     

    Abstract: In order to further explore the specific germplasm resources of walnuts in Sichuan,the indexes were comprehensively analyzed including spicate of walnut three diameter value,single fruit weight,kernel weight,kernel rate,walnut shell thickness,crude fat and crude protein on the basis of the preliminary investigation spicate walnut germplasm resources,by means of principal component analysis and walnut quality score.The results showed that (1) The cumulative variance contribution rate of principal component 1~3 was 88.49%.3 principal components and their principal component functions were identified for the main traits of spicate walnuts.The important principal components of each individual were calculated.(2)The evaluation function model of nut comprehensive characters was established,and the principal component comprehensive score of each individual was calculated.Then the comprehensive comparison and ordination were made.The order of each individual was SQLG,HSZML,CTYM,PAXH,HSLH and XJPX.(3) HSZML,HSLH and SQLG were selected as 3 superior individuals.
