103份番茄种质资源精简化栽培下遗传多样性分析及综合评价
Genetic diversity analysis and comprehensive evaluation of 103 tomato germplasm resources in streamlined cultivation
摘要
Abstract
[Objective]Streamlined cultivation of tomato is a new type of cultivation management method that does not require scaffolding,pruning,and branching during plant growth.This project aims to screen germplasm resources suitable for streamlined cultivation of tomatoes and cultivate new tomato varieties that are suitable for cultivation methods.[Methods]103 limited growth tomato germplasm resources were taken as ex-perimental materials to carry out streamlined cultivation management of open ground tomatoes.By measuring 13 quality traits and 11 quantitative traits,genetic diversity analysis,correlation analysis,cluster analysis,principal component analysis,and membership function analysis were conducted,and finally a comprehensive evaluation was conducted.[Results]The results showed that the coefficient of variation for 24 personality traits was 6.12%-185.25%;The genetic diversity index H'was 0.132-2.062;Among 276 pairs of trait correlations,there were 28 pairs of traits with significant correlation(P<0.05)and extremely significant cor-relation(P<0.01),respectively;Cluster analysis divided 103 tomato germplasms into 4 groups,among which the third type material had a relatively upright plant type,high fruit uniformity and single plant yield,which could be used as a suitable parent material for streamlined cultivation hybrid combinations.In principal component analysis,13 personality traits were classified into 5 principal components,with a cumulative contri-bution rate of 65.969%;The top 5 materials ranked according to the D were 21CL2597,21CL2577,21CL2571,21CL2631and 21CL2654.[Conclusion]103 germplasm materials have rich genetic diversity in streamlined cultivation,and comprehensive evaluation suggests that 21CL2597,21CL2577,21CL2571,21CL2631 and 21CL2654 are suitable for streamlined cultivation.关键词
