- Abstract
[Objective] The present paper aimed to analyze tomato genetic diversity and reveal the molecular marker loci related to tomato quality traits. [Method] A total of 37 simple sequence repeat (SSR) markers were selected for the polymorphism detection of 30 materials, and based on cluster analysis, the association between marker locus and quality trait by Tassel 3.0 GLM program were analyzed. [Result] A total of 102 allelics variations from 37 SSR markers were detected, and the genetic similarity coefficients of their germplasms ranged from 0. 61 to 0.97. TasseB. 0 general linear model showed that a total of 9 loci were significantly correlated with 5 quality traits. There were genetic diversities among these tomato materials,but the genetic basis was narrow. [Conclusion] The genetic diversities of 30 tomato resources were analyzed by SSR markers. Thirty tomato resources were divided into four groups at the genetic similarity coefficient of 0. 71. There were 9 SSR markers associated with total acid, mature color, ripe fruit color, fruit face furrow and lycopene under GLM program.
