优质多抗樱桃番茄亲本资源筛选

Screening of high quality multi-resistance cherry tomato parental resources

  • 摘要: 【目的】 综合评价樱桃番茄高代自交系,筛选优质、多抗的亲本材料,为樱桃番茄育种提供种质资源。 【方法】 以42份樱桃番茄品种高代自交系为材料,采用因子分析法分析和评价12个性状(果实横径、果实纵径、果肉厚、单果重、可溶性固形物、总酸、固酸比、可溶性糖、果糖、蔗糖、苹果酸和VC含量),并采用PARMS方法检测其抗性基因。 【结果】 综合排名前三名依次是599号、596号和601号,三个番茄材料果实果形均好,可溶性固形物、可溶性糖、果糖、VC含量较高,抗性相对较差,可作为优质樱桃番茄亲本资源。580号综合排名第4,品质较好,且含有5个抗性基因,可作为优质多抗樱桃番茄亲本资源。531号品质综合排名为24,但其抗性基因较多,含有6个纯抗基因,可利用其较好的抗性进行抗病樱桃番茄的育种。 【结论】 筛选出优质樱桃番茄3份,优质抗病樱桃番茄材料1份,抗病樱桃番茄1份,可作为培育不同类型的樱桃番茄亲本资源。

     

    Abstract: 【Objective】 To comprehensively evaluate the high generation inbred lines of cherry tomato and screen the high quality and multi-resistant parental materials in the hope of providing germplasm resources for cherry tomato breeding. 【Methods】 42 high generation inbred lines of cherry tomato were used as materials to analyze and evaluate 12 traits (fruit transverse diameter, fruit longitudinal length, flesh thickness, fruit weight per fruit, soluble solid content, total acid content, solid acid ratio, soluble sugar content, fructose content, sucrose content, malic acid content, vitamin C content) by factor analysis. The resistance genes were detected by PARMS method. 【Results】 The top three in the overall ranking were No. 599, No. 596 and No. 601. The three fruits had good shape, high soluble solid content, high soluble sugar, fructose and vitamin C content, and poor resistance, so they could be used as high-quality cherry tomato parent resources. No. 580 ranked 4th overall, with good quality and 5 resistance genes, which could be used as high-quality multi-resistance cherry tomato parental resources. The overall quality ranking of No. 531 was 24, but it had more resistance genes and contained 6 pure resistance genes, which could be used for breeding resistant cherry tomato. 【Conclusion】 Three high-quality cherry tomatoes, one high-quality disease-resistant cherry tomato material and one disease-resistant cherry tomato are selected, which can be used as parent resources for cultivating cherry tomatoes with different characteristics.
