广西樱桃番茄抗晚疫病材料的筛选

Screening of Cherry Tomatoes With Late Blight Resistance in Guangxi

以26份樱桃番茄为试材,采用田间抗性鉴定与分子标记技术,对樱桃番茄抗晚疫病材料进行检测,研究了不同材料对晚疫病的抗性,以期为抗晚疫病新品种的选育提供参考依据。结果表明:26份田间抗晚疫病材料中,8份含抗晚疫病Ph-3纯合基因,6份含抗晚疫病Ph-3杂合基因,其中TL32、TL101不仅对晚疫病有良好抗性,还含有抗黄化曲叶病毒病Ty-2基因。

The 26 cherry tomato resources were used as materials,the resistance of different materials to late blight was studied by identification in the field combined with molecular marker method in order to provide reference for the breeding of new varieties resistant to late blight.The results showed that 26 tomato materials had the resistance to late blight in the field,8of 26 materials with Ph-3homozygote gene and 6of 26 with Ph-3 heterozygote gene,of which TL32 and TL101had not only the good resistance to late blight,but also the yellow leaf curl virus disease-resistance with Ty-2 gene.
