抗青枯病樱桃番茄品种的初步筛选及评价

对28个樱桃番茄品种的田间抗病性、植株类型、单果质量、果色、可溶性固形物含量等主要经济性状进行调查。试验结果表明,感病品种红艳发病最重,发病率为73.67%,其次是红箭、红日和金艳,发病率分别为23.33%、21.67%和20.33%,其他品种发病率都在20%以下;28个品种的果实颜色、大小、口感等差异明显,除黑宝石映泰及黄金蛋可溶性固形物含量在4.10%以下外,其他品种可溶性固形物含量都达5.20%以上。综合分析,筛选出绿天使、粉仙、红娘9号、绿圆、格丽贝、红椭圆等11个抗青枯病且经济性状优良的樱桃番茄品种,为优质抗青枯病樱桃番茄的选育和推广提供了参考。

Preliminary Screening and Evaluation of Bacterial Wilt-resistance Cherry Tomato Cultivars

This experiment investigated the main economic characteristics of 28 cherry tomato cultivars including disease resistance, plant type, single fruit weight, fruit color, soluble solid content, etc. The results showed that the sensitive cultivar Hongyan had the highest disease incidence, and its disease incidence was 73.67%, followed by Hongjian, Hongri, and Jinyan with the disease incidence of 23.33%, 21.67% and 20.33% respectively, while disease incidence of other tomatoes cultivars were below 20%. 28 cherry tomato cultivars were obvious differences in fruit color, size, taste, etc. Soluble solid content of most tomato cultivars were more than 5.20% besides Heibaoshiyingtai and Huangjingdan, which soluble solid content were blow 4.10%. Other 11 bacterial wilt-resistance cherry tomato cultivars including Lvtianshi, Fenxian, Hongniang No.9, Lvyuan, Gelibei, Hongtuoyuan and so on with excellent economic characteristics were selected out. This study would provide references for cultivar breeding and promotion of cherry tomato.
