多抗番茄砧木的田间筛选

摘要

In this study, we identified naturally-induced bacterial wilt resistance, field root knot nematode resistance of five tomato rootstocks which were bred by Guilin Vegetable Research Institute, and investigated their main economic characters and grafting effects. The results showed that the two rootstock materials TB09-1-3-2 and TB09-2-2-6 had better comprehensive performance, and they could be used as rootstock in tomato production and as the disease-resistant breeding materials of tomato as well.%　　对桂林市蔬菜研究所初步筛选的5份番茄砧木材料进行青枯病自然诱发抗性鉴定、根结线虫抗性田间鉴定、主要经济性状调查以及嫁接效果比较试验。试验结果表明，代号为TB09-1-3-2和TB09-2-2-6的2份试材综合表现突出，满足生产上作为嫁接砧木使用的要求，可作为多抗番茄育种材料使用。
