摘要
为明确Mi-1-Mi-9基因家族番茄材料对我国南方根结线虫的抗性,采用温室盆栽接种方法对37个番茄品种进行了抗性鉴定。结果明确了8个含有Mi基因的番茄材料中,7个材料对南方根结线虫表现为免疫或高抗。在抗性基因未明确的材料中,6个材料具有南方根结线虫抗性。在16个抗性未知的秘鲁番茄材料中,12个材料抗南方根结线虫。研究证实Mi基因家族番茄对我国南方根结线虫具有优良抗性,为进一步挖掘利用Mi家族基因提供了重要依据。
To clarify the tomato resistant with Mi family gene against Meloidogyne incognita Racel, 37 tomato materials were evaluated in greenhouse with artificial inoculated nematodes method. Seven varieties out of 8 with Mi gene were immune or high resistant to M. incognita. And 6 varieties among materials with uncertain resistant gene were evaluated as resistant to Meloidogyne incognita. Out of 16 Peru tomato lines with unknown resistant gene, 12 lines were resistant to Meloidogyne incognita. The results showed that tomato varieties with Mi family genes had an excellent resistance against Chinese M. incognita Racel population. This study has provided an important basis for further excavating and utilization of Mi family genes.
