茸毛、Ｔｍ－２ｎｖ重组基因型对病毒病的抗性调查结果表明：重组基因型间的病毒病抗性存在极显著差异，茸毛基因能极显著地降低病毒危害，而Ｔｍ－２ｎｖ各基因型间的病情指数却无显著差异。１９９３年秋季大田生态条件下，番茄病毒病危害潜力达６３．４８％，其中ＣＭＶ、ＴＭＶ分别约占６７．７％和３２．３％。ＣＭＶ和ＴＭＶ危害程度的相对大小是制订Ｔｍ－２ｎｖ和茸毛基因综合利用方案的重要依据，当ＣＭＶ占主导地位时，主要以茸毛基因利用为宜
The results of resistance to virus disease in the hairy and Tm-2nv recombinant genotypes showed that there was a significant difference in viral disease resistance between the recombinant genotypes, and the hairy genes could significantly reduce the virus damage. However, among the genotypes of Tm-2nv The disease index was no significant difference. Under the ecological conditions in the autumn of 1993, tomato virus disease potential reached 63.48%, of which CMV and TMV accounted for 67.7% and 32.3% respectively. The relative magnitude of the harm of CMV and TMV is an important basis for formulating the comprehensive utilization program of Tm-2nv and velvet hair. When CMV dominates, the utilization of velvet hair is the most important
