1981和1982年,在哈尔滨地区11个点,调查不同栽培方式和不同品种番茄病毒病的发生情况和以含抗 TMV 基因的品种为亲本所获杂种一代抗病性的表现,并对病毒病毒源类型进行鉴定。结果指出,感病程度因不同品种而异,同一品种在不同栽培条件下抗病性也不同。强力米寿(具有抗 TMV 的 Tm-1基因)有一定的抗病性,但在某些条件下发病率很高。以矮黄(具有抗 TMV 的 Tm-2nv 基因)和俄亥俄 MR-9(具有抗TMV 的 Tm-2~a 基因)为亲本的 F_1,田间抗病性显著高于对照品种6613。两年来,先后25批采集病毒标样共250个,在无虫网室内经过生物鉴定和物理抗性测定,指出在哈尔滨地区番茄病毒病的主要毒源类型是烟草花叶病毒(TMV)。研究结果指出,用含 Tm-2nv 和 Tm-2~a 抗病基因的番茄品种与经济性状优良的番茄品种杂交获得抗病性高、经济性状优良的杂种一代或育成新的抗病品种,是解决番茄上烟草花叶病毒的有效途径。
1981 and 1982, 11 points in Harbin were investigated in different cultivation methods and different varieties of tomato virus disease occurrence and resistance to TMV gene-containing hybrid strains of the hybrid generation of the disease resistance performance, and the virus virus source Type of identification. The results showed that the susceptibility varies with different varieties, the same variety in different cultivation conditions are also different disease resistance. Strong Mishou (Tm-1 gene with anti-TMV) has some disease resistance, but in some conditions the incidence is high. F_1 with low yellow (Tm-2nv gene with anti-TMV) and Ohio MR-9 (Tm-2 ~ a gene with anti-TMV) were significantly higher than those of the control variety 6613. In the past two years, 25 batches of virus samples have been collected in succession. After identification and physical resistance testing in non-insect nets, it is pointed out that the main source of tomato virus disease in Harbin is tobacco mosaic virus (TMV). The results showed that hybrids with high Tm-2nv and Tm-2-a resistant genes and tomato varieties with good economic traits could produce hybrids with high disease resistance and economic traits or breeding new resistant varieties Effective Way to Solve Tobacco Mosaic Virus on Tomato.
