摘要 继获得普通番茄‘北京早红’与秘鲁番茄杂交种后,本试验着重于对杂种后代的形态、亲和性及抗性表现的观察,杂种的多数性状为双亲中的显性性状或双亲的中间型,但也表现了一些奇异性状,如果实的颜色和花序的形状与排列通过株间的“杂交”克服了杂种的高度自交不亲和性,从而顺利得到杂种的自交后代;杂种各世代均高抗TMV 0株系和1株系,并有部分选系抗TMV 1·2株系,由此判断秘鲁番茄亲本可能具有TM^a_2基因;用南京地区CMV厥叶株系和强株系分别接种,各世代表现部分抗病或耐病。 2200 interspecific F1 hybrid plants between L. esculentum ( cultivas Beijing Zaohong) as pistal parent and L. peruvianum ( the accession 8 of PI 128657) were obtained with the means of embryo culture. Among the 1295 F1 hybrid plants observed, 287 plants shew normal in flowering, fruit-setting and seed-developing, the rest set only a few fruits with no seeds inside due to the abnormality in chromo-some numbers ( 2n = 48-96 ) . Many characters of the F1 hybrid were intermidiate to those of its parents such as the shape and size of leaves, growing habit, and size of fruits; but the novel variations also appeared in the F1 hybrid and its progenies, for instance, the color of the F1 fruits and the shape and arrangement of inflorescene in F2 generation. The interspecific self-incompatibility was overcome with the natu-ral 'intercrossing' between F1 plants, meanwhile, the forced self-polli-nation did not result in fruit-setting. The backcrossing between the hybrids and both parents in the reciprocal combinations shew the high incompatibility. All lines of the F1 hybrids and its progenies were highly resistant to strain 0 and strain 1 of TMV respectively, The F2 generation had only tolerance (55.6%) to strain 1·2 of TMV while some lines of F3 generation shew resistance, which indicates that the accession 8 of L. peruviatnum ( PI128657 ) possibly possesses TM_(2) ~a gene. The reactions of the F2 to the fern-leaf strain of CMV from Nan-jing region were high resistance (7.5%), resistance (32.5%), tole-rance (42.5%) and susceptibility (17.5%); The inoculating of the strong strain of CMV from Nanjing region made half of the F2 lines show tolerant and another half susceptible;7.5% lines in F3 generation. shew resistant to the same strain.
