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。
Following the discovery of the hybrid tomato variety ’Beijing Hong Hong’ and Peruvian tomato, this experiment focused on the morphological, affinity and resistance performance of the offspring of hybrids. Most of the characters of the hybrid were the dominant traits in the parents or the parents Intermediate, but also showed some strange traits, if the actual color and inflorescence shape and arrangement of cross-strain “hybridization” to overcome the hybrids of a high degree of self-incompatibility, which successfully obtained self-hybrid hybrids; hybrids All generations were highly resistant to TMV 0 strain and 1 strain, and some of the selected lines were resistant to TMV 1 · 2 lines, thus the parents of Peruvian tomato might have TM ~ a 2 gene. The strains were inoculated separately and all the generations showed resistance or disease resistance.
