用类番茄茄与番茄属的 9个种进行有性杂交 ,通过人工离体胚培养获得栽培番茄‘粤农二号’×类番茄茄的F1植株。杂种近于不育。用栽培番茄、类番茄茄、野生番茄及(栽培番茄×野生番茄 )与之回交及杂交 ,获得与栽培番茄的回交子一代及与秘鲁番茄、多腺番茄、潘那利番茄、粤农二号×秘鲁番茄F1的杂种 ,但它们的能育性很低。用栽培番茄、野生番茄与它们再回交及杂交 ,未能得到与栽培番茄的二次回交子一代 ,只获得 (粤农二号×类番茄茄 )× (粤农二号×秘鲁番茄 )的F1与秘鲁番茄、多腺番茄的复合杂种。人工苗期接种黄瓜花叶病毒 (CMV)结果表明 ,类番茄茄及其与番茄属的远缘杂种对CMV有较强的抗性。
Nine hybrids of tomato and tomato were sexually crossed, and the F1 plants of cultivated tomato ’Yue nong 2 × tomato’ were obtained by artificial in vitro embryo culture. Hybrid is near infertility. Backcrosses and crosses were made with cultivated tomatoes, tomato plants, wild tomatoes and (cultivated tomatoes × wild tomatoes), and backcrossed generations of cultivated tomatoes and cultivars of cultivars such as Peruvian tomato, Polygamous tomato, Penalty tomato, Cantonese farmer II × Peruvian tomato F1 hybrid, but their fertility is very low. The cultivated tomato and wild tomato were then backcrossed and crossed with each other, and the secondary backcross generation with the cultivated tomato could not be obtained, and only (Yue Nong 2 × Pomodoro ×) × (Yue Nong 2 × Peruvian tomato) F1 hybrid with Peruvian tomato, polygamous tomato. Inoculated with cucumber mosaic virus (CMV) at artificial seedling stage showed that tomato and its distant hybrids with tomato were more resistant to CMV.
