“渝抗二号”、“渝抗三号”是以抗重庆地区番茄主要病毒—烟草花叶病毒(TMV)‘O’株系为重点,运用优势育种原理,选用T_2(含TM-2nv基因)作父本,汉思松、101T_6等作母本配制组合,经品比、组合力测定筛选、区域试验、抗性鉴定、同功酶分析及生产试验选育而成。属早熟、自封顶型,具有生长势强、结果多、红色中大果、商品性好,高抗TMV‘O’株系,丰产等优点,优于生产品种,已在生产上大面积推广应用。 “Yu Kang 2” and “Yu Kang 3” focused on the anti-TMV O line in Chongqing. By using the principle of dominant breeding, T 2 (including TM-2nv gene ) For the male parent, Hanson, 101T_6 and other female parent combination preparation, by the ratio, combination force determination screening, regional testing, resistance identification, isozyme analysis and production test breeding. Is a precocious, self-captive type, with strong growth potential, the result is more, the large red fruit, good commercial, high anti-TMV’O ’lines, high yield, better than the production of varieties, has been widely applied in production .
