本文主要介绍番茄抗病杂交种‘渝抗一号’的选育过程和主要性状。该品种是运用杂交优势利用原理,以‘玛T’（Manapal TM—2nv）作父本,小鸡心等作母本配制组合,经品比、组合力测定筛选出来的最佳组合,再经连续三年的区域性试验、抗病性鉴定及中型生产试验选育而成的一代杂种。属无限生长型。中晚熟,具有生长势强、着果率高、红色大果、商品性好,高抗TMV‘O’株系,丰产等特点,优于生产品种。1984年通过技术鉴定并在生产上推广应用。 This paper mainly introduces the breeding process and main characters of tomato disease-resistant hybrid ’Yukang-1’. The variety is based on the principle of utilization of heterosis, using Manapal TM-2nv as the male parent and chicken heart as the optimal combination selected from the mother-plant combinations selected by the ratio of product to the combinatorial force, Three years of regional trials, disease resistance identification and medium-sized production test breeding a generation of hybrids. Is an unlimited growth type. Medium and late-maturing, with strong growth potential, fruit rate, red fruit, good commercial, high anti-TMV’O ’lines, high yield and other characteristics, better than the production of varieties. In 1984 through the technical appraisal and promotion of production.
