摘要: 为选育适宜保护地栽培的番茄新品种,根据地理远缘杂交优势和基因组合原理,有目的地由荷兰、美国、日本等国引进杂交种,在保护地中多代自交分离,结合添加杂交、人工接种抗病性鉴定、配合力测定筛选的技术方法选育不同抗病,生长势强,果实性状好的优良自交系892-43、882-32、892-54、882-7。杂交组合892-43×892-54和882-32×882-7经配合力测定、多年多点试验、区域试验和生产示范均表现优良,最终分别定名为‘中杂9号’和‘中杂8号’。‘中杂8号’和‘中杂9号’的突出优点是:(1)复合抗病性强:高抗ToMV,中抗CMV,抗叶霉病和枯萎病;(2)耐低温弱光;(3)果实品质好,畸型果、裂果率低,品质好;(4)丰产性好。[结论]‘中杂9号’和‘中杂8号’是国内首次育成的含cf5基因,同时抗ToMV、中抗CMV、抗枯萎病的保护地新品种。

Abstract: New tomato varieties were selected and bred for protected cultivation. Zhongza 8 and Zhongza 9 were developed on the basis of combination of wide cross and gene combination. Firstly, some hybrid tomato seeds were introduced from US, the Netherlands and Japan. And then several elite inbred lines including 892-43,882-32,892-54,882-7 were screened by self-cross segregation combined with cross breeding, artificial inoculation and combining ability tests in the protected field. Among them, two hybrid combinations 892-43× 892-54 and 882-32×882-7 performed excellent in repeated trials, regional tests and production tests, and they were nominated as Zhongza 8 and Zhongza 9 respectively. Zhongza 8 and Zhongza 9, possessed several characteristics: (1) strong multiple resistance: high resistance to TOMV, mid-resistance to CMV, leaf mould and fusarium wilt; (2) tolerance to low temperature and weak light; (3)high fruit quality, high marketable percentage and resistance to cracking; (4) high yield. Zhongza 8 and Zhongza 9 are new varieties for protected cultivation. They contain cf5 gene and are highly resistant to ToMV and mid-resistant to CMV and Fusarium wilt.
