【摘要】 为了选育耐贮藏的番茄,利用带有nor基因的LA1793番茄与普通栽培品种新锋4号,强力米寿,满丝,特罗皮克等进行正反交。研究了杂种一代果实的大小、产量、耐藏性和一些营养成分在贮藏期间的变化。结果表明:F₁的单果重、产量比普通栽培品种小、低。滴定酸、总糖量和维生素C在一般条件下长期贮藏后有所减少,但贮藏寿命可达两个月,比普通品种约长一倍。从对LA1793杂种一代的观察表明,另一亲本的耐藏性也直接影响F₁的贮藏效果。更多还原

【Abstract】 The studies on the fruits of F1 plants resulting from reciprocal crosses between"non-ripening" and normal tomatoes were carried out on Hainan Island and in Urumqi, Xinjiang, from 1983 to 1985. There was a reduction in the fruit size and yield of F1 hybrids as compared with normal tomatoes. The storage life of the fruits of F1 plants prolonged for about one month. The level of titratable acidity, total sugar, and vitamin C was reduced in the late stage of their storage. As there might be synthesis of vitamin C in the tomato fruits after harvest, vitamin C content did not decrease very much. Therfor these F1 can’t be used in production direclyt, because their small fruit and low output. But it provided possiblity to breed storage-resistance cultivars.更多还原
