番茄杂种优势的利用,通过几年的试验研究,目前在国内许多地方已经广泛地应用于生产。如杭州市郊杂种一代番茄的种植面积,已经占到番茄总面积的90%以上,对番茄产量的提高起了很大作用。但是,目前的杂交制种,仍然沿用去雄授粉的方法,不仅花的劳力多,成本高,而且杂种纯度也较低。解决这一问题的方法之一,是利用相应的雄性不育系作为母本,来生产杂交种。据国内外已有研究的材料报导,番茄的雄性不育,属于细胞核遗传的核质不育类型。其中有功能性雄性不育型、长花柱型、有雄蕊花粉不育型,以及无雄蕊型等。近年来,大同市南郊蔬菜研究所曾选得雄蕊退化,但花药中尚存有少量功能正常花粉的雄
The use of tomato heterosis, through several years of experimental research, is now widely used in many places in the country. For example, in the suburbs of Hangzhou, the planting area of the hybrid generation of tomatoes has accounted for more than 90% of the total area of tomato, which has played a significant role in the improvement of tomato production. However, the current crossbreeding still uses the method of pollination, which not only takes more labor, but also has higher cost and lower hybrid purity. One of the ways to solve this problem is to use the male sterile lines as the female parent to produce hybrids. According to the reports of materials from both home and abroad, the male sterility of tomato belongs to the type of nuclear cytoplasmic cytoplasmic male sterility. Among them are functional male sterility type, long style, stamen pollen sterility, and non-stamen type. In recent years, the southern suburbs of Datong Vegetable Institute stamens have been selected degradation, but there are still a small number of anthers functionally normal male pollen
