引言栽培蕃茄(Lycopersicon esculentum Miller)是茄科植物(Solanaceae)中得天独厚的一个种。在一般情况下,像一年生植物那样生长,但能通过一些措施使它能像多年生植物那样进行无性繁殖。蕃茄种植范围广泛,种植技术简单,它的生长和繁殖不受昼长或其它特殊条件的限制。蕃茄的表现型,尤其像叶形、品质和色泽等特性在其遗传饰变的大量变种中易于辨认。虽然蕃茄正常地进行自花授粉,但通过人工授粉易于获得杂交种子。一个发育完全的植株能产生10,000—25,000粒种子。它的种子和花粉长期贮藏 Introduction Lycopersicon esculentum Miller is a bounty of Solanaceae. Under normal circumstances, it grows like an annual plant, but by some measures it can be cloned like perennials. Tomato is grown in a wide range and has simple planting techniques. Its growth and reproduction are not limited by day length or other special conditions. Tomato phenotypes, especially like leaf shape, quality and color, are easily identified in a large number of varieties of their genetic modification. Although tomatoes are normally self-pollinated, hybrid seeds are readily obtained by artificial pollination. A fully developed plant produces 10,000-25,000 seeds.
