蕃茄野生种(Lycopersicon),以及栽培种(Desculentum)的野生型对培育改良的栽培品系贡献相当大,并将起越来越重要的作用。这些品种至少对13种不同的病害具有抗性,且已被导入重要的、广泛种植的栽培品种,部分地或全部地解决了病害防治问题。此外,这些基因组合,在同一栽培品种中,对多达8种不同的病害具有抗性。野生蕃茄作为种质资源也能达到别的目的。例如从野生的、结小青果的L. Chmielewskii(秘鲁东科迪勒拉山脉的土生种)引出的基因已提高了可溶性碳水化合物的含量。和典型的加利福尼亚加工蕃茄4~5%的可溶性物质含量相比,这一野生品种果实中可溶性物质的含量可达10~11%。我们研究
Lycopersicons, and the wild type of cultivars, contribute significantly to the cultivation of improved cultivars and will play an increasingly important role. These cultivars are resistant to at least 13 different diseases and have been introduced into important, widely cultivated cultivars to address disease control problems, either partially or fully. In addition, these gene combinations are resistant to as many as 8 different diseases in the same cultivar. Wild tomatoes as germplasm resources can also achieve other purposes. For example, genes from L. Chmielewskii, a native, small-fruit-bearing L. chinensis (native species of the eastern Cordillera in Peru) have been raised in soluble carbohydrates. Compared to 4% to 5% of soluble matter in typical California processed tomatoes, the soluble content of this wild variety is 10-11%. We study
