沙田柚(Citrus grandis var.shatinyu)系我区特产,肉脆味甜,驰名中外,深受欢迎。但种子太多,从而大大降低了其经济价值。目前国际市场上畅销的柑桔类果品均为无核或少核。因此,培育无核或极少核类型的沙田柚优良变异类型,以适应国内外市场发展的需要,乃是当前一项迫切的育种任务。本研究的目的是对我区沙田柚进行辐射诱变育种的探索。 Citrus grandis var.shatinyu is a specialty of our region, crisp and sweet, well-known at home and abroad, very popular. But too much seed, which greatly reduces its economic value. At present, the best-selling citrus fruits in the international market are all non-nuclear or less nuclear. Therefore, it is an urgent breeding task to cultivate the fine variation type of non-nuclear or rare nuclear type in order to meet the needs of market development at home and abroad. The purpose of this study is to explore the radiation mutagenesis breeding of Shatian pomelo in our district.
