水稻选育种途径很多。但要选育出有重大突破的新品种,重要的一点就是要扩大种质资源,选配恰当的亲本。笔者在多年育种实践中体会到,利用野生稻与栽培稻进行杂交育种,是一条卓有成效的途径。1980年以来,笔者利用增城县的一年生野生稻与“桂朝2号”进行杂交育种,充分证明利用野生稻与栽培稻杂交育种,可以有效地选育出多种多样优质、高 There are many ways to breed rice. However, to breed new breeds with major breakthroughs, it is important to expand the germplasm resources and select appropriate parents. The author of many years of breeding practice experience, the use of wild rice and cultivated rice hybrid breeding is an effective way. Since 1980, the author made use of the annual wild rice in Zengcheng County and “Guichao No.2” for crossbreeding, which fully proved that the use of wild rice and cultivated rice cross breeding can effectively breed a variety of high quality, high
