采用非洲长药野生稻与柳州野生稻杂交转育，育成了早显Ａ新不育系。利用这一种质资源导入其他育种材料，将实现早熟基因在杂种优势中的利用，从而可克服杂交水稻早熟性与丰产性的矛盾。
The cross of African longan wild rice and wild rice of Liuzhou was crossed and bred, and a new male sterile line of early A was bred. The introduction of other breeding materials with this kind of germplasm will realize the utilization of the early maturity gene in the heterosis, so as to overcome the contradiction between the early maturity and high yield of hybrid rice.
