药用野生稻杂交后代对稻纵卷叶螟的抗性

Resistance of Filial Generation of Medical Wild Rice to Rice Leaf Roller

对药用野生稻杂交后代进行接虫试验和自然鉴定,研究药用野生稻与栽培稻杂交后代抗虫稳定性。结果表明:药用野生稻亲本Pc和种间杂交后代品系Ac鄄1、Ac鄄3对稻纵卷叶螟表现较高抗虫性,可为选育抗虫品种提供参考。

The interspecifie hybrid of medical wild rice(O.officinalis) and cultivatar variety(O.sativa) was inoculated in field for investigating its resistance to rice leaf roller.The results showed that medical wild rice (Pc) and the hybrid Ac-1 and Ac-3 had the strong-resistance to rice leaf roller,which could be used in rice insect-resistant breeding.
