我省是野生稻资源地之一,分布广,资源丰富,并且野生稻长期处于野生状态,对各种自然灾害,不良环境具有高度的抵抗性或适应性,产量虽然很低,但还是育种中的重要亲本资源。此外,有些野生稻具有细胞质不育因子,是培育“三系”杂种优势利用的原始材料。因此,为了寻找较好的普通野生稻抗源供作杂交亲本,我们从1981年开始,与我院水稻所野生稻研究组协作,六年来共鉴定普通野生稻1626份,山蓝稻198份对稻瘟病的抗性,现将鉴定结果整理如下。
The province is one of the wild rice resources, widely distributed and rich in resources, and wild rice has long been in a wild state, and is highly resistant or adaptable to various natural disasters and adverse environments. Although the output is very low, it is still under breeding Important parent resources. In addition, some wild rice with cytoplasmic male sterility factor, is to cultivate the “three lines” heterosis utilization of the original material. Therefore, in order to find a better Oryza sativa resistance source for hybrid parents, we started in 1981, cooperated with the Oryza sativa research group of our institute. In the past six years, we identified 1626 common wild rice species and 198 wild Oryza species Rice blast resistance, now the identification results are organized as follows.
