国内外的经验证明,在杂交优势利用领域内,不育系来源的单一化,不仅直接限制了它的进一步利用,还会给生产造成或大或小的损失。而选育多种类型的不育系,用于配制多种类型的杂交组合则可适应不同自然区域的生产是非常必需的。滇瑞409杂交水稻的细胞质源有别于目前推广的野败型不育系,它的选育就是这样一种尝试。滇瑞409杂交水稻,是用滇瑞409不育系配制的杂交水稻的总称。我们对它的研究还很不够,现初步报导于后。 Domestic and foreign experience shows that in the field of heterosis utilization, the single source of sterile lines not only directly limits its further utilization, but also will cause greater or lesser production loss. However, it is very necessary to breed multiple types of CMSs and to prepare multiple types of hybrid combinations to adapt to different natural regions. Dianrui 409 hybrid rice cytoplasmic source is different from the current wild-type sterile lines, its breeding is such an attempt. Dianrui 409 hybrid rice is the generic name for hybrid rice formulated with Dianrui 409 sterile line. Our research on it is still not enough, is now initially reported later.
