关于雄性不育问题 Sears(1947)分为细胞质不育、质核互作不育、核不三种类型;Edwar-dson(1970)在 T 型玉米筛选出恢复系之后,认为不存在细胞质不育,提出二型说;木原君(1968)通过不同细胞置换反应,认为可育和不育是核——质协调问题,所谓核不育实际上是暂时找不到保持系而已,称为一型说。1972年我国山西太谷县高忠丽发现一株不育小麦,经中国农科院邓景阳先生鉴定是无花粉型,细胞质正常的显性核不育,命名为太谷(Ta_1)显性核不育。该研究首肯了核不育在理论上的重大意义以及在实际应用上的巨大潜在价值,1980年公开后立即为国内外专家所瞩目,曾被一度冷落了的核不育育种再度掀起热潮,为我国的核不育应用开创了先河。在此以后,我国又在几种作物中发现了自然突变雄性不育单
Sears (1947) on male sterility is divided into three types: cytoplasmic male sterility (CMS), infertility of nucleus and nucleus. Edwar-dson (1970) did not find cytoplasm infertility , Proposed two types of said; Muhara Jun (1968) through different cell replacement reaction, that fertility and infertility is the nuclear-quality coordination problem, the so-called nuclear infertility is actually temporarily not found to maintain it, known as a type Say. In 1972, our country Shanxi Taigu County Gao Zhongli found a sterile wheat, identified by the Chinese Academy of Agricultural Sciences Mr. Deng Jingyang pollen-type, cytoplasm of the normal dominant male sterile, named Taigu (Ta_1) dominant male sterile. This study approved the theoretical significance of nuclear infertility and its great potential value in practical application. It was immediately noticed by domestic and foreign experts immediately after its publication in 1980 that once again set off an upsurge of neglected sterile breeding for China’s nuclear infertility application pioneered. Since then, our country has found a natural mutation in several crops of male sterile single
