一、前言小麦雄性不育研究始于50年代,1951年Kihara报导把小麦细胞核代换到尾状山羊草的细胞质中,引起胞质雄性不育,但是尾状山羊草细胞质的缺点在它在造成雄性不育性的同时,还会引起雌蕊畸型,导致结实率降低(Porter等1965)。1962年,Wilson和Ross把普通小麦的核代入提莫菲维小麦的细胞质

I. INTRODUCTION The research on wheat male sterility began in the 1950s. In 1951, Kihara reported that the nuclear of the wheat cell was switched to the cytoplasm of caudate goat grass, causing cytoplasmic male sterility. However, the shortcoming of caudate goat grass cytoplasm was that it caused Male sterility at the same time, can also cause pistil deformity, resulting in reduced seed setting (Porter et al 1965). In 1962, Wilson and Ross introduced common wheat nuclei into the cytoplasm of Timofeev
