在生物物种进化的过程中,发生了多种多样的基因突变,经过人工选择和自然选择,每个物种都产生了各具特色的类型和品种。显花植物的雄性不育现象是人们首先注意并加以研究利用的遗传变异之一（刘秉华,1991）;雌性不育虽也有发现,但迄今为止,对其产生的内在机制还知之甚少;受一套遗传基因控制的既雄性不育,又雌性不育的材料是一种罕见的自然现象,仅在少数植物上发现过（Palmer,1992）,小麦中尚未见有报道。雌雄性不育材料是一种奇特的遗传资源,通过深入研究,一定会发现许多有用的遗传信息。
In the course of the evolution of biological species, a variety of genetic mutations have taken place. After manual selection and natural selection, each species has its own unique types and varieties. The male sterile phenomenon of the flowering plants is one of the genetic variations that people first noticed and used for their research (Liu, 2011). Although female infertility has also been found, so far, little is known about its internal mechanism. A set of gene-controlled male-sterile and female-sterile materials is a rare natural phenomenon that has been found only in a few plants (Palmer, 1992) and has not been reported in wheat. Male and female sterile material is a peculiar genetic resource, through in-depth study, will certainly find many useful genetic information.
