体细胞杂交是作物育种的新途径,已经取得了很大进展.不对称融合技术主要通过射线辐照供体细胞,使只有胞质基因或部分核基因进入受体,从而增加获得可育杂种植株的可能性,为有性不亲和的种属间的杂交创造了有利的条件.簇毛麦(Haynaldia villosa,2n=14,VV)属于小麦亚族簇毛麦属.它具有小麦缺乏的许多优点,如高度抗病性、高蛋白质含量及分蘖能力强等.但小麦
Somatic hybridization is a new way of crop breeding, and great progress has been made.Asymmetric fusion technology mainly irradiates donor cells by radiation, so that only cytoplasmic genes or some nuclear genes enter the receptor, thereby increasing the availability of hybrid plants , Which provided the favorable conditions for crossbreeding between sexually incompatible species.Halnaldia villosa (2n = 14, VV) belonged to the wheat sub-family Synechococcus, which had many wheat deficits Advantages, such as high disease resistance, high protein content and tillering ability, etc. But wheat
