目前,六倍体和八倍体小黑麦育种工作取得了较大进展,在成熟度、种子饱满度、株高、抗病性、遗传不稳定性等方面均有所突破。但是,各种杂交后代性状的稳定性对选育工作带来很大困难。如当年选到农艺性状整齐并合格的材料,到第二年就出现育性不稳和性状分离,使育种工作者往往无法下决心。为了提高小黑麦育种的准确性和有效性,我们对杂种材料减数分裂的系统观察, At present, the breeding of hexaploid and octagonal triton has made great progress, with breakthroughs in maturity, seed fullness, plant height, disease resistance and genetic instability. However, the stability of the characters of various crossbreds poses great difficulties in breeding. For instance, when the materials of agronomic traits and qualified materials were selected, the instability of fertility and the separation of traits will appear in the second year, so that breeding workers often can not make up their minds. In order to improve the accuracy and effectiveness of triticale breeding, we systematically observed meiosis of hybrid materials,
