摘要
对高原602双胚苗的细胞学进行了研究，有3种类型：2n－2n、2n－3n和2n－n，出现频率分别为0．16％、0．02％和0．02％。在2n－2n型里，又发现了形态上的差异，即2n（顶芒）－2n（长芒）。对单倍体育种和三倍体的起源进行了讨论。
Cytological studies in biembryonic seedling of Plateau 602 were carried out.There were three types of cytology: 2n－2n, 2n－3n and 2n－n. Respective1y, their frequencies were 0.16%,0.02% and 0.02%. We found morphological difference in 2n－2n types,2n (top awn)－2n (long awn). The haploid breeding and the origin of triplont are discussed.
