应用一、鉴定非整倍体和其它畸变类型小麦端体首先用于单体的鉴定。要确定两个单体植株是否属同一染色体的单体,需要让二者杂交,而后出现一个缺体,或者出现一个双单体,这种测验需要多至50—100个F_1植株。但是当一个染色体是端体(或等臂体),并以它作父本与另一个单体杂交时,如果产生出单端体后代,就证实这两个单体品系所涉及的是同一染色体,而这种单端体出现的频率大约为 Application I. Identification of aneuploidy and other types of distortion Wheat ends are first used for identification of monomers. To determine if two monomeric plants are members of the same chromosome, hybridize the two and then present a nullbody, or a double monomer, which requires up to 50-100 F_1 plants. However, when a chromosome is a terminal body (or isobaric body), and when it is crossed with another cell as a male parent, if the single-terminal offspring are produced, it is confirmed that the two monomeric lines are involved in the same chromosome , And this single-ended body appears about the frequency
