| 摘 要： | 采用SDS方法纯化高粱总DNA，通过花粉管通道将高粱DNA转化P138、丹改340、7922、06NY-2、组3等5个品种的玉米自交系，后代的玉米种子经随机筛选后在实验室盆栽得到幼苗。使用不同序列的59条RAPD引物，对高梁基因组DNA和导入前后的玉米基因组总DNA进行PCR扩增。结果表明，其中9条引物在后代玉米和玉米原种之间具有RAPD差异，并证明了高梁DNA导入了4个玉米自交系，为今后的玉米自交系花粉管导入法育种的分子检验奠定了基础。

| Abstract: | The total DNA extracted and purified from the sorghum by new SDS method was introduced into 5 Maize varieties including P138, DG340, 7922,06NY-2, Z3 via a new improved pollen tube pathway. The seeds of different Maizes transformed were chosen by random sampling and their offspring were acquired in potted plant in lab then these offspring DNA was extracted in the same way. The different Maize genome DNA samples as well as the Sorghum genome DNA samples were respectively amplified by using 59 primers of RAPD. The results show that there are different genetic polymorphisms of RAPD in the used 9 primers between different Maize varieties and 4 different transformed Maize varieties. The results also indicate that the Sorghum genome DNA have been introduced into different Maizes. So this paper will lay the rudimentary foundation for success of genetic transformation in Maize breeding and the molecular verification among offspring performed by RAPD in the future |
