用四倍体野生种作母本与谷子杂交,F_1为三倍体,染色体不育,结实困难,欲测定上述母本对谷子现有核不育系有无胞质可育因子,亦须育出育性杂合的四倍体谷子作父本;若以现有谷子四倍体种为母本进行反交选育恢复系,则仍有去雄之累.为此,我们进行了谷子不育系同源四倍秋水仙碱引变试验,试图在四倍体水平上引用野生狗尾草的细胞质,达到选育谷子三系之目的. With tetraploid wild species as the mother and millet hybrids, F_1 ​​is triploid, chromosomal infertility, fruiting difficulties, to determine the maternal millet existing male sterile lines with cytoplasmic fertile factor, also need to educate Fertile heterozygous tetraploid millet as father; if the existing millet tetraploid as the female parent breeding selection and restore system, there are still tired of the male .To this end, we conducted a millet Four lines of homologous colchicine mutation test, trying to tetraploid level reference wild cypresses, to achieve the purpose of breeding millet three lines.
