| 摘 要： | 对麦田杂草二倍体节节麦（Triticum tauschii L．）的植株形态特征及根尖细胞染色体核型作了分析，并和六倍体普通小麦（Triticum aestivum L．）中国春核型作比较。结果表明，节节麦的核型公式为2n=2X=14=10M＋4SM（2SAT），在第4号染色体上有一对随体。节节麦染色体组和普通小麦中国春D组全套染色体类型相同，表明这两组染色体具有较强的同源性；但二者在染色体相对长度和臂比值上表现出一定的差异，表明该地区节节麦未参与普通小麦的起源。 |

| Abstract: | The morphologic character and chromosome karyotype of ruderal Triticum tauschii L.in cornfield were discussed,at the same time we compared the chromosome karyotype of Triticum tauschii L and Triticum aestivum L.The results showed: the karyotype formula of Triticum tauschii L.was 2 n=2 x=14=10 M (4 SM)(2 SAT),there were a pair of SAT in No.4 chromosome.that the genome classification of Triticum tauschii L.and Triticum aestivum L.was same,it shows that there was clear homology in the two genomes;but they were different in chromosome relative length and arm ratio,which indicated that the Triticum tauschii L.in Fengyang did not participate in genesis of Triticum aestivum L. |
