摘要： 用染色体 N—分带技术对四倍体小麦(AABB 和 AAGG)以及 B 和 G 染色体组的可能供体拟斯卑尔脱山羊草(Ae.speltoides)、高大山羊草(Ae.longissima)、沙融山羊草(Ae.sharonensis)、二角山羊草(Ae.bicornis)和西尔斯山羊草 Ae.se-arsii 的体细胞染色体进行核型分析。除染色体4 A 以外的所有 A 组染色体只有较浅的 N—带或无带。B

Abstract: The somatic chromosomes of tetraploid wheats(AABB and AAGG)and probable donors of B and G genomes Ae.speltoides,Ae.longissima,Ae.sharonensis,Ae.bicornis and Ae.searsii were identified by an N-ban-ding technique.All chromosomes of A genome but 4A were banded withweak bands or no band.There was genera
