摘要: 利用细胞学方法对2个普通小麦-Elymus rectisetus(Nees in Lehm)A.Lve et Connor衍生系1059A1和1063A1进行了鉴定,并对它们的细胞学稳定性、白粉病抗性、高分子量麦谷蛋白亚基组成和植物学性状进行了研究。2个衍生系在形态学和细胞学上已经基本稳定,根尖体细胞含有44条染色体,花粉母细胞减数分裂中期I(PMC MI)染色体构型为2n=22Ⅱ,与普通小麦亲本Fukuhokomugi杂交F1PMC MI染色体构型为2n=20Ⅱ+3Ⅰ。结果表明,它们均为普通小麦-E.rectisetus异代换-附加系。白粉病抗性鉴定结果表明,2种异代换-附加系高感白粉病。2种异代换-附加系及亲本的SDS-PAGE分析表明,它们的高分子量麦谷蛋白亚基组成与Fukuhokomugi相同。

Abstract: Cytogenatic technique was used to identify two Triticum aestivum一Elymus rectisetus (Nees in Lehm)A. Love et Connor derivatives.Additionally, their cytogenetic stability,resistance to powdery mildew, high-molecular-weight sub-unit of glutenin (HMW-GS),and morphologic were studied. Chromosome numbers in the root tips and chromosome configu-ration at PMC MI of two derlvatives were 2n= 44 and 2n=22 II. Chromosome configurations at PMC MI of hybrid Fl be-tween two derivatives and Fukuhokomugi were 2n=20 Ⅱ+3 I.The results showed that two derivatives were Triticum aes-tivum一Elymus rectisetus alien substitution addition lines. It was found that E.rectisetus accession 1050was highly resis-tant to powdery mildew,and two alien substitution addition lines and Fukuhokomugi were high1y susceptible.Two lines was the same HLVIW-GS as Fukuhokomugi.

Key words: Elymus rectisetus, Cytogenctics, Alien substitution addition lines, HMW-GS
