利用南京农业大学细胞遗传研究所育成的一套涉及不同簇毛麦染色体的异附加系和代换系以及 5个 6 VS/ 6 AL易位系 ,经 1997、1998、1999连续 3年在陕西、北京、四川进行小麦条锈病抗性接种鉴定 ,结果表明普通小麦 -簇毛麦 6 V异附加系 ,6 V(6 A)异代换系和 6 VS/ 6 AL易位系高抗条锈病菌条中 2 9、条中 31、水源 11- 2、水源 11- 5、水源 11- 13和杂 4 6 等强毒小种。考虑到含整组 V染色体的硬粒小麦 -簇毛麦双倍体不抗水源 11- 13小种 ,上述普通小麦 -簇毛麦 6 V异附加系、异代换系和 6 VS/6 AL易位系的条锈病抗性可能还与其所涉及的小麦亲本基因的作用有关
Using a set of heterologous and substitutional lines involving different chromosomes and five 6 VS / 6 AL translocation lines, the Institute of Cytogenetics of Nanjing Agricultural University bred three consecutive years in 1997, 1998 and 1999 in Shaanxi, Beijing, and Sichuan Province. The results showed that the 6 V (6 A) alien addition lines, the 6 V (6 A) alien substitution lines and the 6 VS / 6 AL translocation lines were resistant to Stripe Rust Resistance Article 29, Article 31, water 11- 2, water 11-5, water 11- 13 and miscellaneous 4 6 and other virulent races. Considering that the durum wheat-Hamaeroidum haploid, which contains the entire group of V chromosomes, is resistant to 11-13 race species, the above-mentioned common wheat-Hamster 6-V alloplasmic lines, Stripe rust resistance of the translocation line may also be related to the role of the wheat parental genes involved in it
