小麦种质资源材料‘中4’是我国重要的小麦抗条锈亲本材料。自1994年以来连续多年进行接种鉴定和自然诱发鉴定,发现‘中4’在苗期及成株期对接种及自然诱发的条锈菌均表现免疫,抗病性表现优异。2007-2011年选用1 893份甘肃省小麦条锈菌单孢菌系进行毒性分析,仅有9个菌系对其有毒性,占0.49%。苗期接种26个国内外具有不同毒性谱的条锈菌单孢菌系,基因推导分析含有未知抗病基因。在育种中具有较好的利用价值,值得进一步研究利用。
Wheat germplasm material ’4’ is an important wheat stripe rust parent material. Inoculation identification and natural induction identification have been carried out for many years since 1994 and it was found that ’Zhong 4’ showed immunization against both the inoculated and naturally induced stripe rust at the seedling and adult stage, and showed excellent disease resistance. A total of 1 893 copies of the stripe rust isolates of wheat from Gansu Province were selected for toxicity analysis in 2007-2011. Only 9 strains were toxic to them, accounting for 0.49%. 26 seedlings were inoculated with 26 virulent strains of P. aeruginosa at home and abroad, and the gene deduction analysis contained unknown disease resistance genes. In breeding has good value, it is worth further study and utilization.
