Abstract
【Objective】The aim of this research was to identify the genetic chromatin transferred to NR1121 from S.cereal.【Method】The resistance to stripe rust pathogens of NR1121 was identificated.Chromosome analysis,genomic in situ hybridization(GISH),A-PAGE,SSR and SCAR were used to detect S.cereal chromatin in NR1121.【Result】NR1121 and Austrian rye were immune to isolate CY32 of Puccinia striiformis f.sp.tritici.Shaanmai 611 and six cultivars(Lovrin 10,Lovrin 13,Qingmai No.9,Fengkang No.8,Shaan229 and Yanshi No.9) with Yr9 were susceptible to CY32.The results indicated stripe rust resistanance gene in NR1121 was derived from Austrian rye.NR1121 was stable in cytology with chromosome numbers 2n=42=21Ⅱ.GISH analysis with Austrian rye genomic DNA as a probe showed that the two chromosomes of NR1121 were transferred from S.cereal.SCAR and SSR marker(Xgwm131-1B) detection indicated that NR1121 possessed chromatin of Austrian rye 1R.A-PAGE indicated that Gli-B1 in ω region of NR1121 had the specific band of Austrian rye.The result showed NR1121 had chromatin of Austrian rye 1RS.【Conclusion】NR1121 was a wheat-S.cereale 1R disomic subsititution line and immune to CY32.The resistant gene in NR1121 was derived from Austrian rye and probably a new gene different from Yr9.NR1121 could be used as resistant resource of stripe rust for wheat breeding.
