Other claims from this paper (10)
- Observation NR1121 wheat-rye derivative was immune to Puccinia striiformis isolate CY32.
- Observation Austrian rye was immune to Puccinia striiformis isolate CY32.
- Observation Shaanmai 611 and six Yr9 cultivars were susceptible to Puccinia striiformis isolate CY32.
- Mechanism The stripe rust resistance gene of NR1121 was derived from Austrian rye.
- Observation NR1121 had a stable chromosome number of 2n=42=21Ⅱ.
- Observation GISH showed that two chromosomes of NR1121 were transferred from S. cereale.
- Observation NR1121 possessed chromatin of Austrian rye 1R, detected by SCAR and SSR markers.
- Observation Gli-B1 in the omega region of NR1121 had the specific band of Austrian rye.
- Observation NR1121 is a wheat-S.cereale 1R disomic substitution line.
- Recommendation NR1121 could be used as a stripe rust resistance resource for wheat breeding.
