Other claims from this paper (8)
- Observation Seedling resistance to stripe rust segregated 149 resistant to 52 susceptible among 201 F2 seedlings.
- Association The 3:1 segregation indicated one dominant gene conferring CYR31 resistance.
- Observation F5 lines segregated 1:1, supporting single-gene resistance.
- Observation 5-1-2-1-1-5 was identified as an alien addition line with 2n = 42 + II.
- Observation 5-1-2-1-1-6 was identified as an alien addition line with 2n = 42 + II.
- Observation GISH identified both lines as wheat-Th. intermedium disomic additions with 21 wheat chromosome pairs and one Th. intermedium pair.
- Observation Both addition lines resisted stripe rust.
- Recommendation The authors propose both lines as stripe rust resistance donors for wheat breeding.
