| Abstract: |
| Four plant (ear) lines that were immune or highly resistant to stripe rust were selected by the crossing of spring wheat and Thinopyrum intermedium disomic addition line Z4. Plant height and other agronomic characters were classified and analyzed. The results showed that the range of genetic variation coefficient of various characters was 8.04%149.59%. The variation coefficient of ears per plant was the largest and that of grain weight per ear and 1000-grains weight was the next. The effects of heredity and variation of main yield characters are valuable to the breeding of wheat variaties with high yield. The synthetical qualitaty trait of 1343-1 was the best. In general, the content of seed protein was all over their two parents, while the content of wet gluten and zeleny was all between their two parents or showed negatively genetic effects. |
