| Abstract: | The spikelet numbers of common wheat lines with added or substituted chromosomes of Lophopyrum elongatum were screened. It is found that chromosome 4E e of Lophopyrum elongatum has a strong positive effect on the spikelet numbers of common wheat, and chromosomes 1E e and 5E e has a faint positive effect. |
