Heptaploids were obtained by back crossing(common wheat×P. huashanica) F1 with common wheat. The disomic addition plants were produced by crossing the heptaploids with common wheat followed by selfing BC1F1 hybrids and selecting 2n=43 plants. If the heptaploid was used as male, the frequency of monosomic addition (24.2%) was higher than that if the heptaploid was used as female (12.28%). The frequency of disomic addition plants derived from selfing monosomic addition plants was 7.19% .The cytological stabilities among addition lines were different and increased with generations.
