Abstract:

In order to facilitate the genetic transformation and germplasm innovation, compare the regeneration system difference between two pakchoi cultivars ‘Siyueman’ and inbred line 05-51 using different tissues. The result indicated that the explants of cotyledons with petioles were more efficient to induce adventitious buds. 3 mg/L 6-BA plus 0.5 mg/L NAA in MS basal medium was the most suitable hormone combination for adventitious buds induction. The regeneration rate was quite different among genotypes. Compared with 05-51, Siyueman was more inductive.
