| Abstract: | In the past decades,the plant genetic engineering technology in improving the yield and quality of Brassica napus L.had been greatly developed.Establishing an efficient and stable regeneration system of explant is one of the important segments of genetic engineering breeding.In this study,hypocotyls of Brassica napus L.were used as the explant,and the callus induction ratio was analyzed under different genotypes,seedling ages and combinations of various hormones.The results showed that Yangyou 6 hypocotyl explant had the largest contribution on the callus formation under the same tissue culture conditions,and the best conditions of callus formation was the 5 d age seedling,pre-culturing for 3 d,culturing in the medium containing 0.1 mg·L-1 2,4-D,1.0 mg·L-1 6-BA and 5.0 mg·L-1 AgNO3. |
