Effects of genotype and AgNO3 on shoot regeneration in winter cultivars of rapeseed (Brassica napus).
Ability of shoot regeneration from cotyledon explants of rapeseed (Brassica napus) winter genotypes and the effect of silver nitrate and naphthalene acetic acid in shoot regeneration were investigated. The optimum medium for regeneration was the medium supplemented with 3 mg L(-1) 6-Benzylaminopurine and 0.15 mg L(-1) 1-naphthaleneacetic acid. The addition of 5 mg L(-1) silver nitrate significantly improved shoot regeneration. Shoot regeneration response was strongly different between genotypes with a range of variation from 79% in spring genotype PF and 7% in Okpi. The highest root production was recorded on medium containing indol-3-butyric acid. The rooted plants successfully transferred to soil and adapted to greenhouse conditions. No abnormally was observed and the regenerated plants were morphologically similar to the field grown parental plants.
