초록

An efficient procedure was developed for adventitious shoot bud induction and plantlet regeneration from various explants of the ten genotypes of Pepper (Capsicum annuum L.) using Thidiazuron (TDZ). Among various treatments at 1.0-3.0 mg/L TDZ Induced maximum number of adventitious shoots depending upon the explant type and genotype compared to other treatments. Among the explants tested, leaf induced maximum number of adventitious shoots than the cotyledons. TDZ-mediated organo-genesis was possible in 10 pepper cultivars, the extent of the response being genotype-dependent. Of the ten genotypes tested, C. annuum cvs CA960, $G_4$ and X-235 were produced maximum number of adventitious shoots and Sell was the least, and all other genotypes gave moderate response. Elongation of multiple shoots was observed on medium supplemented with SA (0.05 mg/L) in combination of IAA (0.05 mg/L). Differences in ability for in vitro shoot regeneration and elongation depend upon the variety and explant type. The elongated shoots were success. Fully rooted on MS medium containing at 1.0 mG/L IAA. Plantlets regenerated from different explants of ten genotypes were found to be diploid (2n=24) and were devoid of any chromosomal aberrations. Regenerated plants were successfully established in soil where 85-90% of them developed into morphologically normal and fertile plants.
