Abstract

In vitro plantlet regeneration was obtained from cultured cotyledon and young leaf explants of five Indian chile pepper cultivars (Capsicum annuum L. cvs. Gujarat-1, Gujarat-2, Guntur-4, Selection-49, and Jwala). Adventitious shoot buds (ASB) were regenerated directly from cotyledon and young leaf explants in all the five cultivars on media containing benzyladenine (BA) alone or in combination with 1-naphthaleneacetic acid (NAA). Regeneration frequency was highly influenced by cultivar explant type, media combination and their interactions, except the interaction between cultivar and explant, for number of ASB per explant. Percent contribution of individual source suggested that selection of explant type followed by medium combination and cultivars was essential for obtaining high-frequency ASB induction. Across different cultivars the young leaf explant was found to be the most responsive explant, while Murashige and Skoog (MS) medium containing BA alone (17.8, 26.6, and 35.5 μM) was found to be the best medium for the production of maximum number of ASB. Between the two explants, shoot elongation was observed with ASB obtained from young leaf explants on MS medium containing BA (2.2 and 4.4 μM) and gibberellic acid (GA3) (1.4, 2.9, 4.3, and 5.8 μM). The MS medium fortified with 4.4 μM BA 2.9 μM GA3 was optimum for shoot elongation. Elongated shoots were rooted on liquid MS medium supplemented with 2.9 μM indole-3-acetic acid (IAA) and successfully established ex vitro.
