Effects of growth regulators on in vitro plant regeneration in durum wheat.(Genomics, Molecular Genetics & Biotechnology)

Crop Science, September, 2004 by Elias, E.M.; Jauhar, P.P.; Rao, M.B.; Satyavathi, V.V.

Work un improvement of durum wheat (Triticum turgidum L.) using tools of biotechnology is limited. Development of a reliable in vitro plant regeneration procedure for this important cereal is a prerequisite for its improvement by genetic transformation. Here, we report the effects of three growth regulators (GRs), 2,4-D (2,4-dichlurophenoxyacetic acid), picloram (4-amino-3,5,6-trichloropicolinic acid), and dicamba (3,6-dichloro-o-anisic acid), on callus induction and plant regeneration from scutellum cultures of four commercial durum cultivars: Ben, Mater, Munich, and Lebsock. Callus induction was obtained from isolated scutella cultured on modified Murashige and Skoog (MS) basal medium. After 4 wk of callus induction, all calli were plated on MS basal medium for regeneration. The...
