Plant regeneration from callus cultures of Durum and emmer wheat.

Callus cultures were initiated from isolated mature embryos of Triticum turgidum L. Thell ssps durum and dicoccum on a basal medium supplemented with 2,4-D, 2,4,5-Cl3POP or 2,4-D+CM. Shoot bud regeneration was observed on 2,4,5-Cl3POP medium. In both the cultivars of durum, further development of shoot buds occurred on transfer of tissues to basal medium whereas in dicoccum basal medium supplemented with coconut milk or coconut milk with NAA (0.2 mg/l) was necessary. The regenerated shoot buds were induced to root on basal medium supplemented with NAA. The in vitro obtained plants were transferred to soil and successfully grown to maturity. Chlorophyll variants were observed among the regenerated plants of dicoccum.
