Callus Culture and Gamma-Ray Treatment used for Inducing New Breeding Material in Wheat (Tr.Aestivum L.)

ABSTRACT

Two winter wheat (Tr.aestivwn L.) lines 8–61 and 148–133–14 were used in this study. Callus culture and gamma-ray treatment were combined for inducing new initial breeding material. As a result of the present investigation three lines with increased spike length were developed from 8–61 regenerants. For 148–133–14 regenerants a new form with a higher spike length and number of spikelets per spike was obtained. The generation of new forms depends both of gamma-ray treatment and genotype specificity.
