Genetics of regeneration of wheat (Triticum aestivum L) plants

Five genotypes of hexaploid wheat and their Fl hybrids were grown in tissue culture after three different periods bf callus maintenance, and were evaluated for plant regeneration capability. Evaluation of the number of regenerated plants per callus showed that this trait is mainly determined by additive gene effects, with high heterotic potential. Plant regeneration capability is relatively easy to select for, especially when; this regeneration is obtained af ter a short period of callus maintenance. Longer periods of callus maintenance led to a considerable reduction in plant regeneration capability in wheat.
