Abstract
The ability of immature embryos of wheat (Triticum aestivum L.) to respond in cell culture was examined in crosses between the 'Wichita' monosomic series and a highly regenerable line, 'ND7532'. Segregation in disomic controls and 13 monosomic families showed a good fit to a monogenic ratio indicating a qualitative mode of inheritance. Segregation in the cross involving monosomic 2D showed a high frequency of regeneration (93.6%) and high callus growth rate (1.87 g/90 days) indicating that 2D is a critical chromosome. Modifying genes may be located on other chromosomes. Substitution of chromosomes from a low regenerable cultivar 'Vona' further indicated that the group 2 chromosomes, in particular chromosome 2D, possess genetic factors promoting callus growth and regeneration.
