✦ Synopsis
The influence of genes affecting the `plant growth habit' in wheat (Rht8 and Ppdl) and rye (ctl and ct2) on tissue culture response was studied using immature embryos . Whereas the semi-dwarfing gene Rht8 seems to promote only a minor effect, the day-length sensitive allele ppdl determined a major increase in callus growth and regeneration ability . With regards to their tissue culture efficiency, the four alleles studied could be ranked as follows : ppdl > Rht8 > rht8 > Ppdl .
In contrast to wheat, the GA insensitive semi-dwarfing genes of rye (ctl and ct2) appear not to influence in vitro response .
