Fig. 7.2 Protocol for pyramiding resistance value of polymorphic synthetic hexaploid wheats for
adding to breeding efficiency
could be combined via marker technology. Hence in the offing exists a genetic re-
source area that could combine desired SHs for enhancing recombination breeding
efficiency and for which the entire over a 1,000 D genome SH's of the D genome
and a couple hundred of the A genome await exploitation.
Additional Diversification from the A and B (S) Genomes
With production and maintenance protocols similar to those of the D genome diploid
accession SH derivatives, uniqueness of the A and B (S) genome synthetics resides
essentially in widening the variability resource that allows for novel allelic richness
to become user friendly and provide the wheat crop additional genes that would
be additive for resistance durability. The generated resource can not only enrich
