The Haploid Technique In Barley Breeding
Kasha, K.J. and Reinbergs, E.
Haploid plants, containing only half the normal number
of chromosomes, have long been recognized as a potential
tool in shortening plant breeding programs. Research at
Guelph has shown that haploid plants can be produced in
cultivated barley following the interspecific cross with the
wild species Hordeum bulbosum. Subsequent chromosome
doubling leads to completely homozygous uniform lines.
The procedures for haploid production and how they might
be used in the barley breeding program are outlined.
