Hybrid Wheat Breeding and Commercial Seed Development

Following an account of the use made of the various genomes and cytoplasms of Triticum and Aegilops in hybrid wheat breeding, information is reviewed on the following hybridization methods: (1) cytoplasmic male sterility and pollen restoration, (2) chemical induction of male sterility and (3) single recessive genetic male sterility combined with chemical restoration. Sections are then devoted to (1) germplasm development and evaluation, (2) seed distribution and production, including parent and hybrid seed distribution, and (3) grain quality and yield in hybrids.
