Breeding Cross-Pollinated and Clonally Propagated Crops,with cross-pollinated species will differ from those used in self-pollinated crops. Also, the reproductive genetic structure in the major cross-pollinated crops will differ in detail from each other. This necessitates modifications in the procedure to fit the particular crop species, although the pr

Techniques in Breeding Field Crops,e plant breeder is no exception. In the practice of plant breeding, the breeder searches out or creates genetically mixed populations of plants, selects strains with desirable characteristics from the mixed populations, and tests the selected strains in pure lines or in combinations to determine if

Breeding Barley and Oats,worldwide in the production of grain, after wheat, corn, and rice. The major production areas are northern and western Europe and the USSR, where seasons are too short or too dry to grow feed grains such as corn or sorghum. In the United States and Canada, barley production is concentrated in the No

Breeding Soybeans,t half-century, it has become a major grain crop in the United States (Fig. 17.1) being third in production after corn and wheat, and second in value after corn. The rapid growth in production and importance of soybeans as a crop is unequalled in U.S. agriculture. Production of soybeans is centered

Breeding Sorghum and Millet, the semiarid tropics and subtropics. Sorghum is a major crop in Africa, India, portions of China, the southern and central Great Plains of the United States, Australia, Argentina, and areas of Mexico and Central and South America. Sorghum is a crop with extreme genetic diversity, but an overriding
