The results of early plant-breeding procedures were conspicuous. Of tropical origin, grain sorghum was largely confined to the southern Plains area and the Southwest, but earlier-maturing varieties were developed, and grain sorghum is now an important crop as far north as North Dakota. The post graduate teaching programme M.Sc.(Ag.) Improved varieties are developed through plant breeding. People caused changes in the plants that were used for agriculture and, in turn, those new plant types allowed changes in human populations to take place.

Uniformity of plant characters is very important in mechanized agriculture because field operations are much easier when the individuals of a variety are similar in time of germination, growth rate, size of fruit, and so on. Condition: Brand New. The NAPB is the outreach group that represents plant breeders in federal, state, commercial and non-government organizations. "What, we still need plant breeding? After that point the plant breeder can work with the genetically engineered line in the same manner they work with other parents in their breeding program. Quantity: 3 available. For example, a farmer who wants to select a plant with resistance to an insect pest will watch for the plants that survive an insect attack. Another common goal of plant breeding is to extend the area of production of a crop species. Sc.
