US$ 199. Plant Breeding Impacts and Current Challenges Ancient Agriculture Agriculture began about 12 000 years ago, as the early farmers sowed and harvested plants that had previously been gathered in the wild. The relative advantages of mutation and recombination in plant breeding have been considered in relation to the genetic nature of the trait to be improved and the breeding system of the species.

Throughout the history of civilization, plant breeding has helped farmers solve complex challenges while also appeasing the appetites of consumers. Mutation breeding is the purposeful application of mutations in plant breeding. 1.10.3 Plant Breeding. Plant breeding is one of agriculture’s most effective tools for adapting to new circumstances. Plant breeding is the science driven creative process of developing new plant varieties that goes by various names including cultivar development, crop improvement, and seed improvement.

The end result of plant breeding is either an open-pollinated (OP for corn) or inbred (for rice) varieties or an F1 (first filial generation) hybrid variety. In addition, under changing environmental conditions plant breeding is even more desirable for the development of crop varieties resistant to multiple environmental stresses ( Ceccarelli et al., 2010 ). ...
