For years, scientists have been trying to make crops permanently resistant [1] – unfortunately, to no avail. In the mid-1800s Gregor Mendel outlined the principles of heredity using pea plants and thus provided the necessary framework for scientific plant breeding. Plant breeding is an important tool in promoting global food security, and many staple crops have been bred to better withstand extreme weather conditions associated with global warming, such as drought or heat waves.

Breeding high-lysine maize varieties for those areas of the world where maize is the major source of this nutritionally essential amino acid has become a major goal in plant breeding. In this article we will discuss about the methods of plant breeding for disease and pest resistance. Its primary distinguishing feature is the presence of blocks (replications) of equal size, each of which contains all the treatments. In the conventional plant breeding programme, the development of a new variety or hybrid takes about five to twelve years, starting from inbred production and then hybridization and selection of F 1 hybrids. One of the aims of virtually every breeding project is to increase yield. This “biofortification” of food crops, a term which also includes genetic modification, has been shown to improve nutrition and is especially useful in developing areas where nutritional deficiencies are common and medical infrastructure may be lacking.
