![]() ![]() ![]() The breeding of QPM involves the manipulation of three distinct genetic systems. Maize breeders began transferring opaque-2 genes into local maize varieties, and they enthusiastically rushed the new crop into production. Quality protein maize (QPM) is a maize variety that possesses significantly higher levels of two essential amino acids, lysine and tryptophan as compared to Normal Maize (NM) varieties, to the presence of the opaque-2 gene in a homozygous recessive state. Due to this reason substituting the normal maize grown in developing country with QPM would substantially improve the protein status and greatly reduce the malnutrition problems of resource poor people depending on maize as staple food. But almost all maize varieties cultivated in the Ethiopia are normal maize varieties, which are deficiency of essential amino acids such as lysine and tryptophan and exposed to malnutrition people feed maize as stable food. Maize (Zea mays L.) is a major cereal crops in the World and stable food crops in developing countries. ![]()
