Abstract This study give an account of the breeding efforts of high-protein maize varieties, particularly Quality Protein Maize (QPM), and their potential to address malnutrition and improve the nutritional value of maize. Compared to conventional maize, QPM varieties contain higher levels of essential amino acids such as lysine and tryptophan, which are crucial for human and animal nutrition. Research has shown that the adoption of QPM significantly improves children's growth, indicating its potential to combat malnutrition in developing regions. However, QPM breeding still faces challenges, such as reduced yield and insufficient agronomic traits. Future research directions include integrating molecular breeding with conventional methods, exploring genetic loci associated with protein synthesis and stress tolerance, and developing QPM varieties that are both nutritionally superior and agronomically viable.
