The word maize was originated from Spanish word 'Maiz' and it is domesticated variant of teosinte (Zea mexicana). Maize was domesticated first by natives of Mesoamerica. In Mexico, more diversity of maize has been reported (Khan et al., 2019). In 2018, maize had 1147.62 million tons production all over the world and in Asian region it had 361.56 million tons production. Asian region shares 31.51% of the total maize world production. Nepal produced 2.47 million tons maize Abstract | The yield attributes of maize, open pollinated varieties and hybrids were compared to the local varieties in Nepal, as the adoptability of these cultivars will cause variations in maize productivity. A total of 10 maize genotypes were evaluated in randomized complete block design with three replications during summer
