What are the varieties of high-yield and early-maturing corn?

Corn farmers all know that corn is divided into early-maturing corn, medium-maturing corn and late-maturing corn. Generally speaking, early-maturing varieties mature 25 to 34 days after pollination, mid-maturing varieties mature 35 to 40 days after pollination, and late-maturing varieties maturing after 40 days. In order to obtain a lot of economic benefits, many corn farmers choose early-maturing varieties, so what are the high-yield and early-maturing corn varieties?
