根据我国玉米优势群划分结果,结合育种实践,将我国的玉米种质分为外引优势群、中国优势群和热带优势群3个;杂优模式为外引优势群×中国优势群、外引优势群×热带优势群和中国优势群×热带优势群。并对杂种优势类群划分及利用进行了探讨。
According to the result of heterosis group of maize, as well as the practice of breeding, the maize germplasm of China were divided into three heterosis groups including foreign heterosis group, China heterosis group and tropical heterosis group, respectively. The heterosis models are foreign heterosis group x China heterosis group, China heterosis gro,Jp x tropical heterosis group and foreign heterosis group x tropical heterosis group.
