摘要
在玉米群体改良的同时，结合进行玉米自交系和杂交种的早期选育，以一般配合力和特殊配合力等遗传参数作为自交系和杂交种选育的依据，将玉米群体改良和常规育种紧密结合，加快育种进程和提高群体改良的利用价值。
During the maize population improvement, the inbred lines and hybrids of maize are selected and bred at the same time. According to the genetic parameters such as general combining ability, special combining ability, and so on, we combine the maize population improvement with routine selection and breeding of maize, which can accelerate the process of breeding and utilizing improved populations.
