随着我国玉米育种水平的不断提高,耐密型品种在生产上大面积推广,推广机械化收获将是节约成本、增加效益的有效手段。目前推广的玉米品种与机械化收获之间存在不相适应的问题。以提高品种耐密性为核心,持续增加种植密度,同时重视品种机械化作业特性将是未来品种选育的主要方向。探讨了耐密宜机收玉米品种及自交系选育和鉴定的方法,以期抛砖引玉,不断提高我国玉米育种水平。
With the continuous improvement of maize breeding in China, the popularization of high density varieties in the production of large-scale promotion of mechanized harvest will be an effective way to save costs and increase profits. There is an incompatible issue between the current promotion of maize varieties and the mechanization of harvest. In order to improve the variety density as the core, continue to increase the planting density, while emphasis on varieties of mechanized operations will be the future direction of the main varieties of breeding. The methods of breeding and identification of maize varieties and inbred lines which are resistant to Mianyangzi were discussed in order to promote the maize breeding in China.
