近几年,武威地区遵循“大引进、大筛选,以引为主,培育为辅”的原则,按照优质、高产、多抗的要求,经过农业科技人员的不懈努力,玉米育种、引种工作取得了阶段性成果。一是玉米育种有了突破性进展。武威地区农科所选用的301、306、311、401、凉单2号(暂定名)等五个定型玉米杂交新组合,株型紧凑、秆粗、行数多、籽粒大,并且具有各自的抗性,平均亩(1亩=666.7m~2)产均比“凉单一号”高,基本可以作为“凉单一号”的接班品种。尤其是301新组合,已完成育种进程,
In recent years, Wuwei follows the principle of “big introduction, big screening, guidance and cultivation as supplement”. According to the requirements of high-quality, high-yield and multi-resistance, through the unremitting efforts of agricultural scientists and technicians, The stage results. First, there has been a breakthrough in corn breeding. Wuwei area of agricultural selected 301,306,311,401, cool single No. 2 (tentative name) and other five new combinations of stereotyped maize, compact plant type, coarse stalk, rows and more, large grains, and have their own Of the average mu (1 mu = 666.7m ~ 2) production than the “cool single” high, the basic can be used as “cool single” successor varieties. In particular, the new combination of 301, has completed the breeding process,
