玉米是我省主要粮食作物。近年来,有关部门除了在管理方式和栽培技术等方面采取相应的措施外,一直强调高产自交系的应用,其目的是为了提高制种产量,降低生产成本,适应玉米生产发展的需要。本文针对这个问题,仅就低粒重玉米自交系在生产上的作用加以论述。一、百粒重与种子粒数的关系及应用分析一般条件下,玉米单交种的母本系产子量高,制种产量才能高,同时也相应提高了单交种本身的生产价值。但在生产上,有时仅以制种产量的高低来衡量某些同等生产水平单交种的种子应用价值,是不全面
Corn is the main food crop in our province. In recent years, the departments concerned have been emphasizing the application of high-yielding inbred lines in addition to the corresponding measures in terms of management methods and cultivation techniques. Their purpose is to increase seed production, reduce production costs and meet the needs of corn production. In this paper, this issue, only low-weight corn inbred lines in the production of the role to be discussed. First, the relationship between 100-grain weight and the number of seeds and application analysis Under normal conditions, the maternal maize single crossbred lines high yield, seed production to high, but also a corresponding increase in the production value of a single cross species itself. However, in production, sometimes only the level of seed production to measure the same level of production of single cross-species seed application value is not comprehensive
