建立玉米品种特征数据库,对其进行数据化管理,是对玉米品种进行计算机管理的一项重要内容和发展方向。以新疆8个主要玉米单交种及其亲本自交系共24个材料为对象,采用VisualFoxPro6.0软件,建立融品种外形特征文字描述与图片显示及其酯酶同工酶、种子储藏蛋白电泳和RAPD指纹图谱及其数据为一体的品种特征数据库。该数据库具有更新方便,查询快捷等特点,可供种子检验部门和品种管理部门应用,以提高品种管理与品种鉴定的准确性和客观性。 The establishment of maize variety characteristics database, and its data management, is an important content of computer management of maize varieties and development direction. In this paper, 24 main materials from 8 major maize crosses in Xinjiang and their parents were used as research objects. By using Visual FoxPro 6.0 software, the characterization and picture display of glyphosate varieties were established and their esterase isoenzymes, And RAPD fingerprints and their data as one of the species characteristics database. The database has the features of convenient updating, quick inquiry and so on, which can be used by the seed testing department and the variety management department to improve the accuracy and objectivity of variety management and variety identification.
