Abstract

Abstract: There are many reasons why the purity of conr seeds cannot reach the national standards,such as inbred lines heterogeneity;excess utlization generation of inbred lines;biology confounding;loosing field mangement;rogued by halves in seed airing;artifical concoction etc.Based on these reasons,some measures were taken to improve purity of seeds:careful expansion attiude,indred lines breeding,stable specializd and mechandizd seed production basis,strict conforming to“ Corn seed growing operating specifications”,strict to close seed quality,integritying management system,purifying seed market.

Key words: Corn growing, Purity reaches standards, Improve
