甜菜种质的性状改良与创新

Characteristics Improvement and Creation of Sugar Beet Germplasms

通过“七五”至“十五”期间甜菜种质资源的主要农艺性状鉴定、品质分析和种质创新研究,鉴定、筛选出一大批丰产、高糖、抗病的种质资源材料,同时对其性状改良,创造出一些经济性状优良、适应性强、配合力高、遗传稳定的新型优异种质,有的已做为预选种应用于我国的育种实践中,并育成新品种在生产上大面积推广应用。

A lot of sugar beet germplasms with high yield and high sugar content as well as disease resistance have been identified and selected through the appraisal of main agronomic traits,quality analysis and germplasms creation from Seventh Five-Year Plan to Tenth Five-Year Plan,and some novel superior germplasms with good economic characters,superior adaptability,good combining ability and genetic stability have been created,which have been applied to breeding as pre-breeding,new varieties have been bred to commendably serve for sugar beet production.
