甜菜优异种质资源创新利用与评价
Evaluation of Superior Sugarbeet Germplasm Sources
【摘要】 通过对107份甜菜种质的主要农艺性状鉴定和品质分析,鉴定筛选出一批甜菜优异种质资源。再经两年多点的异地鉴定试验,对其参试种质的丰产性、高糖性和抗病性进行综合的评价及稳定性分析,从中选出9份产质量性状非常稳定的优异种质材料,其中优异种质79018具有丰产性、抗褐斑病及适应性好等特点,达到了国家甜菜优异种质一级标准,目前已被国内主要甜菜育种单位配制杂交组合,并参加区域试验。
【Abstract】 Some fine sugarbeet germplasms have been selected and identified through the appraisal of main agronomic traits and quality analysis from 107 germplasms. These germplasms on high yield and high sugar content as well as disease resistance were synthetically evaluated and analyzed on stability by different area identification for two years, 9 of them were fine and stable. The line 79018 was the most excellent one, and the line is now used to hybridize combinations and to join regional test.
