甜菜种质芽期耐盐性及鉴定方法的研究

A study on the salt tolerance and certified method of sugarbeet germplasm in germinating stage

通过对6份甜菜种质在不同浓度的NaCl盐渍下的耐盐性研究表明 :甜菜芽期耐盐性是受基因控制的 ,其广义遗传力h2B =51.12%;大批鉴定时NaCl浓度选在1.0%较适宜 ;评价指标以盐害系数为最好 ;6份甜菜种质的芽期耐盐性以7503/78为最好。

A study of salt tolerance carried out with 6 sugarbeet germplasm which soaked with different concentration of NaCl,the salt tolerance of gerinating stage controlled with gene,the broad-sense heritability h2B=51.12%. The optimum concentration of NaCl is 1.0%,certified index is the best with coefficient of salt injury,the best germplasm is 7503/78 for salt tolerance in germinating stage from 6 sugarbeet germplasm.
