2013年国家甜菜品种区域试验品种稳定性测定

通过对2013年国家甜菜品种区域试验8个品种15个地点试验结果的统计分析,求得品种＆#215;地点互作效应值（VU）ij、变异系数（iCKvu）,并据此对参试品种进行了稳定性测定和适应性分析。结果表明：在被测品种中,MA10-9的产糖量和含糖率稳定性较好,具有较广泛的适应性,产糖量水平中等,含糖率水平较低,稳定性较好是该品种的优势。ST13929、Beta807的产糖量和含糖率稳定性一般,二者产糖量和含糖率水平中等,可选择使用。 MA2070的产糖量稳定性一般,含糖率稳定性较好,产糖量和含糖率水平中等,含糖率稳定性较好是该品种的优势。KWS2314的产糖量稳定性一般,含糖率稳定性较差,产糖量水平较高,含糖率水平中等,产糖量水平较高是该品种的优势。 KWS1479、TY309的产糖性状稳定性较差,含糖率稳定性一般：KWS1479产糖量水平较高,含糖率水平一般,产糖量水平较高是该品种的优势；TY309的产糖量水平较低,含糖率水平较高,高含糖性是该品种的优势。 JKF208-10的产糖量和含糖率稳定性较差,产糖量水平较低,含糖率水平较高,高含糖性是该品种的优势。

Adaptability Analysis of the 2013 National Sugarbeet Variety Test

The data from 8 sugarbeet varieties in 15 test sites were analyzed by statistical parameter of LSD value, variance and coefficient of variability from variety, locus and variety × locus in the 2013 National Sugarbeet Variety Test. The results predicated that the variety MA10-9 showed a good productive stability, widespread planting adaptability and common sugar yield and slight low sugar content. The both varieties ST13929 and Beta807 showed an ordinary productive stability of sugar yield and content, ordinary sugar yield and content. The variety MA2070 showed an ordinary productive stability of sugar yield and good productive stability of sugar content, common sugar yield and sugar content. The variety KWS2314 showed an ordinary productive stability of sugar yield and poor productive stability of sugar content, high sugar yield and ordinary sugar content. The both varieties of KWS1479 and TY309 showed a poor productive stability of sugar yield and sugar content;high sugar yield and ordinary sugar content of KWS1479;low sugar yield and high sugar content of TY309. The variety JKF208-10 showed a poor productive stability of sugar yield and sugar content, low sugar yield and high sugar content.
