2014年国家甜菜品种区域试验品种稳定性评价

Evaluation of Productivity Stability of New Sugarbeet Variety in the 2014 National Variety Trial

通过对2014年国家甜菜品种区域试验部分品种试验结果的统计分析,求得品种×地点互作效应值(VU)ij、变异系数(i CKvu),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:在被测的12个甜菜品种中,ST21115、STD1210的产糖量和含糖率稳定性较好,具有较广泛的适应性,产糖量和含糖率水平中等,这两个品种有较好的利用价值。KWS1197、STm0915的产糖量稳定性较好,含糖率稳定性一般:KWS1197产糖量和含糖率水平较高,有较好的利用价值;STm0915产糖量和含糖率水平中等,也有较好的使用价值。SV1434、Beta240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一般,有较好的利用价值。ST12024的产糖量和含糖率稳定性一般,产糖量和含糖率水平较高,该品种有较好的使用价值。ST1213的产糖量稳定性一般,含糖率稳定性较差,产糖量和含糖率水平较低,该品种的利用价值有限。SV1433的产糖量稳定性较差,含糖率稳定性一般,产糖量和含糖率水平较高,该品种可在适应地区选择使用。STN1323、STm7117、HDTY16的产糖量和含糖率稳定性较差;HDTY16的产糖量水平较低,含糖率水平较高,高含糖性状可选择利用;STN1323、STm7117产糖量和含糖率水平较低,二者的利用价值有限。

The data from 12 sugarbeet varieties were analyzed by statistical parameter of LSD value, variance and coefficient of variability from variety, location and variety x location in the 2014 National Sugarbeet Variety Trial. The results indicate that variety ST21115 and STD1210 have a good productive stability and wide planting adaptability of sugar yield and sugar content, with average sugar content and sugar yield. Both KWSl197 and STm0915 have a good productive stability of sugar yield, and an ordinary productive stability of sugar content; KWS1197 has high sugar yield and sugar content; STm0915 has average sugar yield and sugar content. SV1434 and Beta240 have an ordinary productive stability of sugar yield, and good productive stability of sugar content, with average sugar yield and sugar content. ST12024 has an ordinary productive stability of sugar yield and sugar content, with high sugar yield and sugar content. The variety SV1433 has a poor productive stability of sugar yield and ordinary productive stability of sugar content, with high sugar yield content and sugar content. STN1323 and STm7117 have a low sugar yield and sugar content.
