2015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 2015 National Variety Trial

通过对2015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8个甜菜品种中,品种HI0556、HI1420的产糖性状稳定性较好:品种HI0556的产糖量水平中等,含糖率水平较低,在生产中有一定利用价值;品种HI1420的产糖量水平中等,含糖率水平较高,在生产中有较高的利用价值;品种SV1555、KWS2314、STm1217、STD1244的产糖量稳定性一般:SV1555、KWS2314产糖性状较好,含糖性状亦处中等水平,在生产中有较高的利用价值;STm1217、STD1244产糖性状较差,含糖性状亦处较低水平,利用价值有限。品种Beta468、JKF208-11的产糖量稳定性较差:Beta468的产糖量水平较高,含糖率水平中等,在生产中高产性状应加以利用;JKF208-11产糖量水平较低,含糖率水平较高,高糖性状可选择利用。

The data from 8 sugarbeet varieties were analyzed by statistical parameter of LSD value, variance and coefficient of variability from variety, location and variety × location in the 2015 National Sugarbeet Variety Trial. The results indicated that variety HI0556 and HI1420 have a good productive stability of sugar yield, the variety HI0556 have an ordinary sugar yield and lower sugar content; the variety HI1420 have an ordinary sugar yield and high sugar content. SV1555, KWS2314, STm1217 and STD1244 have an ordinary productive stability of sugar yield. Both SV1555 and KWS2314 have a good sugar yield and ordinary sugar content; both STmI217 and STD1244 have a poor sugar yield and ordinary sugar content. Both Beta468 and JKF208-11 have a poor productive stability of sugar yield, the variety Beta468 has high sugar yield and average sugar content; the variety JKF208-11 has a poor sugar yield and high sugar content.
