作者利用直线回归统计分析方法,对1981—1983年甜菜区域化试验结果,进行了品种适应性、稳定性分析。认为,品种科研301、双丰304单产较高,适应性较大。甜研301含糖率、产糖量表现了相对的稳定,适应性广;双丰304含糖偏低,故二品种应控制在高糖地区使用。7613属于标准偏高糖型品种,单产、含糖率、产糖量稳定,可在一定地区推广使用,7807、7805含糖率较高,单产偏低,且均稳定,可考虑在高产地区使用。
Using the method of linear regression statistical analysis, the authors analyzed the adaptability and stability of the sugar beet regionalization in 1981-1983. That the variety of research 301, Shuangfeng 304 yield higher adaptability. Sweet study 301 sugar content, sugar yield showed a relatively stable, wide adaptability; Shuangfeng 304 low sugar, so the two varieties should be controlled in high sugar use. 7613 belong to the standard high sugar type varieties, yield, sugar content, sugar yield stable, can promote the use of certain areas, 7807,7805 higher sugar content, yield is low, and are stable, can be considered in high-yield areas .
