甜菜品种适应性鉴定分析

在新疆两个最主要的甜菜产区南疆的焉耆和北疆的伊犁4个县市进行3个甜菜品种适应性生产试验,结果显示,KWS7125在4个点块根产量74.88～101.96t/hm2,变化幅度在17％以内,比较稳定;含糖14.58％～16.53％,含糖比较高,变化幅度在1.00度内,比较稳定;该品种在不同地区块根产量和含糖都比较高、变动幅度较小,说明对不同地区适应性较强,综合表现很突出.KWS0143块根产量85.86～89.21t/hm2,变化幅度1.9％,变动非常小;含糖13.90％～14.80％,变化幅度在0.50度之内,变化非常小;该品种生长势强,丰产性好,抗病性强,适应性很好,表现很稳定,是一个很稳定的优良品种.KWS2409是新疆种植面积最大的主栽品种,是新疆甜菜区试的对照品种,在4个点块根产量77.22～106.81t/hm2,变化幅度17％,其含糖13.41％～15.74％,变化幅度在1.20度,变动幅度比较大;该品种丰产性突出,但在不同地区块根产量和舍糖变动幅度较大,不同地区适应性并不突出.
