【摘要】 在9种不同土壤病害环境中的试验研究结果表明:中甜-吉洮单301根产量平均为46789kg/hm2,分别比单粒生产种HYB-13(CK1)及多粒生产种吉甜301(CK2)增加0.5%及25%;含糖率为17.12%,分别比两对照提高1.98°S及-0.13°S;产糖量为8099kg/hm2,分别比两对照提高11.4%及23%。对环境分解重组进行适应性分析:在沙壤土区、栗钙土区、黑钙土区、根病区、叶病区、无病区6大环境中,该品种的含糖均极显著高于CK1,根产量均极显著高于CK2;在黑钙土区,产糖量与两对照比,增加不显著,在无病区,根产量与CK1比有所降低。经线性回归法分析,除产糖量与CK2比稳定性不显著外,该品种各性状的稳定性均在不同程度上高于两对照。回归直线显示:该品种的根产量、产糖量稳定地高于CK2,含糖率稳定地高于CK1。更多还原

【Abstract】 The test results in 9 different soil -disease environments showed:The mean root yield,sugar content,sugsr yield of Jitao mono301 reached 46789kg/hm2,17.12%,8099kg/hm2,and were over HYB-13(monogerm,CK1)by 0.5%,1.98°S,11.4% and over Jitian(multigerm,CK2)by 25%,-0.13°S,23%respectively.Adoptabiliy analysis results from each big environment types indicated that:Its sugar content was over CK1 and root yield was over CK2 very significantly in sandy loam,chestnut soil,carbonat black earth,Rhizomania regin,cercospora leaf spot region,non-diserse region.Its sugar yiled was over two CK by a little margin in carbonat black earth and its root yield was lower than CK1 in non-diserse region.The linear regression analysis result indicated that:The stability of all the its characters were over two CK by a different margin.Regression straight line showed:Its sugar content value was over CK1 and root yiled,sugar yiled were over CK2 stably in the whole environment.更多还原
