【摘要】 甜菜新品种中甜─吉洮单一由洮育单粒二倍体品系85─724与多粒二倍体品系A2－1046杂交育成，属标准偏高糖单粒型新品种，其双亲配合力高，杂种优势强。该品种在吉林省甜菜品种区域试验及生产试验中，其根产量、含糖率和产糖量比单粒对照品种吉甜单一提高5．9％～12．2％，1．9～1．1度，19．2％～19．6％；比偏高糖多粒对照品种范育一号提高1．83％～39．0％，（─0．6）～（─0．7）度，13．6％～34．0％。在黑龙江、山西、宁夏、新疆等五省异地鉴定中根产量、含糖率、产糖量分别比当地多粒对照品种提高4.3％～43．4％，（─0.3）～1．3度，115％～48．1％。该品种高抗褐斑病，多点调查结果是，其褐斑病发病级数比省内对照品种低一级左右，比省外多粒生产种低0．3～1．4级，比国外抗病生产种低0．3级，比国外感病生产种低2．7级。更多还原

【Abstract】 Jitao Dan 1 was bred by crossing sugarbeet monogerm diploid line 85-724 with multigerm diploid line A, - 1046. Its ecnomic character belonged to the N-type and with higher sugar content in sugarbeet monogerm varieties Its parents are lines with higher combining ability and the variety is in itself a hybrid with higher heterotic vigar. The average root yield,sugar content and sugar yield of this variety was over the variety Jitian Dan 1 (CK) with 5. 9 %~ 12. 2 %, 1.9 ~ 1.1S°, 19. 2 % ~ 19. 6 % in Jilin province sugarbeet varieties trial and production domonstration. Its cercospera resistance was over the Jitian Danl,HYB- 13CR,some external susceptible varieties with 1.0, 0.3 and 2. 7 grade respectively at some trial places in Jilin province.更多还原
