牡丹江地区晒烟新品种(系)比较试验初报

Comparative Experiments of New Sun-cured Tobacco Variety(Lines) in Mudanjiang

为加快选育适宜当地种植、株型好、优质、抗病、高产的晒烟新品种进程,2011年采用完全随机区组试验设计,以‘龙烟2号’为对照,对收集、引进的4个新品种‘星子’、‘东风1号’、‘农安窄叶’、‘农安宽叶’及选育的新品系‘牡晒9712’进行比较试验。结果表明,‘牡晒9712’茎叶角度小、株型理想、抗赤星病,产量3331.40kg/hm2,收益34113.54元/hm2,与对照‘龙烟2号’达到显著水平和极显著水平;‘星子’赤星病病情指数为1.44,抗性为高抗,产量较对照增产13.6%,收益较对照增收17.3%。因此可初步得出‘星子’、‘牡晒9712’是适宜当地种植的优良品种(系)。‘东风1号’、‘农安窄叶’高抗赤星病,可考虑作为杂交亲本。

Speeding up the breeding process on good plant type,excellent quality,strong disease resistance,high yield of sun-cured tobacco varieties for suitable local cultivation.The＇Longyan 2＇was in control,tobacco varieties＇Xingzi＇,＇Dongfeng 1＇,＇Nong＇an narrow leaf＇,＇Nong＇an broad leaf＇and＇Muxi 9712＇ were selected for comparative experiment.The results revealed that：smaller leaf angle,ideal plant type and resistant red star disease in＇Muxi 9712＇with output 3331.40 kg/hm2,reached to the significance level,income reached extremely significant level.＇Xingzi＇was that high resistance of disease index of red star in 1.44,yield increased by 15% and income increased by 17.3%.Therefore＇Xingzi＇,＇Muxi 9712＇were suitable for locally grown varieties.＇Dongfeng 1＇,＇Nong＇an narrow leaf＇having higher disease resistance,could be considered as crossing parents.
