适应寻甸烟区种植的烤烟新品系试验研究

Research on Experiment of Planting New Flue-cured Tobacco Varieties Adapted to the Ecological Environment of Xundian County

2014年在昆明市寻甸县试点,以MSK326为对照,针对中国烟草育种研究(南方)中心提供的6个烤烟新品系开展小区品比试验.结果表明,田间抗病性、经济性状、外观质量等综合表现以云烟120和云烟207较好,NC-YATAS-1、云烟209、NC-YATAS-6中等,云烟208较差.而根据田间生物学数量性状,可将6个新品系分为3类:第1类(云烟207)营养生长期长,植株高、叶数多、茎秆细,移栽至现蕾、中心花开放期的时间明显推迟;第2类(包括云烟208、云烟209和NC-YATAS-6)叶数少,移栽至现蕾、中心花开放的时间中等;第3类(包括NC-YATAS-1、云烟120和MSK326)株高、叶数和节距中等,叶片较窄,移栽至现蕾、中心花开放的时间较短.

To provide reference basis for approving tobacco varieties and regional planting, in 2014, taking the local spreading variety MSK326 as the contrast, 6 new flue-cured tobacco varieties coming from China Tobacco Breeding Research （Southern） Center were tested in Xundian county. The results showed that according to the comprehensive analysis in aspect of diseases occurrence in the field, economic traits, and appearance quality of initial cured leaves, Yunyan 120 and Yunyan 207 were the best; NC-YATAS-1, NC-YATAS-6 and Yunyan 209 were better; Yunyan 208 was the worst in all the indexes compared to the contrast. According to biological quantitative traits, 6 tobacco varieties could be divided into three categories. The first class Yunyan 207 showed long nutrition growing period, high plant height, mord leaf number, and thin stem and the obvious delayed time from transplanting to bud presenting and blooming. The second class Yunyan 208, Yunyan 209 and NC-YATAS-6 showed less leaf number and the medium time period from transplanting to bud presenting and blooming. The third class NC-YATAS-1 , Yunyanl20 and MSK326 showed that medium plant height, leaf number and pitches, narrow leaf shape and short time period from transplanting to bud presenting and blooming.
