摘要: 为筛选出适合云南宾川种植并达到优质、适产、抗性好的品种,对6个白肋烟品种进行了田间比较试验。结果表明:(1)品种TN90、KY907、KY8959、长势较强,5个品种的株高均高于对照。各品种单株留叶数都低于对照,以KY8959最高,KY908最低,其它品种间差异不大。各品种大田生育期差异不大,属中晚熟品种。(2)各品种发病率均较低,Va1061、KY8959、TN90的TMV、黑胫病发病率比CK低,KY907、VA1061、TN90赤星病发病率稍高。(3)供试品种的比叶重下部叶以KY907最重为3.421mg/cm2,中部、上部叶均以KY8969为重,分别为4.427mg/cm2、7.645mg/cm2。三部位平均值以KY8959居首,比CK重4.02mg/cm2,其次是TN90为4.762mg/cm2,比CK重0.134mg/cm2,其它品种均低于CK。(4)产量KY908最高,其次是CK与KY8959;产值是CK最高,其次是KY907;上等烟比例TN90最高。(5)农艺性状、抗病性、经济性状综合比较,TN90、KY8959较适宜在云南宾川与对照TN86同时进行小规模种植示范

Abstract: In order to select quality Burley tobacco varieties, which were appropriate for planting at Baoshan, the field comparison test of 6 introduced varieties were conducted and their agricultural and economic character, disease resistance were analyzed. The agricultural character results showed that the plant height of 5 varieties was higher than that of CK. The leaf number of all the varieties was lower than that of CK, and that of the KY8959 was the highest and Ky908 was the lowest. The growing stage of all varieties had no significant different, which were middle-late maturing variety. The resistance date indicated that disease incidence of Va1061, KY8959, TN90 of the tobacco mosaic virus and tobacco black shank disease was lower than that of CK, and the disease incidence of brown spot of Va1061, KY8959, TN90 was higher. The specific leaf gravity of KY907 was the heaviest in all the lower leaf of varieties, which was 3.421mg/cm2. The specific leaf gravity of KY8959 was the heaviest in all the cutters, upper leaf of varieties, which was respectively 4.427 mg/cm2、7.645mg/cm2. The average specific leaf gravity of Ky8959 was the heaviest. The yield of KY908 was the highest, and that of CK and KY8959 was second. The output value of CK was the highest, and that of KY907 was second, and the first-class tobacco proportion of TN90 was the highest. TN90, KY8959 had better total characteristics, so they were considered primarily to be quality Burley tobacco varieties, which appropriated for planting in Baoshan.
