白肋烟品种比较试验研究

为筛选适合云南宾川种植并优质、高产、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：①TN90、KY908、K26株高均高于对照，KY8959、KY907低于对照。各品种单株留叶数除KY907低于对照外，其他都高于对照。各品种大田生育期相差1-3d，属于中晚熟品种。②6个品种在田间均发生角斑病与空胫病，发病率均低于对照，KY8959最低。黑胫病除KY907外，其他均未发病。③供试品种的产量KY907最高，其次是TN90；产值以KY8959最高，其次是KY907。上等烟比例为TN90最高，其次是KY908，其他品品种也高于对照。④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．

Variety Comparison Study on Burley Tobacco

In order to select good quality Burley tobacco varieties, which were appropriate for planting at Binchuan, the field comparison test of 6 induced varieties were conducted and their agricultural and economic characters, disease resistance were analyzed. The results showed： ①The plant height of TN90, KY908, K26 were higher than CK, and KY8959, KY907 were lower than CK. The leaf number of KY907 was lower than CK, and other varieties were higher than CK. Growth period of six varieties has different from 1 d -3 d, which were middle-late maturing variety. ②The resistance data indicated that the tobaccco angular leaf spot and tobacco hollow stalk were found on all varieties, the virus disease incidence of CK was highest, that of KY8959 was lowest among all tested material. Black shank disease of varieties were not found except KY907. ③The economic character analysis indicated that the yield of TN90,, KY8959, KY907 were higher than CK, and KY907 was the highest, and next was TN90 . The output value of KY8959 was the highest, and next was KY907, and the first-class tobacco propor- tion of TN90 was the highest. ④TN90 and KY8959 had better total characteristics so they were consider primarily to be ggood quality Burley tobacco varieties, which appropriated for planting at Binchuan.
