Abstract: In order to select quality Burley tobacco varieties, which were appropriate for planting at different production district, the field comparison test of 7 selected varieties were conducted and their agricultural and economic character, disease resistance were analysized. The agricultural character results showed that the plant height were higher than that of CK besides B6, B7.The plant height of B2 was the highest. The leaf number of 7 varieties were average 21.31 respectively, which were less than that of CK. The growing stage of all varieties had no significant different, which were middle maturing variety. The disease index of B2, B5 for TMV were 41.07and 31.70, and resistance of them was MR. The disease incidence B6 black shank was highest in the rosette stage,and the disease incidence B7 black shank was highest in the mature stage. The first-class tobacco proportion of B5 was highest. The yield of B1 was highest, and was bigger than that of CK. The yield of B5, B3 was second and third respectively. The output value of B5 was the highest .B3,B1 had better total characteristics so were consider primarily to be quality Burley tobacco varieties, which appropriated for planting at BinChuan.
