Abstract:

In order to select good quality tobacco varieties, which were appropriate for planting at Xiangxi, the field comparison test of 7 induced varieties were conducted and their agricultural and economic characters, disease resistance were analyzed. Results showed, (1) there was no obvious difference between botanical characters of varieties in growth duration. (2) The plant height of ‘ZY-201’, ‘HY-9-7’ were highest, and stem diameter and pitch of ‘ZY-201’, ‘GY-4’ were higher than CK. (3) The incidence of tobacco disease on ZY-201 was the lower, and ‘KRK26’, CK was the highest. (4) The economic character analysis indicated that the yield of ‘GY-4’ was the highest, and the next was ‘ZY-201’. Therefore, ‘ZY-201’, ‘GY-4’ had better total characteristics, which were appropriated for planting at Xiangxi.
