Abstract

This study was carried out to obtain the basic information about the sucker producing characteristics of certain burley tobacco varieties(Nicotiana tabacum L. var. burley) at Suwon and Chonju Experiment Station, Korea Ginseng & Tobacco Research Institute in 1999. The number and weight of suckers for 12 varieties or breeding lines were investigated three times, 45 days after transplanting for ground sucker, 10 days after topping, and 10 days after maleic hydrazide(MH) applying for upstalk sucker. KB 103 and KB 9416-1 produced less ground suckers and upstalk suckers than other entries did. KB 9210-8 produced less ground suckers and (Male sterile TC 612 x KB 108)F$_1$ also produced less upstalk suckers than other entries did. There was no differences among entries in sucker production at 10 days after MH treatment. Between the weight of total sucker and days to flower revealed the negative correlation, but not significant. The low sucker producing entries described above could be used as a parental line in the breeding program for the low sucker producing variety.
