In order assessment of suitability and stability operation hybrid of mail sterile internal flue- cured tobacco with Coker347 as control were compared. The design of the experiment was Randomized complete block (RCBD) with three replications,in three field in talesh area in two years.The seedlings prepared in Rasht tobacco research center. After plantling the seedlings fertilizing, irrigation and campaign against pests and disease has don on time. Ripe leaves harvested and cured on bulk curing and assessmented by one of the assessor expert. for doing test of being normal of data distribution for all traits in two years separately Excel,SAS and Mstatc soft ware were used also for determining interaction of year with variety and determining of the best variety for two years , experiments of two years compound analysis was done.

Results of variance analysis of two years separately indicated the significant-differences between treatments on 1% level, study. Of corresponding interaction of year on variety showed that there in is no significant difference between treatments. Comparison of treatments means by tukey method showed that varieties ULT138 with4133kg and 72240677Ria1, PVH19 with 3444kg, and 68740266Ria1, NC100 With3642kg and 65864790Ria1 had the highest weight of cured leaf and income per hectare respectively therefore ULT138 is the higher variety.
