Abstract :

This plan detection target of on rate tolerance to welter in condition none water to experimental   epilate stripe plat  with tree replicates  in 2011-2012 years in Damghan  city and Index welter Sensitivity, tolerance Index, Stress tolerance Index,(GMP),(MP). Result shows that with been types proud action grain variation significant (P<0/05). In condition without stress Types 33 with 4790 kg. ha maximum production and also in stress condition type 33 wit been 2645 hg production maximum and maximum Index rate (STI) in top stress depended type. 33 type shows Maximum (MPL) (GMP) and calculation correlation index with production in normal condition and stress shows that production in stress condition YS related significant with (YP) and Index Totally except  sensitivity index in (SSI) and correlation (YP) With STI,MP,GMP, TOL significant correlation between MP with STI with GMP,STI with GMP positive significant and shows maximum correlation between MP,GMP,SSI shows related negative and non significant result In experimental shows the Index STI. MP, GMP, Index good for estimation production.
