بررسی صفات کمی و کیفی ارقام و لاینهای گندم زمستانه و نیمه زمستانه در آزمایشات بین المللی مقایسه عملکرد سال زراعی ‮‭81-82‬

For obtaining the high yield potential with high stress tolerance and desirable agronomic charactcrs and idcntifying tbe desirable genes of bread wheat varieties this. project was done with 4 experimcnts as follows: " 1- 7th EYT(2002-2003) : This experiment was done with 25 lines! varieties of bread wheat received from Turkey CIMMYT, using a randomized complete block design with 2 replication in Ardabil region. The results Showed there was Significant differences between studied of bread wheat lines! varieties so, 2 high yield potential, diseases resistance and stress tolerant varieties! Lines for evaluating ill future experiment were selected. 2- 12" FA WWON (2002-2003) :This experiment was studied with 200 winter and facultative bread wheal lines! varieties that received from CIMMYT of Turkey using a unrcpliculed experiment the mentioned varieties were evaluated. So the 18 winter- facultative lines! vari.etics with high stress tolerance and desirable agronomic characters and producing more grain yield than local check such as Shahriar and Gaspard ,were selected.The selected lines/varieties will study in advance experiments of future year. 3_6th WON-IR (2002-2003): This experiment was done with 50 winter wheat lines/ varieties that received from CIMMYT of Turkey using a unreplicated experiment. The mcntioned varieties were evaluated and the 17 high stress tolerance and desirable agronomic characters and producing more grain yield than local check such as C-73-20, Gaspard, ZmTin and Alvand were selected and selected lines/varieties will study ill future advance yield Trials of next year. 4- 51h WWEER YT (2002-2003) :64 Lines! varieties of winter wheat with Shahriar as local check using a equal lattice design with 3 replication during winter growing season (October to July) in Ardabil region were evaluated. Data from this experiment were analyzed und 2 high yield potential with best agronomic characters and stress tolerant I incs were selected
