This study was conducted at Plant Growth Center of Montana State University in 2011. Experimental design was “in completely randomized design” with four replications. Varieties with different average plant heights (Yellowstone, 87.9 cm; CDC Falcon, 78.5 cm) were determined in 30 locations of Montana State during 2007-2011. Seedlings subjected to vernalization during 7 weeks were planted to higher pots (50 cm), which were filled by mixing of peat (70%) and perlite (30%). Plants were harvested in 22-24, 69 and 92 growth stages of wheat (Zadoks Scale). Results of this study showed that dry root weight increased by GS 69 but, decreased 39.8 % in CDC Falcon and 13 % in Yellowstone from GS 69 to 92. Dry root weight in GS 69 and 92 of Yellowstone was greater than CDC Falcon. Increase and change in dry root weight have increased yield and yield components of Yellowstone compared to CDC Falcon. Dry root weight significantly increased when plant height increased.
