Canola is a new crap and valuable for supplies plant oils and suitable for using in crop. Given the importance of it’s planting as an oilseed and given this issue that Iran is one of the world’s arid and semiarid regions. Recognize of genotypes that can tolerate drought stress at different stages of growth. This issue will be effective in increase of plant density in field and ultimately in more yield.This experiment 10 number of canola genotypes, in factorial experiment on block design with 3 repetition of drought tolerance and Incubator temperature differences in various classes as block in laboratory of guilan agriculture school was evaluated at (2013/10/23). The achieved results of cluster analysis method between groups after selecting most appropriate cut line show that they divided to 3 groups in potential of 4 MPa and they divided to 2 groups in potential of 8 MPa and they divided to 3 groups in potential of 12 MPa too. The achieved results divided genotypes for 4 level stress and analysis of detect function showed classification accuracy to 95% after that drawing of most suitable cut line.
