The research was conducted to the Department of Genetics and Plant Breeding, Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur during Boro season in 2010-2011 and some selected characteristics were analyzed and compared. Different characters were being pointed which might responsible for drought tolerance in rice. In this study four Bangladeshi rice varieties (BRRI Dhan28, Zirasail, Parizat and Hobigonj Boro6) were characterized and compare with the African drought tolerance rice variety Nerica-4 to find out the possible variety for drought resistant variety development. It was found that root thickness was associated with drought tolerance ability of rice. Among the Bangladeshi rice variety, Parizat had the higher thickness indicating the high drought tolerance ability. It was also found that moderate plant height with thicker root can be considered as drought resistant variety. So, breeding of Parizat with Nerica-4 might give the desirable drought resistant variety.
