Aman rice, a major cereal crop in Bangladesh, frequently encounters monsoon and late floods during the vegetative growth period in August-September. The crop cannot withstand if the flood water remains stagnant for more than 4 to 5 days. In this context, a variety named BRRI dhan52 evolved to grow in 2 to 3 weeks of submergence without losing significant yield. However, no systematic study has yet been ‘made regarding the performance of BRRI dhan52 in real situations. Thus, farmers’ perceived performance has been focused on the study, which was estimated based on responses against 30 different flood tolerant characteristics of BRRI dhan52 in a four-point scale of measurement. Findings reveal that the highest proportion (63.1 percent) of the farmers had moderately favorable perceptions, followed by 19.4 percent with low favorable perceptions and 17.5 percent with high favorable perceptions towards all the 30 characteristics. Out of which, the top five were: can tolerate sudden flood (PI=285), less photosensitive (P1=284), lodging tolerant (PT=284), produce more straw and more fodder (PI=283). Considering the mean values of PI it was found that the complexity related to the use of BRRI dhan52 technology was highly perceived as reflected by PI= 218, followed closely by compatibility of 215, trial ability by 206, relative advantage by 177, and operability by 172. It is also observed that education, family size, communication media, and attitude towards BRRI dhan52 showed significant positive relationship with their perception.
