Abstract: Flash floods are a recurrent phenomenon in the North Bank Plains Zone (NBPZ) of Assam, India, causing wide spread damage to rice (Oryza sativa L.) crop growing during Kharif season. Therefore, it is imperative to identify indigenous technical knowledge and integrate this with mainstream technologies, Maguri and not only to enable more effective ways of coping with such extreme events but also to enhance the adaptive capacity of small-scale local farmers of the NBPZ. Identifying and evaluating traditional crop varieties in the NBPZ that are flood tolerant is one approach that may help manage weather hazards and build climate resilient agricultural systems. This research represents investigations on more flood-resistant local rice varieties. In 2013 and 2014, participatory on-farm trials were conducted in Ganakdolonivillage, a community in NBPZ affected by flash floods. Thirty sites covering 20 ha were selected to evaluate the performance of five traditional floating rice (bao)varieties: Kekua, Tulshi, Dhushuri, Bahadur Rangabao. In both the years, the rice fields were affected by flooding multiple times, to a depth of up to 173 cm. The rice varieties recommended for normal, submergence and deep water situations could not perform well and were damaged extensively. The traditional rice varieties generally growing in deep water situations, however, endured the flash floods, performing better and producing grain yields from 1628 to 3000 kg ha-1. Amongst these traditional varieties, Dhushuri recorded the highest grain yield in both the years.
