Indigenous rice landraces are an invaluable resource for restoring genetic diversity. Precise biochemical profiling based on protein banding provides information about the extent of genetic diversity, which helps for effective breeding programs. The present study evaluated SDS-PAGE protein profiling of selected six indigenous rice genotypes from Koraput along with tolerant (N22) and susceptible (IR64) check varieties under control and simulated drought stress. A total of 50 polypeptide bands ranging from 47.7 kDa to 200 kDa were harvested from studied rice genotypes under drought stress, whereas 47 polypeptides bands ranging from 47.13 to 200 kDa was observed in control plants. A total of 17 unique bands were noticed under drought-treated plants, which were absent in control plants. The number of protein bands were higher in some indigenous rice landraces than that of drought-tolerant and susceptible check variety under drought stress. Based on the genetic similarity analysis, some indigenous rice landraces such as Machhakanta, Haladichudi and Kalajeera showed highest genetic similarity with drought tolerant check (N22) variety and formed one cluster. The presence of some unique protein bands in these genotypes indicates their importance for drought tolerance breeding and can be further used for ‘omic’ studies to better understand stress responses.
