Abstract

The expertise of agro-morphological variability within a crop and its dispersion across agro-ecological areas may be very useful in managing the crop's germplasm and developing improved methods. Crop failure is guarded against through genetic variety. However, dwindling genetic wealth erodes the capacity to maintain and enhance agricultural productivity. West Bengal has rich rice genetic wealth. But this genetic wealth is being silently depleted due to the onslaught of the high-yielding varieties (HYVs) and neglect The 10 traditional rice varieties were collected from the Cooch Behar district of West Bengal, India. The present study aimed to characterize the rice genotypes using agronomic characters. The assessment was done following the Standard Evaluation System (SES) for rice developed by the International Rice Research Institute. Even though all the ten local rice varieties were adapted to the Cooch Behar district, a fair amount of diversity was found among the rice genotypes.
