Varietal Identification of Four Rice Varieties from Chhattisgarh through DUS Characterization

Abstract

Rice is an important food crop in India and highest
number of rice varieties have been released in India,
among crop species, to cater the needs of the farmers
and consumers. Assessment of genetic variation is an
essential component in genotypes characterization and
conservation. Continued usage of morphological data to
describe cultivars indicates that these retain popularity
in descriptors till date (Pauksens, 1975). Morphological
descriptors provide unique identification of cultivated
varieties but they not only reflect the genetic constitution
of the cultivar but also the environmental interaction
within which it is expressed
