DUS Characterization for Farmer varieties of rice

Abstract

For the establishment of the distinctness among Sixty-five landraces of rice, forty three characters were used. Characterization of Sixty-five landraces of rice was done using forty three agro-morphological traits following Distinctiveness, Uniformity and Stability test (DUS) during kharif season of 2011 at the DRR farm, ICRISAT campus. Out of Sixty-five varieties studied, thirty-two were found to be distinctive on the basis of twenty two essential and twenty four additional characters. This study will be useful for breeders, researchers and farmers to identify and choose the restoration and conservation of beneficial genes for crop improvement and also to seek protection under Protection of Plant Varieties and Farmer's Rights Act.
