Comparative Analysis of Traditional Scented Rice (Oryza sativa L.) Varieties under Organic Cultivation Based on DUS Testing and Yield Assessment

An agricultural field study was conducted during the kharif season of 2020 at the G.B. Pant University of Agriculture and Technology in Uttarakhand, India, to investigate the qualitative and quantitative attributes of traditionally scented rice cultivated through organic methods. The experiment, a randomized block design with three replications, evaluated ten rice varieties, labeled as V1 to V10 (Kubir Mamhani, Kudrat-5, etc). The morphological variations among the varieties (registered under PPV&FR Act 2001) are based on DUS (Distinctness, Uniformity, and Stability) is required for protecting the uniqueness of traditional scented varieties of rice. It can also be the indicative of the yield. The grain, straw and harvest index were found the highest with variety Kudrat-5 followed by Kudrat-1.
