Abstract:

Rice is the world’s second most important cereal crop and staple food for more than 60 per cent of the global population. This paper focuses on morphological characterization using DUS discriptors for seventy five “speciality rices called soft rice genotypes” collected from different parts of north-east Assam. The lines were characterized for 62 agro-morphological traits using DUS discriptors following UPOV guidelines (International Union for the Protection of New Varieties of Plants). The experiment was laid out in a randomized block design with three replications at Directorate of Rice Research Farm, ICRISAT Campus, Patancheru, Hyderabad, India. Among the 75 genotypes, some genotypes were monomorphic, some were bimorphic, some were trimorphic and the remaining genotypes exhibited large variation for some traits. On the whole significant variations were noticed for plant morphological characters, which is useful for each genotype to establish its diagnostic features. This high variability among the rice accessions studied, which presents great importance for breeding programs or for genetic studies on this species. 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 (PPV&FR Act).
