About National Rice Resource Database

NRRD Project is a DBT funded initiative to generate characterization and evaluation data of selected rice germplasm accessions and to develop a user-friendly interface to access such information. National Rice Resource Database is developed based on 15,000 unique rice germplasm (Indigenous-13733, Exotic-1267). These germplasm are characterized for 30 morphological characters —19 qualitative characters (Ligule Shape, Grain Length Width Ratio, Panicle Exertion, Flag Leaf Angle, Leaf Pubescence, Leaf Senescence, Leaf Blade Colour, Early Plant Vigour, Stigma Colour, Apiculus Colour, Threshability, Hull Colour, Panicle Type, Seed Coat Colour, Coleoptile Colour, Basal Leaf Sheath Colour, Awning, Sterile Lemma Colour, Aroma) and 11 quantitative characters (No of Effective Tillers, Days to Maturity, Panicle Length [cm], Plant Height [cm], Auricle Colour, 100 Grain Weight [gm], Seedling Height [cm], Leaf Length [cm], Days to 50% Flowering, Grain Yield Per Plant [gm], Leaf Width[cm]) by five centers (Banaras Hindu University-Varanasi, Central Rice Research Institute-Cuttak, Indira Gandhi Krishi Vishwavidyalaya-Raipur, Central Soil Salinity Research Institute-Karnal and Directorate of Rice Research-Hyderabad) for three seasons (2009-2010, 2010-2011, 2011-2012).

Passport data table is prepared for these unique germplasm to provide information about cultivar and geographical location. A provision to incorporate evaluation traits (Biotic stresses: Gall midge, Stem borer, Brown plant hopper, Blast disease, Bacterial Leaf blight, Brown spot, Sheath blight, Abiotic stresses: Submergence tolerance, Drought tolerance, Salinity tolerance), molecular data, core information, and reference sets, etc. has been made. The project is coordinated by NBPGR, New Delhi.
