Abstract: Experiment was conducted under assured rainfall conditions to test four rice genotypes against National (Sabita), Regional (Purnendu) and local (Asha) check varieties for their 50 % flowering, plant height, panicle length, grain yield and straw yield Kg ha^-1, during 2010, 2011 and 2012 Kharif season to identify the suitable genotype for the region.50 per cent flowering differed significantly among genotypes tested maximum days taken for 50 % flowering was recorded in Asha 141.3 days in 2011, 113.5 days in IET 21341 during 2012. During 2012, 50 % flowering was found to be highest 113.5 in IET 21341. Plant height showed significant difference among genotypes is all three years. Maximum plant height of 130.6, 144.3 and 107.6 was recorded in IET 21347, Purnendu and Sabita during 2010, 2011 and 2012 respectively. Panicle length differed significantly among genotypes in all three tested years, maximum panicle length of 25.3, 26.9 and 24.3 cm was recorded in Purnendu, Asha and Purnendu during 2010. 2011 and 2012 respectively. Number of panicles per square meter found to be differed significantly among genotypes during 2010. Maximum number of panicles recorded in IET 21347 (266) followed by Sabita (245).Grain yield varied significantly among genotypes in all three years of test. Maximum grain yield of 8280, 6074 and 5947 Kg ha^-1 recorded in IET 21341, Purnendu and IET 21347 during 2010, 2011 and 2012 respectively. Straw yield different significantly among genotypes tested all three years. Maximum straw yield of 22980 and 19614 Kg ha^-1 was recorded in Sabita and Purnendu during the year 2010 and 2011 respectively. Highest hulling and milling percentage, was recorded in IET 21347 (80.5 % and 72.8 %), moderate ASV with 22.59 % AC and 25 mm GC. Both the genotypes viz., IET 21341 and 21347 were showed significantly superiority over checks with desirable quality parameters, may be recommended for the farmers under shallow low land situation of Uttara Kannada district of Karnataka State.
