Traditional rice varieties (TRVs) collected from different locations of Karnataka were evaluated for grain yield, its attributes, reaction to blast, grain quality and cooking parameters (protein, amylose, iron and zinc content using NIR) by adopting standard procedures. Analysis of grain nutrient contents such as protein, amylose, iron and zinc revealed wide variation for the grain protein content (5.57-14.96%), amylose (17.25-44.42 %), iron (9.17-15.72 mg/kg) and zinc (10.24-33.40 mg/kg). Physical, physico-chemical and cooking quality parameters estimated for the selected 49 TRVs also indicated significant difference for water uptake ratio suggesting variation for kernel texture, surface area and amylose content. Screening of theTRVs for field resistance against leaf blast disease revealed that 11 out of 324 TRVs were found resistant at both Mandya and Ponnampet. Molecular validation for leaf blast disease resistance for selected TRVs revealed that, Pi 9 resistance type allele present in 48 TRVs; Pish in 42; Pi38 in 46; Pib in 28; Pi 20(t) in 26 and PiK in 21 TRVs. © 2014, Indian Society of Genetics and Plant Breeding.
