Abstract: A study was conducted to evaluate the Protein status of Brown Rice grain in different genotypes at Agricultural College & Research Institute, Thoothukudi districtof Tamil Nadu, India during the period from April 2015 to March 2017. In the present study, twenty different rice varieties inclusive of two traditional cultivars cultivated in and around Thoothukudi district of Tamil Nadu as the test rice grains in the form of Brown rice in completely randomized design with three replications were tried. Screening and evaluation of protein content in 20 rice genotypes were carried out to identify protein rich genotypes. Biochemical research based on five different traits including contents of albumin (Alb), globulin (Glo), prolamin (Pro), glutelin (Glu) and total or gross grain storage protein (GGSP) were carried out. I estimated the relative contribution of Albumin as 0.47 to 1.8 g/100g, globulin as 1.3 to 4.0 g/100g, prolamin as 0.24 to 3.16 g/100g and glutelin as 1.63 to 5.1 g/100g. There was a considerable variation in Gross grain protein contents among Brown rice of twenty cultivars ranged from 6.9 to 9.9 g/100g. Gross grain protein contents were higher in Purple puttu, ASD 16 and ADT 45. The result on status of protein showed that CO (R) 48 had the highest Albumin content. ASD 16 exhibited the highest globulin content. The lowest prolamin content was found in ADT 39, whereas the highest content of glutelin was found in Purple puttu. The overall results of this study revealed that Purple puttu, ADT 39 and ASD 18 were considered as Top three genotypes suitable for Thoothukudi district farmers based on consumer preferences.
