Genetic variation in segregating generations of F5 and F6 in rice (Oryza sativa L.) for grain protein content (GPC), seed nutrient and yield

Abstract: Protein is an important component in human nutrition and is superior in lysine content than wheat, corn and sorghum (Hegsted, 1969) in rice (Oryza sativa L). Present investigation was carried out to increase total grain protein (TGP) content in rice using two diverse parents viz., BPT – 5204 (fine grain with low protein) and HPR – 14 (bold grain with high protein). In F5, protein was ranged from 7.10 to 18.06 percent, however it was decreased in F6 (8.15 to 12.92%). The wide range indicates that the alleles are segregating the traits under consideration and stabilizing in F6. The other quality (grain length, grain width, grain length to breadth ratio, kernel length, kernel breadth, and kernel length to breadth ratio), nutrients (nitrogen, phosphorous, potassium, zinc, manganese, copper and iron), yield and yield attributing (days to flowering, days to maturity, biomass, number of tillers, number of panicles, panicle length, seed fertility percentage, grain yield, test weight and harvest index) parameters also recorded the same trend as TGP.
