Genetic Variability and Correlation Studies for Yield and Yield Related Traits in Rice (Oryza sativa L.) Genotypes

The present study consist of 29 rice genotypes including one check variety that were evaluated at Field Experimentation Centre the Department Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University Agriculture, Technology Sciences, Prayagraj U.P. to genetic variability, heritability, advance, correlation path coefficient for 13 quantitative characters. experiment was conducted by using Randomized Block Design with three replications during Kharif -2019. Observation recorded variability parameters, yield its attributing traits. Significant reported all On basis mean performance IRRI-156 found be superior in grain per hill followed TP- 30441 NDR-1045. High moderate GCV PCV number spikelets panicle, biological yield, test weight flag leaf length. Grain indicated significant positive days 50% flowering, panicle length, phenotypic level whereas genotypic it showed plant height. Path analysis direct effects on exhibited height panicles effect length level. Thus, these traits are identified as efficient potential indirect selection improvement productivity experimental materials.
