Genetic Variability and Character Association for Grain Yield Components in Maize (Zea mays L.)

The present investigation was carried out to assess the genetic variability parameters, correlation and path analysis in twenty-one maize genotypes for sixteen quantitative traits Kharif seasons at Field Experimentation Centre, Department of Genetics Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University Agriculture Technology Sciences, Uttar Pradesh Randomized Block Design replicated thrice. Analysis variance all characters revealed that treatment differences were highly significant under study 1% level season. objective oriented calculate estimate yield through analyzing mean performance, variability, expected advance, coefficient involving attributing characters. Among 21 genotypes, BML-13 (109.67), MGW-376 (108.93) found be superior grain per plant over check (Shaktiman-5). GCV less than PCV, indicating influence environmental component on expression character. High heritability coupled with high advance as percent recorded height, ear rows cob, cob weight, biological plant, 100 plant. Path Correlation length, girth, grains row, number cobs weight had positive direct effects Therefore, it is concluded effective selection must attempted these which would help improvement genotypes.
