Assessment of Genetic Variability, Cause and Effect Inter-relationship among Yield Component Characters in Maize (Zea mays L.)

The present investigation was carried out to assess genetic variability parameters, correlation coefficient analysis, path analysis in 21 maize genotypes for 15 quantitative traits viz Days 50% tasseling, silking, anthesis – silking interval, 75% maturity, Plant height (cm), Ear Cob length girth weight (g), Number of grain rows per cob, grains row, 100 Biological yield plant Harvest index (%), Grain (g) Randomized Block Design with three replications Kharif season 2022 experimentation field, Department Genetics and Breeding, Naini Agricultural Institute, Sam Higginbottom University Of Agriculture, Technology Sciences, Prayagraj. Analysis Variance revealed that high significant differences among the all traits. Genotypes VL 19458, 19457, 183879, 19453 had depicted higher plant. All characters expressed moderate estimates heritability. GCV PCV investigations a level variation impact environment exhibiting these positively significantly associated at both genotypic phenotypic levels, according between attributing In Phenotypic Genotypic Path detailed diagonal values show positive direct effect on
