The present investigation was carried out to assess the variability, heritability and genetic advance in fourty two maize genotypes for twelve yield and its contributing traits. The analysis of variance revealed the presence of significant variability among the maize genotypes under study. Among all the characters under study, ear eight exhibited highest PCV (27.52) and GCV (26.42), whereas lowest PCV (3.45) and GCV (3.07) were recorded for days to maturity. Ear height and grain yield/plant expressed high heritability coupled with high genetic advance, which indicated the preponderance of additive gene action in controlling the traits. Hence direct selection of such characters would be effective in improving the yield. Emphasis should be given on these characters, while selection to improve yield potential of crop.
