Genetic parameters of variation for yield and its components under saline and normal environments in wheat (Triticum aestivum L. Em. Thell.)

High PCV and GCV were recorded for the characters effective tillers per plant, grains per ear, grain yield per ear and grain yield per plant in all the four environments. High heritability along with high estimatei of genetic advance as percentage of mean were recorded for the characters plant height and grain yield per ear under both the saline environments (E₁ and E₃ while for the characters effective tillers per plant, grains per ear and grain yield per plant under both the normal environments (E₂ and E₄).
