Abstract:
Wheat is an essential crop which is cultivated across the globe, and consumed by a substantial proportion of the human population. There is huge need to increase the yield and productivity of the wheat for feeding the exponentially expanding human population. So the recent research was aimed to analyse the genetic variability, broad sense heritability, and genetic advance on yield and its associated traits. It was carried out on 100 different wheat genotypes which included 4 checks, in the experimental fields of Lovely Professional University in an augmented design. ANOVA demonstrated a significant difference among the studied genotypes for the traits under investigation. High genotypic and phenotypic coefficients of variation were noticed in the traits number of productive tillers per plant, and plot yield per genotype, while moderate GCV coupled with PCV were noticed for traits thousand grain weight, grain yield per plant, biological yield per plant, and harvest index. Heritability was higher for all traits, while higher heritability along with higher genetic advance over percent mean was found for traits viz., number of productive tillers per plant, thousand grain weight, plot yield per genotype, grain yield per plant, biological yield per plant and harvest index. So the traits number of productive tillers per plant, thousand grain weight, plot yield/genotype, grain yield/plant, biological yield/plant and harvest index can be chosen in breeding programs as they can be inherited into the off springs easily.
