Abstract
The present experiment was conducted at Barley and Wheat Research Institute, ARI, Tandojam during 2016-2017 in order to study the inheritance pattern of various agronomic traits in nine F2 segregating populations of bread wheat including nine parents and their six F2 progenies for nine morphological attributes. The mean squares of genotypes for all the traits were significantly different (P ≤ 0.05), while mean squares for majority of the traits were also highly significantly different (P ≤ 0.05) in parents except tillers plant-1 and seed index. Similarly, the mean squares for most the traits in F1 hybrids were also significantly different (P ≤ 0.05). The analysis of variance for all the genotypes showed higher genetic variability among the genotypes which can further be exploited for various breeding programs to improve bread genotypes. Considering the F2 hybrids, the progenies Benazir x Sarang and Benazir x Anmol-92 gave desirable results for yield and its associated traits, indicating that above mentioned genotypes may be proved reliable genetic resources. With regards to heritability percentage in broad sense, the F2 progeny, Benazir x Sarang articulated high heritability for almost all studied traits, with the exception of grain yield plant-1 . The present findings suggested that most of the yield associated traits have been successfully transmitted. The information generated will be helpful for better understanding and selection of desirable material especially in advance generations.
