Exploring the genetic variability in F2 intraspecific crosses of bread wheat
Abstract
The wheat breeders are being focused to improve the yield potential of bread wheat by evolving new varieties with desirable genetic makeup in order to overcome the consumption pressure of ever increasing human population. For resolving this situation, a research was carried out on ten F2 populations along with their five parents grown in the Experimental Field, Botanical Garden, Department of Plant Breeding and Genetics, Sindh Agriculture University, Tandojam during the growing season of 2017-18. The experiment was carried-out in a randomized complete block design with four replications. The analysis of variance revealed significant differences among genotypes, parents and F2 crosses for all the traits studied. Such results signify the worth of breeding materials for further exploitation. Based on average performance, the parent AS-2002 and F2 cross Sehar-2006 × Kiran-95 showed promising performance for majority of studied traits including grain yield plant-1, showing their importance for future breeding programs. The genetic parameters indicated that from ten F2 progenies, Benazir × Sehar-2006displayed higher heritability estimates coupled with more genetic gain for maximum number of traits, showing a good parental combination for effective selection to improve wheat productivity in subsequent segregating generations.
