Exploitation of heterosis and gene action for yield of barley

The present investigation entitled ¿Exploitation of heterosis and gene action for yield of barley¿ was undertaken to: (1) to work out genetic variability, heritability and genetic advance in per cent of mean, (2) to estimate general and specific combining ability, variances and their effects, (3) to study nature and magnitude of gene action for yield traits and (4) to study the nature and extent of heterosis over better parents and standard variety for yield and their components. The present study was carried out during Rabi seasons of 2014-15 & 2015-2016 at Genetics and Plant Breeding Research Farm of Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad. The experimental materials comprised of nineteen genetically diverse varieties/strains and their 30 crosses. The 13 parents were involved in a crossing programme to develop a line × tester set (10 lines + 3 testers) during Rabi season of 2014-2015.
