Abstract
The present investigation was conducted to examine the extent of phenotypic and genotypic correlation in bi-parental mating
and selfing for yield and related components. Sixty plants from every cross of barley (IBON-W-61 x DWR91, BH935 x
BH902 and BH902/DWRUB64) were randomly selected and crossed as well as selfed to generate 30 BIPs and 30 selfed
progenies in 2012-13. In 2013-14 those slefed and intermated progenies were grown in a compact family block design with
three replications. Data were recorded on days to heading, days to maturity, plant height, spike length, grain/spike, effective
tiller number per plant, biomass yield per plant, grain yield per plant, harvest index and 1000-grain weight. The genotypic
and phenotypic correlation coefficients were calculated between pair of characters. From the study it was concluded that
intermating has improved mean performance and variance of characters by breaking linkages between genes and resulted
in breakage of coupling phase and repulsion phase linkages that led to decreased and increased correlations, respectively.
