 ABSTRACT

A trial was conducted to  study selection parameters for grain yield and related characters in a diallel cross set  10  parents, 45 F1 S and 45 F2 S  barley were evaluated in randomized complete block design with three replications. Grain yield per plant  exhibited positive and highly significant correlation with  plant height, number of productive tillers per plant,  length of spike, 1000- grain weight,  biological yield per plant and harvest index. while it showed positive and non- significant correlation with days to maturity, Canopy temperature depression, leaf area index and number of grains per spike. The negative and non-significant correlation with   days to 50% flowering  and grain weight per  spike at phenotypic levels. Highest positive and substantial direct on grain yield per plant were exerted by biological yield per plant and harvest index at phenotypic level.  Low values of direct were recorded for remaining characters and indicated that direct contribution of these characters was low. The path coefficient analysis helps in partitioning of the total correlation into its direct and indirect components. The correlation coefficient measuring the degree of symmetrical association among two or more  variable, which helps in understand the nature and quantify of association between yield and its attributes the significance genotype correlation could not be tested as an any suitable statically test is not available, yet there magnitude is considered in relation to the corresponding phenotype estimates.

Key words: Barley, Correlation co-efficient, Path co-efficient, Grain yield per plant.
