ABSTRACT
Sixteen strawberry genotypes were evaluated to determine coefficients of variation, heritability, genetic gain and genetic advance and the nature of association among different yield contributing attributes and their direct and indirect contribution towards yield for the year 2011-12 and 2012-13. The genotypic and phenotypic coefficients of variability (48.41 and 48.55) , broad sense heritability (99.4 %) and genetic gain (99.3 %) was highest for total yield. Maximum positive significant genotypic and phenotypic correlation of yield was observed with fruit length (0.921 and 0.909), followed by fruit breadth (0.894 and 0.889 ), number of fruits per plant (0.889 and 0.877), berry weight (0.893 and 0.881). Path coefficient analysis revealed that no. of fruits per plant (0.542) had maximum positive direct effect on yield per plant followed by berry weight (0.435) and fruit breadth (0.435).These important traits may be considered in selection programme for the further improvement of yield in strawberry.
