Strawberry (Fragaria x ananassa Duch.) genotypes were evaluated to study variability, correlation and path analysis. Nineteen genotypes were planted using randomized complete block design with three replications during 2013-14. Fruit yield per plant had the highest PCV (56.25) and GCV (45.92). Highest heritability (H2, 73.10) was recorded for number of fruits per plant. Highest genetic advance (35.69) coupled with higher genetic gain (77.23 %) was estimated for fruit yield per plant. Fruit yield was significantly and positively associated with fruit length, fruit breadth, number of fruits per plant and average berry weight at both genotypic and phenotypic levels. Path coefficient analysis revealed that plant height had maximum positive direct effect (0.041) whereas average berry weight had maximum negative direct effect (-0.040) on fruit yield.
