Estimation of genetic parameters, genetic, phenotypic and path coefficient analysis were conducted to evaluate forty eight genotypes of lentil introduced from International Center for Agricultural Research In the Dry Areas ICARDA, in addition the local variety Ebaa 98. The genotype seeds were planted at the Experimental Fields of Technical Agricultural College Mosul under to rainfall conditions in the spring season of 2011-2012. The following characters were studied: number of days 50% flowering , plant height , number of primary and secondary branches/plant, number of pods/plant , number of seeds/pod,1000- seed weight, biological yield , seed yield (kg/ha) and harvest index. The results showed that there were a significant genetic and phenotypic differences from zero for all traits. Genetic and phenotypic coefficients variances were high for 1000-seed weight, harvest index and number of pods/plant. Heritability values in broad sense were higher for plant height, number of seeds/ pod and seed yield. The values of expected genetic advance as a percentage were high for number of pods/plant, 1000-seed weight, seed yield and harvest index. The indirect effects values for phenotypic path coefficient on seed yield were positive and low for number of pods in plant, number of seeds/pod and number of primary branches
