Plant materials were utilized by L×T mating design of seven lines and three testers and their twenty one hybrids were sown in field during autumn season 2015 in RCBD design with three replications. Genetic variability, GCA and SCA among genotypes was assessed under the research area University of Agriculture, Faisalabad, Pakistan. The lines A-12, A-2.2 and tester G-53 were found good general combiners for days to flowering, plant height, number of leaves per plant, stem diameter, achene yield per head, 100 seed weight, oil content and protein content. Among the crossesA-12 × B-3.16and B-12.10 × C-3.3were performed as a good specific combiners for yield related traits. Especially for protein content the cross B-3.1 × B-3.16 showed the maximum SCA effects. Analysis of variance results were determined among entries for all the character at significant level (p ≥ 0.01-0.05). Keywords : Line × Tester, GCA, SCA, Protein contents and Yield.
