Abstract
Estimates of heritability (narrow sense) and genetic advance for nine characters including seed yield have been reported by studying F2, BC1 and BC2 generations in eight crosses of Linum usitatissimum L. High estimates of heritability were recorded for all the traits in cross combinations of T. 477 × IPI 6 and Afg. 8 × Neelam. Population of T. 397 × Mukta and EC. 22609 × No. 55 expressed high estimates of heritability for all the characters except for primary branches, secondary branches (low heritability) and capsule per plant (moderate heritability). Cross NP (RR) 9 × NP (RR412 and GLC. 2 - 1 × GLC. 6 showed low heritability only for 1,000 seed weight and moderate heritability for yield. Low heritability for primary branches, secondary branches and moderate heritability for seeds per capsule was exhibited in EC.22609 × No. 55, EC. 22585 × R. 17, EC9832 × Hira. The population of GLC. 1 - 1 × GLC. 6 showed lowest heritability for yield. Jn general, the estimates of genetic advance followed the estimates of heritability in all the crosses.
