Abstract: A study was made in linseed (Linum usitatissimum L.) to assess the extent of heterosis in 25 F₁ hybrids derived from line X tester fashion. The 25 F₁ hybrids and their ten parents (5 lines X 5 testers) were used to estimate the heterosis ten traits including seed yield. The derived twenty five crosses were studied to investigate heterosis over standard checks RLC-4 and NL-260. The best crosses based on heterosis and sca effect per se performance were OL-98-13-01 x LMS-210-01-27, RL292-02 x T-397, NL-97 x SHARDA, SLS-89 x SHARDA, and OL-98-03-01 x SHARDA, was identified as the best crosses combination. These better performing hybrids can be used for exploiting hybrid vigour.
