Abstract	The present investigation was carried out at Banaras Hindu University to study heterosis and mixing abilities for yield-determining traits in barley. The differences among the parents were highly significant for all the traits. The mean squares due to lines and testers were highly significant for all the characters studied. The expression of heterosis varied with the crosses as well yield attributing traits, was appreciable in both nature and magnitude over standard check. For grain yield, the maximum per cent heterosis over standard check was observed in Lakhan×K-551, Lakhan×Geetanjali and Lakhan×Harmal while the crosses RD-2552×K-551 followed by Lakhan×K-551 and Lakhan×Geetanjali showed positive significant heterosis over better parent. For proline content, the top auspicious crosses exhibiting heterobeltiosis were, HUB-113×Harmal, HUB-113×Moroc-9-75 and HUB-113×K-551. High heterosis was also reported for days to 50% flowering, days to maturity, plant height, number of effective tillers and stomatal conductance. High positive and significant gca estimates for grain yield per plant were observed for K-551 followed by Harmal and Azad. Considering specific combining abilities, Lakhan×Geetanjali, Jyoti×Moroc-9-75, Lakhan×K-551, HUB-113×Moroc-9-75 and Jyoti×Azad were some of the engrossing crosses for grain yield per plant.
