The present investigation entitled “To the estimate heterosis for yield and yield components in linseed (Linum usitatissimum L.) germplasm” was undertaken to collect information on genetic parameters for yield and its components from a ten parents diallel mating design in linseed at Crop Research Centre (Chirodi), Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut (U.P.) during rabi 2013-14 and 2014-15. The experimental material was comprised of 10 diverse parents and their 45 F1s excluding reciprocals of a diallel cross. All genotypes were evaluated in a Complete Randomized Block Design with three replications. The data were recorded on twelve characters; days to 50% flowering, days to maturity, plant height, number of primary branches per plant, number of secondary branches per plant, number of capsules per plant, number of seeds per capsule, 1000 seed weight, biological yield per plant, harvest index, oil content and seed yield per plant. Thirteen cross combinations which showed the highest value of heterosis for seed yield, namely; Sweta × Garima, Sweta × Shekhar, Sweta × Kiran, Sweta × Surbhi, Sweta × Mukta, Garima × Shekhar, Garima × Shubhra, Garima × Kiran, Garima x T-397, Garima × Neelam, Garima × Mukta, Garima × Hira and Shubhra × Neelam over better parent may be exploited for developing hybrids with better yield in linseed.
