An investigation was carried out on nine parents and their 36 F1’s obtained through a diallel crossing system to generate information regarding the relative heterosis, heterobeltiosis and standard heterosis. The population was laid out in CRBD with three replications, in kharif 2017 under Palampur (H.P.) conditions. Palampur-93 × KU-553, Palampur-93 × IC-413304, Palampur-93 × HPBU-124, Him Mash-1 × DKU-98, HPBU-111 × KU-553, DU-1 × IC-413304, DU-1 × IC-281994, DKU-98 × IC-413304 and DK-98 × IC-281994 surpassed the standard variety Palampur-93 for earliness by exhibiting high significant negative heterosis for days to flower initiation, days to 50 per cent flowering and days to 75 per cent maturity. HPBU-111 × KU-553 and DU-1 × IC-413304 had standard heterosis for maximum number of traits along with seed yield. HPBU-124 × KU-553, HPBU-124 × DU-1, HPBU-111 × IC-281994, DU-1 × KU-553, DU-1 × DKU-98, KU-553 × IC-413304 and DKU-98 × IC-281994 exhibited standard heterosis for more than three traits. High heterobeltiosis obtained for all the traits indicated the role of non-additive gene action in their inheritance.
