AB  - The manifestation of heterosis has brought an economic revolution to the agricultural production and seed sector in the last few decades. The present research was examined to estimate the comparative performance of newly developed F. crosses of oat with commercially used modern oat cultivars in North-western Himalayan regions. Forty hybrids were developed using 10 female and 4 male parental lines of oat during<em> Rabi</em>, 2021-22. These crosses were evaluated in Randomized Complete Block design with three replications along with 3 checks during<em> Rabi</em> 2022-23 at CSK Himachal Pradesh Agricultural University, Palampur. Thirteen seed and fodder yield traits were analyzed for heterosis. The oat hybrids showed heterotic superiority up to -9.50% for earliness, 36.79% higher number of leaves, 67.51% higher number of tillers and 44.38% increment in plant height over the best commercial check. For green fodder yield and dry matter yield, heterosis was observed up to 117.78% and 141.94%, respectively. The magnitude of heterosis for seed yield per plant over the best check HJ—8 ranged from -26.68% to 44.49%. Conclusively, based upon earliness, high seed yield, plant height and fodder yield per plant, five cross combinations viz., PO-l XJHO-851, OS-6XHFO-114, PO-l XUPO-212, JHO-813XJHO-851 and OS—377XJHO-851 were adjudged to be the best.
