Twenty four genotypes comprising of 16 Avena spp. were studied for yield, quality characters and disease reaction at CCS HAU, Hisar during rabi 2010-11. The GCV, PCV, heritability, GA were highest for green fodder yield, followed by dry fodder yield, seed yield per plant and reducing sugar. A. sativa cv. OS 6 had maximum CP (14.54%) for grain while, A. barbata cv. HFO 58 had minimum CP value (11.97%). In case of IVDMD, A. brevis cv. HFO 864 (41.64 %) had minimum digestibility, whereas A. nuda cv. HFO 305 (64.28%) had maximum value. A. maroccana cv. HFO 867 had highest CP (14.51%) for fodder while A. barbata cv. HFO 58 had lowest CP (12.65 %). A. sativa cv. OS 376 had highest TSS (7.96 %) as well as reducing sugar (4.49 %) and A. nuda cv. HFO 305 had highest fat (9.45 %). All the genotypes were found moderately to highly resistant to diseases under study. The desirable genotypes of various Avena species either could be used as such or in hybridization programme to transfer the desirable characters to cultivated species.
