Summary: NMRP hybrid trial and different CIMMYT hybrid trials were tested during summer season of 2000 at Rampur and Surkhet and winter season of 2000/01 at Rampur, Parwanipur and Hardinath. Two hybrid trials namely CAHTY01-2 (early) and CAHTY01-2 (late) were also tested at Rampur during summer season of 2001. The objective was to identify the superior hybrids or at least those equivalent to existing commercial hybrids. Analyses of NMRP hybrid trials revealed that the treatments were non-significant for grain yield at Rampur, but they were highly significant at Parwanipur. In Parwanipur, the hybrids RL14 X CML288 and CML 288 X RL1 were found promising. The result of T AMNET (early) at Parwanipur revealed that the hybrids CTS991058, CTS991050, CTS991062, CTS 991056 and CTS 991018 were superior to others. Similarly in TAMNET (late) tested at Rampur during winter 2000/01, the hybrids Him 129 produced highest grain yield (10.27t/ha) followed by NT 5188, NS X 202002, NS X 982009 and SW 3851. However CTS993048, CTS993004, CTS993064 and CTSO03056 were selected, as they were CIMMYT hybrid and better or equivalent to check variety also. The hybrids CAO0304 X CAOO328, CA00302 X CLO2836, CA00302 X CA00326, CA00310 X CAOO304 and CAO0302 X CL02846 were found promising from the result of CAHTYOO-2 during winter at Rampur. Combined analysis over location (Hardinath and Parwanipur) of CHTTYQ during winter revealed that the hybrids CMSQ983018, CMSQ993002, CMSQ983022, CL-G2501 X CLO2450 and CMSQ993008 were promising. The hybrids 983020, CMS983046, CMS983010, CMS983042, CMS983044 and CMS 983032 were found better for grain yield from the result of CHTTY at Parwanipur. During summer season of 2001, Tropical early Yellow DMR hybrid trial (CAHTYO1-2) was tested at Rampur and the hybrid CA1451 X CA14707 , CA14520 X Ca00106, CA14701 X CML421 and CA03116 X CAO0102 were found superior to others. Similarly late yellow DMR hybrid trial was tested in the same season at Rampur. The result showed that CAOO376 X NE4020, CAO0310 X CL02836, CAO0372 X CAO2803, CAOO370 X CA34502 and CAO0350 X CAOO302 were superior among the tested entries.
