Areas where maize is consumed as staple, consumers are suffering from vitamin A deficiency. To tackle this problem, pro-vitamin A maize genotypes both open-pollinated and hybrid types received from International Maize and Wheat Improvement Centre were evaluated at National Maize Research Program, Rampur; Horticulture Research Station, Dailekh; Agriculture Research Station, Surkhet and in farmers’ field at Sandhikharka in Arghakhanchi district during summer season of 2014/015. Experiments were consisted of 25 genotypes and planted in rendomized complrte block design with three replications. Poshilo Makai-1 and RML-86 x RML-96 were used as checks. Highly significant differences among the tested genotypes for grain yield were recorded. Likewise, highly significant differences between the locations and significant differences for location by genotypes for grain yield were observed. Results when combined over locations, genotypes namely normal hybrid RML-86 x RML-96 produced the highest grain yield (7030 kg ha-1) followed by pro-vitamin A genotypes CML451-B-B/CML323//(GEM-0043 x CML465)-1-1-3-B (6808 kg ha-1), CML451-B-B/CLHP0002-B//(Cel FSR/SPMAT/MBR 9958)-B-32-2-2-B-B (6382 kg ha-1), CML496-B/CLHP0003-B// (CML329/CML20)F2-3-4-B-B-B-B-B (6375 kg ha-1), CML486/CLHP0003-B// (CML329/ CML20)F2-3-4-B-B-B-B-B (6201 kg ha-1), CML551/CLHP0002-B//(P147-F2#152-S7/CML323)-F2-B-1-1-1 (6111 kg ha-1) and CLHP0003-B/CLHP0005-B//CLHP0352 (6095 kg ha-1). Days to flowering, and plant and ear heights of these selected genotypes were at par with previously released improved maize varieties and thus fit into farmers' existing cropping pattern.
