Keywords: Maize  hybrids  ;  winter  season Abstract: National Maize Research Program (NMRP) has initiated research to identify suitable maize hybrids developed by multinational companies for general cultivation as short-tenn strategy using the fund of respective seed company in central and eastern Tarai since last three years. In the process of evaluation, NMRP has assessed 69 and 56 hybrids in 2011 and 2012, respectively from 12 multinational companies in collaboration with RARS, Parwanipur and RARS, Tarahara during winter cropping season along with two OPVs and one hybrid check. The experiment was carried out in randomized complete block design with two replications at both locations in Rice-Maize cropping system and three replications at Rampur in Maize-Maize cropping system. Plot size was four rows of 5 m lengths with 75 em x 25 em (RR x PP) spacing and 160:60:40 kg ha"1 NPK, respectively. Five hybrids from three multinational companies and 11 hybrids from six multinational companies were registered in 2010 and 2011, respectively based on the infonnation provided by the respective seed company. Sixteen hybrids from twelve multinational seed companies were registered in 2012 based on the results of collaborative experiments conducted by National Maize Research Program.

Maize varietal improvement for terai, inner terai and food hill valleys of Nepal / Kunwar, C.B.    

Public ISBD in Proceedings of the 27th National Summer Crops Workshop, held at Rampur, Chitawan, 18-20 April 2013, Vol. II / Giri, Y.P.     Title : Maize varietal improvement for terai, inner terai and food hill valleys of Nepal Material Type: printed text Authors: Kunwar, C.B., Editor ; B.N Chaudhari ; Sah, Y.P., Author ; Bhurer, K.P., Author ; Dhakal, J., Author ; J.B Chhetri Keywords: Open  Pollinated  Varietis  (OPVs)  Genotypes  ;  Coordinated  varietal  trial  Terai  inner  terai Abstract: With the objective of identifying high yielding, disease resistant yello'Y maize varieties, a series of experiments were conducted during 2010-2012 in RCB Des~gn. In the Intermediate Yield Trial-Terai Set (IYTT), twenty-one genotypes including standerd check were tested. The result obtained from the combined analysis at four locations (RARS Parwanipur, ARS Belachapi, ARS Surkhet, and NMRP Rampur) sh.owed that the genotypes R POP-1 found highest yielder (5.89 tlha) followed by R POP-2 (5.82 tlha) and RAMPUR S03F04 (5.78 tlha) were produced higher grain yield respectively. In the Co-ordinated Varietal Trial-Terai Set (CVTf), the trial was composed multi-location testing for six locations on winter season (NMRP Rampur, RARS Tarahara, RARS Parwanipur and ARS Belachapi) and OJi summer season (NMRP Rampur, ARS Surkhet and ARS Doti) with fourteen treatments including checks. The combined analysis revealed that the genotype Rampur population-2 produced the highest grain yield (5.88 t/ha) followed by Rampur Population-4 (5.67 tlha), ACROSS9331RE (5.49 tlha) and BLSBS07F10 (5.24 tlha) respectively. All the genotypes were found highly significant at 15% moisture level for grain yield.
