Title : Evaluation of CIMMYT hybrids and NMRP developed inbred lines Material Type: printed text Authors: Koirala, K.B., Editor ; Gurung D.B. ; Rijal, T.R., Author ; J.B Chhetri, Author ; Sah, Yamuna Prasad, Author ; Mitali Shah, Author ; Shrestha, J., Author Pagination: 155-162 p. Keywords: Inbred maize ; crossing selfing hybrid Abstract: Six sets of hybrid trials both yellow and white grain type received from CIMMYT during
2011 were evaluated under multilocations (Rampur, Parwanipur, Belachhapi and
Nepalgunj). The result from Tropical Low Land Hybrid Maize Trial (10ASA15HW10)
centaining eighteen genotypes and tested at Rampur revealed that SRR-C2SA6HS90-1-2-1-
B/CLA127, CLA135/CML399 and CML247/CML254/CLA135 were found significantly
high grain yielder. In CIMMYI' Hybrid trial (10BSA16HY) consisting of twenty
genotypes, hybrids namely (CML172 x CLQ6601)-B-B-8-B-1-1-B-B/CML161, V305-34-
3-2-B/CML165//CL02450, and (CLA37/CLA16)-B-B-B-4-B/CLA41//CL02450 performed
well?. Similarly, in CIMMYT Hybrid trial (TTWCWL24) consisted of twenty hybrids, the
promising genotypes were CLRCW96/CLRC, CL-RCW42/CML and CML49l/CLQRC for
grain yield and other quantitative traits. Likewise, CIMMYT Hybrid trial (TTWCWL25)
consisted of twenty genotypes was planted in Parwanipur and Nepalgunj. The superior
hybrids at Parwanipur for grain yield production were CLRCW96/CLRC, CML-
491/CLQRC and CLQ-RCWQ10/C, and at Nepalgunj CLRCW85/CLRC,
CML502/CLQRC and CL-RCW42/CML were found superior for grain yield. During 2011
winter season at Rampur 197 inbred lines were evaluated for per se performance and best
inbreds were RML-4, RML-5, RML-84, RML-95, RML-96, RL-14, RL-11 I, RL-105,
NML-2 and RML-19 which were used both for sel:fing and crossing with what?. Seed
increase of 239 fixed inbreds were carried out at Rampur applying control pollination.
Moreover, during 2012 winter season a total of 164 inbred lines were evaluated to see their
per se performance and other agronomic traits. Based on overall performance, RML-64,
RML-4, RML-90, RML-91, RML-103, RML-122, RML-127, RML-129, RML-134, RML-

Title : Evaluation of Maize under high temperature condition Material Type: printed text Authors: Gurung D.B., Editor ; K.P Dhital ; Shrestha, J., Author ; Bhurer, K.P., Author ; J.B Chhetri Pagination: 82-84 p. Keywords: Anthesis-silking interval ; grain yield high temperature maize Abstract: High temperature is an important constraint of yield reduction in maize. In order to identify
superior maize genotypes under high temperature, forty four genotypes were evaluated in
randomized complete block design with three replications at Parwanipur, Nepalgunj and
Rampur during summer season of 2010. The pooled analysis over locations showed that
TLBRS07F16 produced the highest grain yield with shorter ASI and bigger ear length
(2809 kglha, 3.3 days, 14.43 em) followed by RPOP-4 (2417 kglha, 1.8 days, 13.66 em),
TLBRS07F14 (2316 kglha, 3 days, 14.25 em), BLSBS07F10 (2159 kglha, 2.2 days, 14.42
em), Manakamana-3 (2108 kglha, 2 days, 14.75 em) and Upahar (2108 kglha, 3.5 days,
14.33 em). Therefore it was concluded that TLBRS07F16, RPOP-4, TLBRS07F14,
BLSBS07F10, Manakamana-3 and Upahar were best genotypes under high temperature

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
