Title : Varietal development research works for spring season rice under irrigated condition during Material Type: printed text Authors: Yadaw, R.B., Editor ; Khatiwada, S.P., Editor ; YP Yadav, Author ; Mahendra Tripathi, Author ; B. Chaudhary, Author ; HK Prasai, Author Publisher: Hardinath, Janakpur : National Rice Research Programme Publication Date: 2010 Pagination: 27-37 p. Abstract: Spring season rice is one option for increasing the yield under irrigated condition. This yield advantage can contribute considerably
to food security and alleviate poverty in the country. Therefore, varietal improvement works in spring season rice were performed
with aim to identify superior high yielding genotypes suited for double rice patterns. The tested genotypes; WAT-311 (4681kglha),
ZHEF-4 (4230 kg/ha), lET 3137 (4012 kglha), and IDSA-13 (4575 kglha) were found promising in respect of grain yield as well as
earliness in NRSON during 2004/05. During 2005/06, genotypes; OM1271 (5108 kg/ha), WAT 316 (5050 kglha), Judi 503 (50QO
kglha), Judi 141F (4891 Kglha), Judi 541 (4673 kg/ha) and ZHEF-4 (4239 kglha) produced higher grain yield with earliness in
NRSON. All the tested entries in lET, CVT and CFFT had highly significant differences in days to heading, days to maturity, tillers
1m2, plant height, panicle length, filled grains/panicle, unfilled grains/panicle, 1000 grain weight and grain yield at across the
locations during 2004/05-2005/06. Among the tested genotypes; WAT-307 (5125 kg/ha), WAT-316 (3737 kglha), IR 704213-

Keywords: Fine rice ; genotypes selection mid hills livelihood Abstract: Field experiments were conducted at Khumaltar farm involving 85 rice genotypes during 2004 and 101 in 2005 from previous
selection and exotic rice germplasm to identify input efficient, high yielding, and disease resistant superior rice genotypes for mid
hills. Multi location test of coordinated varietal and farmers field trials were conducted at Pakhribas, Lumle, Dolakha and
Dailekh.These lines were compared with standard check varieties in randomized complete block design. Five promising lines were
evaluated in the farmer's field for adaptability and acceptance test. Selected lines were NR10353-8-2-l, NR10414-34-2-3, NR10492-
7-2-2, NR10491-57-2-1, and NR10515-69-1 based on agro-morphological traits and quality parameters. The major traits used for
selection are days to maturity, plant height, grain type and size and yield. These lines were similar to or superior to standard check
varieties in most of the quality and other yield attributing traits. Among them NR10353-8-2-l was preferred by farmers due to its
input efficient high yield with fine quality rice and lodging resistant and released for general cultivation in the name of Khumal-8.

Languages : English (eng) Keywords: Maize ; grain yield significant far western Nepal Abstract: Intermediate yield trial (IYT) and coordinated varietal trial (CVT) of maize (terai set) were
conducted at Regional Agricultural Research Station (RARS), Doti during summer season of
the year 2012 and 2013. Twenty one genotypes of maize were included in IYT whereas
fourteen genotypes were included in CVT for both years. The experiments were laid out in
randomized complete block design with three replications. Amongst the tested entries
included in IYT during 2012, Rampur S03F08 recorded the highest grain yield (3609 kg/ha)
followed by Across 9531 (RE) (3474 kg/ha) and RPOP-1 (3223 kglha). Statistically, the
difference in days to flowering, plant height, ear height and grain yield due to genotypes was
found significant at 5% level. Similarly, same genotypes were planted in the year 2013 . Out
of the tested genotypes, Phraphuttabat S003 1 recorded the highest grain yield (5389 kg/ha)
followed by CEL-OHGY A x CELOH (5351 kg/ha) & Rampur S03F02 (53 12 kg/ha).
Statistically, the difference in days to maturity, plant height, ear height and grain yie ld among
the tested genotypes were found significant. Combined analysis over year indicated that the
genotypes Rampur S03F08 (4251 kg/ha), Across 9531 (RE) (4219 kg/ha), RPOP-1 (4099
kg/ha) and BLSBS07 -F 12 ( 4087 kg/ha) were identified as promising genotypes of maize for
river basin agro-environment of far western hills. Similarly, coordinated varietal trial of
maize was also conducted at RARS, Doti during 2012 and 20 13 . Fourteen genotypes of
maize including standard and local checks were included in the experiment of both years. The
experiment was planted in RCBD and it was replicated three times. Out of the tested
genotypes, RPOP-2 produced the highest grain yield (2645 kglha) followed by RPOP-1 (2407
kg/ha) and RPOP-3 (2268 kg/ha) during 2012. Statistically, the difference in days to
flowering, plant height and ear height due to genotypes was fow1d significant at I% level
whereas the difference in grain yield due to genotypes was found non-significant. The same
genotypes were planted in the year 2013 also. Out of the tested entries, RPOP-3 recorded the
highest grain yield (4880 kglha) followed by RPOP-4 (4304 kg/ha) and RPOP-2 (3885 kg/ha).
Statistically, the differences in all the traits included in the experiment due to genotypes were

Keywords: Maize ; grain yield significant far western Nepal Abstract: Intermediate yield trial (IYT) and coordinated varietal trial (CVT) of maize (terai set) were
conducted at Regional Agricultural Research Station (RARS), Doti during summer season of
the year 2012 and 2013. Twenty one genotypes of maize were included in IYT whereas
fourteen genotypes were included in CVT for both years. The experiments were laid out in
randomized complete block design with three replications. Amongst the tested entries
included in IYT during 2012, Rampur S03F08 recorded the highest grain yield (3609 kg/ha)
followed by Across 9531 (RE) (3474 kg/ha) and RPOP-1 (3223 kglha). Statistically, the
difference in days to flowering, plant height, ear height and grain yield due to genotypes was
found significant at 5% level. Similarly, same genotypes were planted in the year 2013 . Out
of the tested genotypes, Phraphuttabat S003 1 recorded the highest grain yield (5389 kg/ha)
followed by CEL-OHGY A x CELOH (5351 kg/ha) & Rampur S03F02 (53 12 kg/ha).
Statistically, the difference in days to maturity, plant height, ear height and grain yie ld among
the tested genotypes were found significant. Combined analysis over year indicated that the
genotypes Rampur S03F08 (4251 kg/ha), Across 9531 (RE) (4219 kg/ha), RPOP-1 (4099
kg/ha) and BLSBS07 -F 12 ( 4087 kg/ha) were identified as promising genotypes of maize for
river basin agro-environment of far western hills. Similarly, coordinated varietal trial of
maize was also conducted at RARS, Doti during 2012 and 20 13 . Fourteen genotypes of
maize including standard and local checks were included in the experiment of both years. The
experiment was planted in RCBD and it was replicated three times. Out of the tested
genotypes, RPOP-2 produced the highest grain yield (2645 kglha) followed by RPOP-1 (2407
kg/ha) and RPOP-3 (2268 kg/ha) during 2012. Statistically, the difference in days to
flowering, plant height and ear height due to genotypes was fow1d significant at I% level
whereas the difference in grain yield due to genotypes was found non-significant. The same
genotypes were planted in the year 2013 also. Out of the tested entries, RPOP-3 recorded the
highest grain yield (4880 kglha) followed by RPOP-4 (4304 kg/ha) and RPOP-2 (3885 kg/ha).
Statistically, the differences in all the traits included in the experiment due to genotypes were
found significant at 1% level. Combined analysis over year identified RPOP-3 (3465 kg/ha),
RPOP-2 (3415 kg/ha) and RPOP-4 (3286 kglha) as the promising genotypes for river basin
agro-environment of far western hills. Statistically, effect of treatment, year and interaction
between treatment and year was found significant at 1%.Link for e-copy: http://elibrary.narc.gov.np/?r=887 E-copies
