Title : Agro-morphological characterization of promising rice (Oryza Sativa L.) Genotypes for hills of Nepal Material Type: printed text Authors: R.K Basnet, Editor ; Bajracharya, J., Editor ; Upreti, H.K., Author Publisher: Hardinath, Janakpur : National Rice Research Programme Publication Date: 2010 Pagination: 93-101 p. Keywords: Rice ; quantitative and qualitative traits genetic purity promising genotypes agro-morphological characterization Abstract: A study on agro-morphological characterization was carried out to identify the key traits distinguishing the promising genotypes
developed by Agriculture Botany Division and to maintain the quality of seed with high genetic purity in laboratory and field in
2005 and 2006 rice season in Khumaltar. Four promising rice genotypes for mid- and high-hill conditions were agromorphologically
characterized along with two local varieties: Patle and Gudgud, and two standard checks of modern varieties:
Khumal-4 and Khumal-11. Altogether 14 different quantitative and 20 qualitative characters were observed at respective growth
stages of the rice plant following the ISTA Rules (2003) and standard rice descriptors (IRRI, 1980). A significant variability was
found for most quantitative traits (1.0 to 58.9% of CV) with two common .traits: two-clefted ligule and droopy panicle axis across the
genotypes under study. Variability was also observed in flag leaf angle with horizontal type in NR10492-7-22, Patle, erect in
NR10491-57-2-l, Khumal-11 and NR10515-69-1, and intermediate in rest of the genotypes; culm angle with intermediate and/or
erect type in most the genotypes and open in Patle. Likewise, strong to intermediate culm strength was found in six genotypes and
weak in Khumal-4 and Patle. Intermediate type of panicle was found in only two locallandraces with high sterility in Gudgud and
partial sterility in Patlc:: Thus, these promising genotypes were different from each other and can be easily identified based on these
qualitative and quantitative traits.Link for e-copy: http://elibrary.narc.gov.np/?r=1006 Agro-morphological characterization of promising rice (Oryza Sativa L.)

Title : Enhancing yield potential of rainfed rice using participatory plant breeding and participatory varietal selection during 2004/05 Material Type: printed text Authors: Yadaw, R.B., Editor ; Khatiwada, S.P., Editor ; B.

Abstract: Particip~tory pl~t breeding pro~m was initiated through in-situ project since 1999 with aim to address these problems by
developmg new nee genotypes. Smce last 7 years , 15 of F4 and 6 of F7 segregating population were grown at different fanners'
field of . .Kachorwa, Pakadiya and Lauki of Bara, Dhanusha, and Sunsari districs respectively. Three F4 and one F7 segregating
populations of.Kachorwa dhan -4 were grown at each farmer's field to select individual superior hills separately suitable in rainfed
with the active participation of plant breeder and farmers using bulk. method. Five out of 15 (F4) were selected and advanced to
subsequent generation till fixed.Among the distributed population, Kachorwa dhan-4,8,5,11( DudhisaroX BG-1442),25 LajhiX
Rampurmasuli),26 mansarax ,and 27 were found superior with their yield attributing characters. Where as, 4 out of 6 (F7)
Populations were selected for replicated mother trail. In (Participatory Variety Selection) PVS, 5 advanced lines including check of
5 sets were planted in farmers' field of Pakadiya of Dhanusha District and Lauki of Sunasari District Among the tested genotypes;
BR4684, IR58115, and IR67015 performed better in respect of grain yield and quality. Majority of the farmers preferred these
genotypes due to higher grain yield and their high milling recovery.Link for e-copy: http://elibrary.narc.gov.np/?r=1000 Enhancing yield potential of rainfed rice using participatory plant breeding and participatory varietal selection during 2004/05 [printed text] / Yadaw, R.B., Editor ; Khatiwada, S.P., Editor ; B.

Title : Floral trait variation in Nepalese wild and cultivated rice Material Type: printed text Authors: Resham B Amgai, Editor Publisher: Hardinath, Janakpur : National Rice Research Programme Publication Date: 2010 Pagination: 132-141 p. Abstract: Floral traits influence rice diversity, plasticity as well as its evolution and gene flow. Floral trait variation in Nepalese rice was
observed during 2006 at RARS-Lumle. They were evaluated at green house condition. 6 improved rice varieties and 31 rice
landraces were collected from terai and hill regions of Nepal. Similarly, 12 rice accessions (including male sterile) were collected
from IRRI and RARS-Lumle. 01yza rufipogon. 0. officinalis and 0. nivara (two accessions) were also observed during this study.
Higher variability was observed for glume opening angle, glume opening duration, stigma exertion, flag leaf angle, flag leaf
character, flag leaf length-breadth ratio, plant height, panicle length, panicle type, panicle exertion, spikelet fertility, pollen fertility,
stigma surface, style length, filament length, anther size and pollen diameter. 0. rufipogon was distinct with other rice while 0 .
nivara was found similar in many characters with landraces. The upland rice landraces Linde and Thulo Begani falls in same group
with cold tolerant rice Macchapuchre-3 and Chandannath-3 respectively. Glume opening angle showed good correlation with panicle
length {r-0.496, p<O.OOO), stigma exertion {r-0.472, p<O.OO I), stigma surface (r-0.386, p<0.007), filament length {r-0.3 18,
p<0.028) and anther size {r-0.508, p<O.OOO).Link for e-copy: http://elibrary.narc.gov.np/?r=1011 Floral trait variation in Nepalese wild and cultivated rice [printed text] / Resham B Amgai, Editor . - Hardinath, Janakpur : National Rice Research Programme, 2010 . - 132-141 p.

Title : Genetic relationship among Nepalese rice landraces and cultivars based on rapd markers Material Type: printed text Authors: Bimb, Hari P., Editor ; Joshi, Bal K., Author ; David Kansakar, Author ; Ekta Ghimire, Author Publisher: Hardinath, Janakpur : National Rice Research Programme Publication Date: 2010 Pagination: 168-184 p. Keywords: Genetic Distance ; rice RAPD Abstract: Genetic information of any genotype is necessary to manage and utilize them in conservation and breeding program. A total of 28
RAPD markers were used to relate the genetic structure among 50 Nepalese rice genotypes consisting of29landraces, 12 breeding
lines and 9 released cultivars. Some of them are aromatic and blast resistance. Only four primers (P41, P60, Pl09 and Pl41)
amplified the DNA of these genotypes with scorable bands. Primer 60 produced the highest number of bands (8). The highest
number of present bands (6) was shown by primer 41 in I 0 rice genotypes. Grouping of these genotypes based on the adaptation to
agro-climatic zone was not observed, probably due to low percentage coverage of genome by four primers. Most of the genotypes
grouped in two clusters. Kali Marsi and IR 24 formed separate individual cluster. Mansara and Jameli were the most similar
landraces (0.96). Churenodhan and Pranpyuri were the most closely related with Masuli. Only one genotype NR285-18 has fallen in
the first quadrant by principal component analysis and the fourth quadrant was empty. The highest contribution in PCl was from the
second band of primer 41 . This RAPD information can be used for selecting lines and for blast resistance breeding.Link for e-copy: http://elibrary.narc.gov.np/?r=1015 Genetic relationship among Nepalese rice landraces and cultivars based on rapd markers [printed text] / Bimb, Hari P., Editor ; Joshi, Bal K., Author ; David Kansakar, Author ; Ekta Ghimire, Author . - Hardinath, Janakpur : National Rice Research Programme, 2010 . - 168-184 p.
