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 : Characterization of finger millet (Eleusine coracana Gaertu.) Germplasm with agro Morphological makers Material Type: printed text Authors: Bhattarai M, Editor ; Ghimire, K.H. ; B.K. Joshi, Author ; Bhatta, M.R., Author Pagination: 184-189 p. Keywords: Finger millet ; agro-morphological makers diversity traits Abstract: Finger millet [Eleusine coracana (L.) Gaertn.] is an important crop of the millets group
cultivated in terai and hills of Nepal. A total of 537 accessions of finger millet were
characterized during the years 2010 and 2012 at National Agriculture Genetic Resources
Centre (NAGRC), Khumaltar, Lalitpur, Nepal. Standard characterization descriptors were
used to record 12 quantitative and 7 qualitative characters. Different measures of variation
like mean, standard deviation, range, Shannon-Weaver diversity indices (H') were used for
the assessment of diversity between the accessions. Highest degree of diversity was
observed for number of leaves (0.906) followed by leaf sheath length (0.902), ear exertion
(0.901), blade length of flag leaf (0.893), leaf blade width (0.886), heading days (0.885),
plant height (0.879), leaf blade length (0.872), number of productive tillers (0.860), finger
length (0.841) and ear size (0.830). With the R2 value of 0.6, 14 clusters were observed
based on Euclidean's distance (quantitative traits) whereas with the R2 value of 0.8, 12
clusters were observed based on Gower's distance (quantitative and qualitative traits).
Three principle components explained 96.13% of the total variation in the collection. Ear
shape (0.99) is the most important variable in principle component 1.Characterization of finger millet (Eleusine coracana Gaertu.) Germplasm with agro Morphological makers [printed text] / Bhattarai M, Editor ; Ghimire, K.H. ; B.K. Joshi, Author ; Bhatta, M.R., Author . - [s.d.] . - 184-189 p.

Title : Evaluation of Lentil (Lens culinaris Medikus) Germplasms on the basis of Agro-morphological Traits Material Type: printed text Authors: Gupta, S.R., Author ; KC, H.B., Author Pagination: 37-46 p. Languages : English (eng) Keywords: Agro-morphological Trait, Genetic Resources, Principal Component Analysis Abstract: Lentil (Lens culinaris Medikus) is a leading food legume and exportable commodity in Nepal whose seed yield is low and unpredictable as it is grown under limited soil moisture conditions during the winter months. However, there may be a potential to increase its yields by utilizing germplasm that is adapted to rainfed conditions and residual soil moisture from the preceding crop. National Agriculture Genetic Resources Centre (NAGRC) has collected and conserved 489 accessions of lentil germplasm in the NAGRC gene bank at Khumaltar. Among them, a total of 209 accessions of lentil germplasm were evaluated on the basis of agro-morphological traits at Khumaltar during 2008/09 and 2009/10. Tenqualitative and six quantitative traits were recorded to evaluate the variability on the basis of agro-morphological traits. Principal component analysis accounted 92.0% of the total variance among the accessions. Variability range for number of flower per peduncle was 2-3, for plant height 14.6-31.2cm and for maturity 117-130 days. The evaluated germplasm shows high variability in agro-morphological traits, which are very important in crop improvement programme. Evaluation and utilization of such valuable genetic resources would provide crucial information for its improvement in future.
