Characterization of finger millet (Eleusine coracana Gaertu.) Germplasm with agro Morphological makers / Bhattarai M
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 : Direct seeding : an emerging resouce conserving technology for rice cultivation in the rice-wheat system Material Type: printed text Authors: J. Tripathi ; Bhatta, M.R., Author ; S Justise, Author ; N.K Shakya, Author Pagination: 273-283 p. Languages : English (eng) Abstract: (DSR) has emerged as a viable alternative to transplanting (l'P R). Direct seeding with
different RCTs equipments such as power tiller drill (PTD) and zero till drill (ZTD) improved
the yield potential of DSR coupled with additional advantages of reduced or zero till system
for improved productivity, profitability and sustainability of the rice-wheat system.
Several experiments were conducted during 2002103 and 2003104 in the farmer fields of
Rupandehi districts following the participatory approach to evaluate the performance of
different DSR over conventional TP R. An experiment conducted in different farmers 'field in
2002103 revealed that PTD-DSR produced significantly higher yield over HBD-DSR (hand
broadcasted dry DSR) and marginally higher than the conventional TPR and HBW-DSR
(hand broadcasted wet.DSR). A couple of DSR experiments were conducted in the last rice
season (2003/04) on RCTs along with other methods of DSR and TP R. In one experiment
PTD-DSR was compared with Wet-DSR and conventional TPR and in other one ZTD-DSR
was eva.7;'.Qted with TPR including two rice varieties (Radha-4 and Sabitri). In first
experiment, PTD-DSR was found significantly superior to TP R and marginally superior to
HBW-DSR. In second experiment, ZTD-DSR proved significant superiority over TPR with
both of the varieties. However, Radh-4 produced comparatively higher yield than Sabitri in
both ZTD-DSR and TPR. Partial budgeting based on farmers interview and crop cut
sampling of above practices revealed that PTD-DSR, ZTD-DSR and HBW-DSR provided
33%, 22% and 21% higher net return respectively as compared to conventional TPR. The
higher economic return from all three direct seeding methods attributed to saving in total
variable costs and higher yield. Direct seeding with RCT equipments proved beneficial as
compared to conventional TPR qnd HBD-DSR. Broadcasted wet DSR (HBW-DSR) could
also be a viable option in the case where, RCT equipments are not available.Link for e-copy: http://elibrary.narc.gov.np/?r=1112 Direct seeding : an emerging resouce conserving technology for rice cultivation in the rice-wheat system [printed text] / J.

Title : Genetic Diversity in Nepalese Wheat Cultivars Based on Agro-Morphological Traits and Coefficients of Parentage Material Type: printed text Authors: Joshi, Bal K., Author ; Ashok Mudwari, Author ; Bhatta, M.R., Author Publication Date: 2004 Article on page: 7-17 p Languages : English (eng) Keywords: Agromorphological traits, coefficient of parentage, genetic diversity, Nepalese wheat cultivars Abstract: Genetic diversity between parents is necessary to derive transgenic segregants from a cross.
Coefficient of parentage (COP) and agromorphological traits (AMT) can be used to estimate
diversity among cultivars. The pedigrees of 26 bread wheat cultivars were traced back to 77
ancestors and computed coefficient of parentage for all pair-wise combinations. All the cultivars
used in the pedigree analysis were evaluated for six agromorphological traits in the National
Wheat Research Programme (NWRP), Bhairahawa, Nepal in 1996. Six quantitative variables were
used to compute dissimilarity distance matrix. Cluster and principal components analyses were
performed on the matrix of COP and AMT values. COP matrix and the matrix based on
agromorphological traits were compared. Mexico, India and Nepal were countries of the origin for
26 cultivars. A total of 77 ancestors originated from 22 different countries were used to develop
these cultivars. Most of the ancestors were aestivum (80.52%) and spring growth habit (64.94%).
Maximum dissimilarity was between RR 21 and Annapurna 3 and the most closely related pair
was Rohini and BL 1022 based on the AMT. The mean of COP for all cultivars was 0.159
0.256. The highest COP was between Annapurna 3 and Annapurna 2. Other more closely related
pairs based on COP were Kalyansona and Annapurna 2, Pasang Lhamu and Annapurna 3, UP 262
and RR 21, Vaskar and Kalyansona, NL 297 and BL 1473, Pasang Lhamu and Annapurna 1.
Completely unrelated pairs were L 52 and HD 1982, L 52 and Kalyansona, LR 64 and
Kalyansona, Kalyansona and HD 1982, PI and Kalyansona, PI and L 52, RR 21 and HD 1982, RR
21 and Kalyansona, RR 21 and PI. Fifteen ancestors were present in at least about 65% of the
cultivars. 17 ancestors had been used more frequently. Five and six clusters were formed based on
AMT and COP, respectively. Correlation coefficient between COP and AMT was 0.18 (P =
0.0168). Cultivars surveyed represent a wide range of variation for different areas of origin and
adaptation. This genetic variation may be useful for further improvement of wheat and it is
necessary to conserve them.Link for e-copy: http://elibrary.narc.gov.np/?r=72
