Title : Evaluation of rice genotypes against bacterial leaf blight and blast Material Type: printed text Authors: Purushottam Jha ; Surya Narayan Sah, Author ; Ram Baran Yadaw, Author ; Ram Baran Yadav, Author ; Anand Mandal, Author ; Dev Kumar Saphi, Author Pagination: 281-291 p. Languages : English (eng) Keywords: BLB Resistant Moderately resistant ; Susceptible and highly susceptible Abstract: A total of 354 rice lines in 2009 and 261 lines in 20 I 0 with a diverse genetic background were
evaluated for resistance to bacterial leaf blight over locations. Disease severity ranged from 0
to 9 in both the years. Bacterial leaf blight reactions in different genotypes were differed in
locations. During 2009, 263 genotypes were scored resistant (R) and 90 genotypes moderately
resistant (MR) and one susceptible at Parwanipur. Similarly, 244 genotypes were scored
resistant, 129 moderately resistant, one lines highly susceptible at Hardinath. Likewise, 193
genotypes scored resistant, Ill moderately resistant 39 were susceptible at Bhairahawa.
During 2010,107 genotypes scored resistant, 122 moderately resistant (MR), 33 lines
moderately susceptible (MS) and 2 lines susceptible at Hardinath. Similarly, in 20 I 0, 159
lines scored resistant, 50 moderately resistant (MR) and 23 moderately susceptible at
Parwanipur. This showed that there was prevalence of variable pathotypes over locations and
thus, genotypes need to be tested over locations to identify donor parents and resistant
genotypes for recommendation. Similarly, A total of 242 rice lines in 2009 and 261 lines in
20 I 0 with a diverse genetic background were evaluated for resistance to blast disease over
locations. Disease severity ranged from 0 to 9 in both the years. Blast reactions in genotypes
were differed in all locations. During 2009, 242 genotypes were scored immune, 27 resistant
(R) and 28 genotypes moderately resistant (MR), at Parwanipur. Similarly, 2 genotypes were
scored as 2 immune, 217 resistant, 9 moderately resistant, 7 highly susceptible at Nawalpur.
Likewise, genotypes were found as 78 resistant, 97 moderately resistant, 36 susceptible at
Hardinath. During 20 I 0, genotypes were found as 33resistant, 151 moderately resistant, 56
lines moderately susceptible (MS) and 9 lines susceptible at Hardinath. Similarly in 20 I 0, 261
lines scored resistant, I moderately resistant and 2 highly susceptible at Parwanipur. This

Title : Evaluation of Common Nepalese Rice Cultivars Against Rice Root Knot Nematode Material Type: printed text Authors: Deepak Sharma Paudyal, Author ; Ramesh R. Pokharel, Author ; Sundar M. Shrestha, Author ; G.B. Khatri Chhetri, Author Publication Date: 2004 Article on page: 33-36 p Languages : English (eng) Keywords: Meloidogyne graminicola, Oryza sativa, resistant sources Abstract: Twelve commonly cultivated rice cultivars viz. Radha-7, Ghaiya-2, Rampur Masuli,
Bindeshwari, Makawanpur-1, Sabitri, Janaki, Chaite-2, Radha-9, Radha-4, Chaite-6 and Masuli were
tested against rice root knot nematode (Meloidogyne graminicola) in sick soil under greenhouse
condition. Resistance screening of the cultivars was done based on the
reproducibility of M. graminicola to IR-29 susceptible check and disease intensity grade was
classified on the basis of root knot index. All the cultivars were susceptible to M. graminicola
except Masuli and Chaite-6, which were moderately resistant. Ghaiya-2 and Janaki were even more
susceptible than IR-29 and these cultivars can be used as susceptible check instead of IR-
29. Since the common cultivars were susceptible to M. graminicola, it is necessary to screen more
rice cultivars to explore resistant sources against root knot nematode of rice.Link for e-copy: http://elibrary.narc.gov.np/?r=76

Title : Evaluation of mungbean (Vigna radiata L. Wilczek) genotypes for terai and inner terai under rice and maize based cropping system of Nepal Material Type: printed text Authors: Darai, R., Editor ; Neupane R.K., Author ; NP Khanal, Author ; B. N. Adhikari, Author ; Sah, R.P., Author Publication Date: 2010 Pagination: 313-324 p. Keywords: Mungbean, Nepal, MYMV , CLS resistant line cropping patterns Abstract: Breeding strategies were directed to develop high yielding, synchronous, better quality varieties with yellow mosaic virus (YMV),
cercospora leaf spot (CLS) resistant and having wider· adaptability in Nepal. Two varieties introduced from A VRDC have been
identified superior and recently released in the name of Pratikchya and Kalyan with the joint venture of NGLRP and FORWARD.
These lines are characterized as semi synchronous, resistant to YMV and CLS and adapted for the rice based and maize based
system. Recent research efforts are concentrated to introduction of germplasm from international organizations and evaluation and
selection of these materials under on station and on farm experiments. Participatory variety selection (PVS), mother and baby trials
were running to test and disseminate pipeline technologies under on farm situation The genotypes Bari mung (850 kglha), CN9-5
(815 kg/ha), VC1973A {Sc} (810 kg/ha) were found promising compared to check pusa baisakhi(362 kglha) in OBN, Likewise
VC6173 B -10(975kglha), VC6173B-11(925 kglha) and VC6173A(900 kg/ha) were selected from AVRDC lines in 2005/06 and
will be promoted in multi location evaluation. Similarly, the research results in CVT revealed that the genotypes VC 6370(30-65),
VC6141-90, VC6369 (53-79) and NM54 produced higher yields than the standard check Pusa Baisakhi and local check Saptari local
in both years. Right now participatory plant breeding is the spirit of the time to grasp the potential ·yield and wider adaptability in

Languages : English (eng) Keywords: Disease severity ; Xanthomonas oryzae pv. Genotype Resistant and Susceptible Abstract: Bacterial Leaf blight (BLB) of rice; caused by Xanthomonas oryzae pv. oryzae, is one of the
most important diseases of rice in the eastern terai ofNepal. A field screening experiment was
conducted to identify the resistance in rice to the disease during 2011 and 2012 wet season at
Regional Agricultural Research Station, Tarahara. A total of 134 (OBN-71 , RA VTRL-26,
RA VTN -21 , Quality-16) rice genotypes were evaluated for resistance in both the years. Each
entry was planted in 2 rows of 2m length. Susceptible variety of rice (purple) was planted at
an interval of every 10 entries. The pathogen was inoculated in all entries at 56 days after
transplanting using Kauffmans clipping method. The disease was scored at 21 days after
inoculation and continued for three scorings at 7 days interval using 0-9 scale. Severity of the
disease varied significantly among the tested rice genotypes in both years. Level of disease
severity was higher in most entries in 2012 than 2011 . Disease severity varied 11 to 100%.
None of the genotypes were free from the disease. Out of 134 genotypes, 34 genotypes were
moderately resistant to BLB disease during both the years which were IR09F 146, IR09F 166,

which increased to 55 in 2012. There were no highly susceptible genotypes during 2011 , but
