Title : Evaluation of rice genotypes for resistance to blast disease Material Type: printed text Authors: B. Chaudhary ; M Yadav, Author ; Yadaw, R.B., Author ; Chaudhary, D.K., Author ; PCP Chaurasiya, Author ; Chaudhary, R.N., Author ; B.N Mahato, Author ; Sah, D.N., Author Pagination: 327-335 p. Languages : English (eng) Keywords: Blast fungus ; rice genotypes sources of resistance pathogen variability Abstract: exotic were evaluated for resistance to blast over four locations during 2002 and 2003,
respectively. Disease severity varied over locations and years. Within locations, genotypes
showed variation in disease severity. During 2002, 186 entries were resistant (R), 40
moderately resistant (MR.), 14 moderately susceptible {MS), 32 susceptible (S) to disease at
Hardinath. At Lumle, 69 entries scored R, 75 MR, 66 MS and 62 S to the disease. At Rampur,
174 entries rated R, 19 MR and 3 MS to the disease while 78 failed to germinate. At
Tarahara, 236 entries showed R, 6 MR and 30 entries did nopt germinate. During 2003, 148
entries showed R, 16 MR, 4 MS and 20 S to the disease at Hardinath. At Tarahara, all the
tested entries were resistant to disease, indicating escape from disease during the growing
season. At Khumaltar, 169 entries scored R, 59 MR, 29 MS and 8 S to disease. At Nawalpur,
217 entries rated R, 21 MR, 9 MS and 11 S to the disease. However, 39 and 123 lines were
resistant to the pathogen over locations during 2002 and 2003 tests, respectively. This
indicated that the genotypes varied for disease reaction over locations suggesting the
prevalence of variable virulence in the pathogen population. In neck blast screening, 11
genotypes out of 274 entries showed R to MR to the disease over Hardinath and Rampur
during 2002 test. In 2003, 132 genotypes were R to MR to the disease at Hardinath. Blast
nursery also included 166 entries received from International Rice Research Institute in
2002. Of them, 60 entries were found resistant to the disease over Hardinath and Rampur.Link for e-copy: http://elibrary.narc.gov.np/?r=1119 Evaluation of rice genotypes for resistance to blast disease [printed text] / B.

Title : Evaluation of groundnut genotypes for cercospora leaf spot and rust resistance Material Type: printed text Authors: Prasad, Ram Chandrika ; Arjun Sah, Author ; Sarala Joshi, Author ; Gopal Parajuli, Author ; Ram Devi Timila, Author Pagination: 292-297 p. Languages : English (eng) Keywords: Disease ; Pathogen Variety and yield Abstract: In order to identify the sources of resistance 111 and 124 groundnut genotypes received from
national as well as international institutions were eva luated in the experiment under field
condition during two consecutive season 2011 and 2012 in a rod-row design with a plot size
of 2 rows of 3m long with susceptib le check providing artificial in oculation at NORP
Nawalpur among them, even not a si ngle genotype showed resistant reaction to early leaf spot
(Cercospora arachidico!a) and late leaf spot (Cercospora personata)in both test years in the
crop however, ICGV-05200, ICGV-06188, ICGV-96318, ICGV-99219, ICGV-00401 &
ICGV -97047genotypes observed resistant to early leaf spot in both season while ICGV series
97325,95412, 97100, 99027,95416,98 184 & 91104 resistant to late leaf spot with superior

resistant to early leaf spot and late leaf spot in all test season therefore, they might be used in
hybridization program to develop new varieties of groundnut and some of them could be
recommended for the purpose of general cultivat ion. Rust disease caused by Puccinia
arachidis was not found problematic during the period.Link for e-copy: http://elibrary.narc.gov.np/?r=914 Evaluation of groundnut genotypes for cercospora leaf spot and rust resistance [printed text] / Prasad, Ram Chandrika ; Arjun Sah, Author ; Sarala Joshi, Author ; Gopal Parajuli, Author ; Ram Devi Timila, Author . - [s.d.] . - 292-297 p.
