Title : Evaluation of rice genotypes for resistance to bacterial blight Material Type: printed text Authors: B. Chaudhary ; M Yadav, Author ; Yadaw, R.B., Author ; DB Gharti, Author ; Akhtar, T., Author ; Bhandari, D., Author Pagination: 344-348 p. Languages : English (eng) Keywords: Bacterial blight ; rice lines resistance locations pathotypes Abstract: A total of 244 rice lines in 2002 with a diverse genetic background and 248 in 2003 were
tested for resistance to bacterial blight (BB) over locations. Disease severity ranged from 0
to 9 in both the years. Genotypes differed in disease reaction to BB over locations. During
2002, 4 genotypes scored resistant (R), 104 moderately resistant (MR), 101 moderately
susceptible (MS), 46 susceptible (S) and 19 highly susceptible (HS) to BB at Hardinath. At
Parwanipur, 201 genotypes rated immune. 36 R, 25 MR. and 10 MS to BB. At Bhairahawa, 3
genotypes showed R, 146 MR. 75 MS. 37 Sand 13 HS to BB. During 2003, 3 genotypes
registered R. 112 lv!R. 82 MS, 42 Sand 23 HS to BB at Hardinath while 16 entries did not
germinate. At Parwanipur, 85 enrries were immune, 109 R, 53 MR and 17 MS to BB while 13
entries failed to germinate. At Bhairahawa, 3 entries recorded R, 51 MR. 62 MS, 65 Sand 97
HS to disease. However, 58 and 22 genotypes were R to MR over locations during 2002 and
2003 tests, respective~v. 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.
Out of 216 genotypes including standard and local r;hecks received from International Rice
Research Institute. 45 entries were R, 92 MR. 49 MS. 23 S and 4 HS to BB in 2003 test at
Hardinath, and the rest 3 entries did not germinate.Link for e-copy: http://elibrary.narc.gov.np/?r=1121 Evaluation of rice genotypes for resistance to bacterial blight [printed text] / B.

Title : Evaluation of rice genotypes for resistance to blast disease Material Type: printed text Authors: B.

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 rice genotypes for resistance to sheath blight disease Material Type: printed text Authors: B. Chaudhary ; M Yadav, Author ; Yadaw, R.B., Author ; Chaudhary, D.K., Author ; Akhtar, T., Author Pagination: 336-343 p. Languages : English (eng) Abstract: A rota/ of 90 rice genotypes in 2001 and 157 in 2002 of different genetic background were
evaluated for resistance to sheath blight caused by Rhizoctonia so/ani at National Rice
Research Program, Hardinath. In 2001, out of90 genotypes 5 were moderately resistant, 36
moderately susceptible and 49 susceptible. The disease severity was very high in 2002 in
comparison to that in 2001. Out of 157genotypes, 5 showed moderately susceptible, 101
susceptible and 51 highly susceptible. BR 268-4-6-1-4-3-3-5-2, NR 1743-1-2-4-2-2, NR

1-3-1 scored moderately resistant reaction to the disease in 2001. However, none of the
tested genotypes showed resistant to the disease in both years. This indicated that integrated
