Title : A disease survey report on fingermillet in eastern and western hills of Nepal. Material Type: printed text Authors: Prasad, R.C. ; Khanal B, Author Publication Date: 2005 Pagination: 30-31 p. Languages : English (eng) Keywords: Survey, diseases, fingermillet, pyricularia grasea, blast Abstract: A survey programme was conducted on fingermillet in 2004 to hilly regions of the eastern and . western part of the country to know the situation of millet diseases and to study about them. Some millet growing of Dolakha, Sidhupalchowk, Syanja, Tanahu, Kaski & Nuwakot district were visited and appearance diseases were recorded at randomly selecting Ten plants in each field. Blast (Pyricularia grisea), Cercospora Leaf spot (Cercospora eleusine) and Helminthosporium leaf spot (Helminthosporium spp.) were observed among them Cercospora leaf spot disease was found only at higher altitude. Low severities of major diseases (Blast and CLS) were observed in all districts. Finger blast was observed ·up to resistant reaction in all the surveyed districts. The agronomically superior cultivars should be selected to maintain the genetic purity and seed multiplication programme for next season to distribute the farmers of that area.

Title : Effect of Promising Rice Genotypes on Leaf Blast Disease Progression Material Type: printed text Authors: B. Chaudhary, Author Publication Date: 1997 Article on page: 27-31 p. Languages : English (eng) Keywords: Blast, Pyricularia grisea, partial resistance, rate reducing, slow blasting. Abstract: Nine promising rice genotypes in 1993 and six in 1994 were evaluated for resistance to blast disease (Pyricularia grisea) at the Agriculture Research Station, Rampur, Chitwan. Of the genotypes, three were found promising with respect to leaf blast resistance in both years. Others had faster disease development and had higher terminal disease severities. Among the genotypes tested, AS 781-1 and NR 601-18-1-2, which were promising also in grain yield point of view, showed significantly slower disease progress and lower terminal disease severities. Thus, the genotypes need to be promoted for cultivation under disease prone areas in the country.

Title : Evaluation of rice genotypes against blast disease under field condition Material Type: printed text Authors: Nabin Kumar Dangal ; Bedanand Chaudhary, Author ; Parbati Joshi, Author ; Ang Tenjing Sherpa, Author Pagination: 323-330 p. Languages : English (eng) Keywords: Pyricularia grise a, genotype, disease severity, leaf blast and resist~ce Abstract: Blast of rice, caused by Pyricularia grisea, is one of the most important diseases of rice in
Nepal. It has been causing significant yield loss in all rice growing areas. A field screening
experiment was conducted to identify resistance in rice to the disease during 2011 and 2012
wet season at Regional Agricultural Research Station, Tarahara. A total of 134 (OBN -70,
RA VTRL-26, RA VTN-22 and Quality-16) rice genotypes were evaluated for resistance in
both the years. atural spread of the pathogen in the test lines was allowed from border lines I
inoculums rows planted around the nursery with mixture of susceptible varieties (i.e. Mansuli
and Sankharika). Conducive environment for blast development was created by planting four
rows of Sesbania eculeata around the experimental plot 35 days prior to seeding of test
genotypes. Scoring was done on 22 days after seeding and continued for three scorings at 7
days interval using 0-9 scale developed by IRRI. Area under disease progress curve (AUDPC)
varied significantly among the tested rice genotypes in both years. Disease severity varied 0 to
77.77%. Out of 134 entries, 58 entries were resistant to the disease during 2011 and 63 in
2012. Among them, IR09Fl12, IR09Fl20, IR09Fl27, IR09F158, IR09Fl66, IR09Fl74,

blast in both the years. The number of moderately resistant (3 -4), moderately susceptible (5 -6)
and highly susceptible (7-9) genotypes was 43, 9 and 2 in 2011 and 54, 3 and 1 in 2012,
respectively. Disease severity increased in second and third scorings in all entries except the
resistant ones. IR09Fll0, NR 1887-8-1-1-2 and Kanchhi masuli were highly susceptible to
blast with the highest disease score (7) which were completely knocked down in the final
scoring.Link for e-copy: http://elibrary.narc.gov.np/?r=919 Evaluation of rice genotypes against blast disease under field condition [printed text] / Nabin Kumar Dangal ; Bedanand Chaudhary, Author ; Parbati Joshi, Author ; Ang Tenjing Sherpa, Author . - [s.d.] . - 323-330 p.
