| Abstract: |
This study consisted of field survey, yield loss assessment and disease screening nursery
undertaken at RARS, Parwanipur and its command area during 2001102 and 2002103 with a ·
view to know the status of sheath blight disease of rice in Central Terai of Nepal and plan
future research programs accordingly. Survey in few command districts revealed sheath
blight prevalence in 75. 7% surveyed fields. Farmers reported almost 28% yield loss due to
this disease in susceptible farmer adopted rice variety "Sona Masuli" However, yield loss
assessment at the research station showed 9. 44% yield loss in this particular variety. Yield
losses varied between 4. 77 to 9.44% in different varieties. However, yield differences
between sprayed and non- sprayed plots were non significant. Relative lesion height was
significantly different among the tested genotypes and between the spray treatments as well.
Sheath Blight Screening Nursery conducted during 2001102 and 2002103 indicated NR 1769- -
20-2-2-3-4 as resistant genotype to rice sheath blight. Genotypes/varieties like Pusa 834, NR
1558-76-1-1-2-3-1-2-3, FRX 29F3B-5F6BF7, FRX 29F5B-5F6BF8, Sabitri, Radha-11,
Jaya, NR 1743-1-2-4-1-2-2, BR 802-78-2-1, NR 1736-4-6-2-1-1-1 were found moderately
resistant over years. |
