Languages : English (eng) Keywords: Full season maize ; genotype grain yield Abstract: Nine Full season normal maize genotypes including Farmers' variety were tested in RARS,
Lumle during the year 2011-2012 for the varietal development of full season normal maize in
the western hills of Nepal. The genotypes were planted in RCBD with three replications.
Genotypes were tested considering different parameters; days to 50% tasseling, days to 50%
silking, plant height, ear height, grain yield. Data of different parameters were analyzed
separately and combined over years for all the treatments. Genotypes differed significantly for
days to 50% tasseling, days to 50% silking, plant height and ear height but were insignificant
for grain yield. Farmers' local was earlier for tasseling (73.8 DAS) and silking (77 DAS). It
was followed by genotype Rampur S03F08silking (74.7 DAS) and silking (77 .8 DAS).
Genotype BLSBRs07FI2 was with short plant height ((192.7 em) and ear placement height
(97.2 em). Genotypes Manakamana-3 (5.93 t/h) followed by Manakamana-5 (5.44 t/h) and
Rampur S03F08 (5 .1 tlh) produced higher grain yield. The genotypes were non-significant 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,
