| dc.description | Wheat (Triticum aestivum L.) is the worldwide popular cereal crop. It ranks
first in area (208765 thousand hectares) and production (556349 thousand
metric tons) among the grain crops in the world (FAO, 2003).
In Bangladesh wheat is the second most important staple food crop after
rice. In 2005-2006, cultivated area of wheat was 479,350 hectares with total
production of 735,000 metric tons (BBS, 2006). However, per hectare yield
of wheat in Bangladesh is low in comparison to other wheat growing
countries of the world. Even, the average wheat yield 2.68 t ha” in the world
in 2002 (FAO, 2003) was much higher than that of Bangladesh. There are
many factors behind the low yield of wheat in our country. Among these
factors late sowing, poor crop management and attack of various pest and
diseases play important role in reducing the yield of the wheat. | en_US |
| dc.description.abstract | A total of 89 wheat genotypes were screened against Bipolaris leaf blight
caused by Bipolaris sorokiniana under field condition. The experiment was
conducted at Wheat Research Center Nashipur, Dinajpur during 2007-2008
crop seasons. Disease severity was rated three times as percent leaf area
diseased (%LAD) on flag and flag-1 leaves of main tillers under three
different dates of sowing. Percent disease index (PDI) and area under
disease progress curve (AUDPC) were calculated using standard formulae.
The genotypes were graded for their reactions into different resistance
groups based on the final disease ratings on flag leaves averaged over three
dates of sowing. Result shows that out of 89 genotypes screened, 10 were
moderately resistant, 56 moderately susceptible and 23 susceptible. But
none of the genotypes were found highly resistant or highly susceptible. The
moderately resistant genotypes showed relatively lower PDI and AUDPC
values than those of the susceptible ones. Plant growth and yield varied
significantly among the different lines and varieties tested. | en_US |
