| dc.description | Rice is an ancient food grain. It has been used as food by man for over 10000
years and has fed a great number of people for a longer period than any other
crop. Rice is the staple food for more than halfofthe world population and grows
than 100 countries (FAO, 2000). China, India, Indonesia, Bangladesh,
Thailand, and Vietnam produce about 80 percent of the world rice production.
Among the leading rice growing countries ofthe world, Bangladesh ranked fourth
in both rice area and production (IRRI, 1995). But the position ofBangladesh is
critical due to its highest population density in a situation where majority of
rice growing areas are rain fed and flood prone. Rice accounts for 95 percent of
the food grain production in Bangladesh. Rice production in Bangladesh was less
than 10 million tons in 1970 and then exceeded 30 million tons in 2011
(BBS,2011 and DAE, 2011). Rice is one ofthe most important cereal crops in our
country. It is central to Bangladesh’s economy and agriculture. Rice accounted
for nearly 18% of the national GDP and provided about 70% of an average
citizen’s total calorie intake (BRRI, 2010). Rice area totaled about 10 million ha,
and accounted for 75% of the total cropped area and 93% of total area under
cereals (DAE, 2010 and BBS, 2010). | en_US |
| dc.description.abstract | A field experiment was conducted to assess the Biochemical and Physiological
characteristics to screen out the yielding potentiality and grain quality ofsome cultivars
( VI Bashful, V2 Posursail, V3 Gochi, V4 Taipi, V5 Paiza, V6 Lafaya, V7 Jirashail, V8
BRRJdhan 28 and V9 Banglamoti). Proline and chlorophyll were estimated from leaves
and protein, starch, moisture and some minerals like Fe, Zn, and Ca contents were
determined from the grains. Grain characters ie grain shape, size; length, breath and
length/breath were also measured for screening out the popular rice cultivar(s). Most of
the varieties showed low levels of low temperature tolerance during the growth stage,
the exceptions being some varieties of Poshurshail from Hobigonj, Pariza and Jirashail,
which were tolerant or moderately tolerant, to low temperature due to accumulate
higher amounts of proline. Lafaya and BRRIdhan 28 performed very poorly at low

synthesis in some rice cultivars was observed. Varieties from Hobigonj (Poshurshail)
and Joypurhat(Pariza) showed consistent tolerance to low temperature at all growth
stages. These varieties are potentially important gene donors for breeding and genetic
studies. So the breeders can consider these cultivars during their varietals improvement.
V2, V4 and V6 was found having lowest starch and VI, V5, V6 and V2 found higher
quantity of protein which is very important finding for selecting the variety for quality.
The study summarized that, not a single cultivars was found which containing all the
