| dc.description | Wheat (Tritium aestivum L.) is second after rice as a source of calories in the diets of
consumers in developing countries and is first as a source of protein (Braun ef al., 2010).
Wheat is an especially critical “staff of life” for the approximately 1.2 billion “wheatdependent” to 2.5 billion “wheat-consuming” poor-men, women and children-who live on
less than $US 2/day (FAOSTAT, 2010). The International Food Policy Research Institute
(IFPRI) projections indicate that the world demand for wheat will rise from 552 million
tons in 1993 to 775 million tons by 2020, and 60% in total by 2050 (Rosegrant et al.,
1997; Rosegrant and Agcaoili, 2010) | en_US |
| dc.description.abstract | Wheat (Triticum aestivum L.) is very important cereal crop in Bangladesh like developing
country. Bangladesh is bordered by Bay of Bangle and those areas are contaminated by
salinity and its cropping intensity is very poor. By utilizing those saline fallow lands for
wheat production it is possible to increase tonnage of total consuming food. But it is the
matter of consideration that yield is a polygenic character and very difficult for direct
selection for it. That is why it necessary to identify both of direct and indirect yield
contributing traits of wheat under saline condition. Ten wheat genotypes including
released variety and advance lines were evaluated for different yield related traits under
artificially created saline condition at HSTU, Dinajpur. The treated salinity dose was
fixed to 10 dS/m. This experiment was conducted at pot condition. The main aim of the
study was to understand the direct and indirect yield contributing traits in wheat and its
influences on yield under saline condition. Inter-relationship among yield and different
yield related traits were investigated by correlation and path coefficient analysis through
sowing wheat varieties/lines under salinity stress conditions. Major yield contributing
characters were taken in consideration. Present analysis revealed that spikelets per spike,
grains per spike, root length and root volume were the most important traits and showed
significant and positive relationship with yield per plant and the values are 0.394, 0.687,
0.737 and 0.797 respectively. Whereas heading day (-0.003), plant height (-0.714),
maturity day (-0.171), root weight (-0.112) and dry root weight (-0.112) showed negative
correlation at both genotypic and phenotypic level. The path analysis of genotypic and
phenotypic level showed that grains per spike, root length and root volume were
important direct contribution towards the yield per plant. Therefore grains per spike, root
length and root volume had maximum contribution for determining yield per plant in
wheat under saline condition. | en_US |
