| dc.description.abstract | Five wheat genotypes (BARI Gom 26, SATYN 2, SATYN 11, SATYN 12, SATYN
31) grown under well water and water deficit stress condition at the research field of
Crop Physiology and Ecology department, Hajee Mohammad Danesh Science and
Technology University, Dinajpur during the period of November 2016 to April 2017
to evaluate their tolerance based on physiological traits and yield performance
against water deficit stress. The experiment was laid out in a split plot design with
three replications. The main plot treatment consisted of two water regimes (well
water condition and water deficit stress) and five wheat genotypes (BARI Gom 26,
SATYN 2, SATYN 11, SATYN 12, SATYN 31) were allotted as sub plot
treatments. Wheat genotypes- SATYN 2, SATYN 11, SATYN 12 showed greater
stability of flag leaf chlorophyll, greater ability to retain water in leaf, higher level of
proline in flag leaf and kernel compared to BARI Gom 26 and SATYN 31 under
water deficit stress condition. Longer grain growth duration, better yield components
such as spikes m-2, grains spike-1, grain dry weight spike-1 and thousand grain weight
under water deficit stress contributed to better tolerance of SATYN 2, SATYN 12
and SATYN 11. The order of tolerance based on grain yield was SATYN
11(0.15)>SATYN 12(0.37)>SATYN 2(0.69)>SATYN 31(1.37)>BARI Gom-26
(2.13). | en_US |
