chickpea (Cicer arietinum L.). Water conservation at vegetative&#13;
growth (canopy conductivity and canopy size and development)&#13;
allow plants to increase soil water extraction during grain filling&#13;
and are hypothesised to help chickpea adaptation to water&#13;
limited environments. Plant vigour and water saving traits were&#13;
phenotyped in 232 recombinant inbred lines (RILs), derived&#13;
from a cross between ICC4958 and ICC1882, at 28 days after&#13;
sowing under well water conditions using a high throughput&#13;
phenotyping platform. Different density genetic maps (241-SSRLow&#13;
density, 1007-SSR+SNPs-High density and 1557-SNPs-Ultra&#13;
high density) were used for QTLs identification. Several major&#13;
QTLs (M-QTLs) for plant vigour traits (3D-leaf area, shoot biomass,&#13;
plant height and growth related traits) were identified&#13;
on CaLG04, and co-mapped with previously identified and&#13;
fine mapped major drought tolerance QTL-hotspot region on&#13;
CaLG04 (~300Kb).The canopy conductance trait (e.g Transpiration&#13;
rate) had a M-QTL mapped on CaLG03 using ultra-high&#13;
density bin markers. Plant vigour traits on CaLG04 and canopy&#13;
conductance related traits on CaLG03 provide opportunity&#13;
to manipulate these loci to tailor recombinants having lower&#13;
transpiration rate and high plant vigour. This ideotype might be&#13;
enhancing the water stress adaptation in chickpea. To test this&#13;
hypothesis, a subset of 40 RILs contrasting for vigour and water&#13;
use traits was tested in lysimeters and field under different water&#13;
stress treatments. High vigour low water use lines had higher&#13;
seed yield under severe water stress treatments than high vigour&#13;
and high water use lines, validating the hypothesis.</mods:abstract><mods:classification authority="lcc">Abiotic Stress</mods:classification><mods:classification authority="lcc">Drought Tolerance</mods:classification><mods:classification authority="lcc">Chickpea</mods:classification><mods:classification authority="lcc">Drought</mods:classification><mods:classification authority="lcc">Genetics and Genomics</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2017-02</mods:dateIssued></mods:originInfo><mods:genre>Conference or Workshop Item</mods:genre></mods:mods>
