L.) plants have to rely increasingly on remobilization of previously stored assimilates to maintain grain filling.
In two-year field trials, we studied more than 20 agronomic and developmental traits in 61 wheat genotypes (27 F4:5 families, 17 parents used for the crosses and 17 standards), comparing plants that were defoliated (DP) by cutting off all leaf blades 10 days after anthesis with intact control plants (CP).
In addition, data will be made available to different modelling teams for improving their models.
Field experiments will be carried out, in which wheat plants are exposed to elevated temperature and also to elevated CO2 concentration under sufficient water supply.
In general F4:5 families (FAM), that had been crossed to combine typical breeding traits such as biomass and yield components, showed better tolerance under moderate stress than standards and parents.
