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.

The addition of some herbicides, fungicides and insecticides may increase the intensity of leaf burn and limit the efficacy of the pesticide application.About a ½ percent protein increase has been achieved using this method.Field studies with simultaneo The objective is to improve the quantification of the effect of high temperature or heat stress on grain yield components.In addition, it will be investigated, whether increasing CO2 concentrations enhances or mitigates these effects of high temperature or heat stress on grain yield.
