Raising yield potential in wheat.
Recent advances in crop research have the potential to accelerate genetic gains in wheat, especially if co-ordinated with a breeding perspective. For example, improving photosynthesis by exploiting natural variation in Rubisco's catalytic rate or adopting C(4) metabolism could raise the baseline for yield potential by 50% or more. However, spike fertility must also be improved to permit full ut...
متن کاملRaising yield potential of wheat. II. Increasing photosynthetic capacity and efficiency.
Past increases in yield potential of wheat have largely resulted from improvements in harvest index rather than increased biomass. Further large increases in harvest index are unlikely, but an opportunity exists for increasing productive biomass and harvestable grain. Photosynthetic capacity and efficiency are bottlenecks to raising productivity and there is strong evidence that increasing phot...
متن کاملRaising yield potential of wheat. III. Optimizing partitioning to grain while maintaining lodging resistance.
A substantial increase in grain yield potential is required, along with better use of water and fertilizer, to ensure food security and environmental protection in future decades. For improvements in photosynthetic capacity to result in additional wheat yield, extra assimilates must be partitioned to developing spikes and grains and/or potential grain weight increased to accommodate the extra a...
متن کاملRaising yield potential of wheat. I. Overview of a consortium approach and breeding strategies.
Theoretical considerations suggest that wheat yield potential could be increased by up to 50% through the genetic improvement of radiation use efficiency (RUE). However, to achieve agronomic impacts, structural and reproductive aspects of the crop must be improved in parallel. A Wheat Yield Consortium (WYC) has been convened that fosters linkage between ongoing research platforms in order to de...

season, while potentially costly, could significantly increase NUE. Current nitrogen use efficiency (NUE) of cereal crop production Recently, methods for estimating winter wheat N reis estimated to be near 33%, indicating that much of the applied quirements based on early season estimates of N uptake fertilizer N is not utilized by the plant and is susceptible to loss from and potential yield w...
