Understand yield formation

Yield =

bull OSR yield formation is quite well understood (Berry amp Spink 2006)

bull Yield is sink limited bull must maximise number of seeds set

bull Optimum canopy size at floweringbull Prolonged canopy survival to increase oil

bull Few stem reserves translocated to seed

bull Ultimately maximising capture amp conversion of primary resources (light amp water) is critical

bull Some phases of growth more important than others

Understand yield formation

bull The OSR YEN dataset will have great valuebull Which will increase each yearbull Data base will need careful management

bull Identify the most common factors constraining yields in the UKbull Enabling research to be correctly focussed

bull Identify husbandry practices associated with high yields

bull Identify which plant traits must be improved

Summary

bull Canopy management important for maximising yield ndash optimal pod number and maximum seed number

bull Oilseed YEN initiated to identify innovators and increase understanding of yield drivers

bull Estimate potential yields and understand yield limitations

    Yield =

    bull OSR yield formation is quite well understood (Berry amp Spink 2006)

    bull Yield is sink limited bull must maximise number of seeds set

    bull Optimum canopy size at floweringbull Prolonged canopy survival to increase oil

    bull Few stem reserves translocated to seed

    bull Ultimately maximising capture amp conversion of primary resources (light amp water) is critical

    bull Some phases of growth more important than others

    Understand yield formation

    Estimate Potential Yields Wheat 2015

    thabull Develop a simple but plausible model of yield and oil content

    bull Use model to estimate potential yieldsbull Seed yield oil content gross output

    bull The OSR YEN dataset will have great valuebull Which will increase each yearbull Data base will need careful management

    bull Identify the most common factors constraining yields in the UKbull Enabling research to be correctly focussed

    bull Identify husbandry practices associated with high yields

    bull Identify which plant traits must be improved

    Summary

    bull Canopy management important for maximising yield ndash optimal pod number and maximum seed number

    bull Oilseed YEN initiated to identify innovators and increase understanding of yield drivers

    bull Estimate potential yields and understand yield limitations

          bull OSR yield formation is quite well understood (Berry amp Spink 2006)

          bull Yield is sink limited bull must maximise number of seeds set

          bull Optimum canopy size at floweringbull Prolonged canopy survival to increase oil

          bull Few stem reserves translocated to seed

          bull Ultimately maximising capture amp conversion of primary resources (light amp water) is critical
