Cerel Grain Protein Improvement615182Summary: Calculations, based on data on maize and barley, are presented which suggestthat additonal nitrogen requirements may be a serious limitation to breeding forincreased protein yield per unit area. However, under unchanged fertilizer conditions, protein yield may still be increased by 2 methods: (1) by improved Nuptake from the soil, and (2) by improved N mobilization and translocation from vegetative organs to the grain. It is further calculated that breeding for improved protein quality, that is, a changed amino acid composition, should not significantly affect N requirements.Collection: Reprints Collection
