Grain protein accumulation during grain development was studied as a function of defoliation at anthesis in barley ( Hordeum vulgare L.) genotypes grown under pot culture and non limiting nitrogen conditions. The data indicates that per cent grain protein did not decrease proportionally despite 50 % or more decrease in grain yield per plant. These data support the contention that shrivelling need not result in proportional increase in grain protein %. The data also suggests that accumulation of grain protein and carbohydrate during the grain development may not be negatively associated. The data also brings about the importance of grain protein yield per plant as a useful parameter for breeding high grain protein genotypes.
