| Abstract: | This paper is concerned with the consequences of variations in the quantities that specify a programme of selection based upon yields, and in particular with the overall intensity of selection, the manner in which this is compounded of fractions selected in successive seasons, the total area or other measure of resources expended upon field trials, the allocation of this total between successive seasons, and the total number of sesons or stages over which selection is spread.
