INTERPRETATION OF THE INDIVIDUAL PERFORMANCE ADJUSTMENT FORMULA IN MASS SELECTION

Abstract

An interpretation is made of the formula that gives adjus ted
plant yields of the actual yields from a mass selecction plot, Y _ij  Y _..+ (Y_ij -Y_i. ), lt is assumed that intra sub-plot envorpnmental variation

is absent or insignificant, thus, adjusted plant yields correspond to the field weights minus the envi ronmental deviation due to the sul­plot estimated by its average yield.
