The disclosure of the genotypic value in the case of heterogeneous growing conditions,rvable phenotypic values. Variation of the phenotypic values is due to variation of genotypic values as well as variation in the growing conditions. The amount of variation in growing conditions is shown by the (phenotypic) variation appearing in the absence of genetic variation, i.e. the phenotypic

The size and shape of the test plots, area is ‘somewhat large’. Then the trial field contains relatively better and poorer sections. These sections may change in time; their contours may depend on the crop. When evaluating candidates the breeder should try to make allowance for this source of variation. This is only possible in as far

Random variation of allele frequencies,plies to all loci in the case of maintenance of accessions in the absence of selection. Such accessions may constitute collections at breeding institutions or gene banks. It also applies to certain loci for populations that are under selection pressure.

Assortative mating and disassortative mating,for the trait will therefore tend to be similar With . there is a negative phenotypic correlation between the mating plants with regard to the considered trait: the mating plants resemble each other less than plants belonging to pairs of random plants.
