use of related variables in explaining genotype-environment interactions

Summary When genotypes are grown in a range of environments several variables are often recorded on the same genotype. Regressing one character on another may not only give useful information about the relation between them but also help to explain genotype-environment interactions observed in the c...

Description
Summary:Summary When genotypes are grown in a range of environments several variables are often recorded on the same genotype. Regressing one character on another may not only give useful information about the relation between them but also help to explain genotype-environment interactions observed in the character of primary interest. Three examples are given in which weight or height is related to a measure of chronological age for a series of cauliflower, lettuce and Nicotiana trials. The conclusions drawn from this technique may be of practical plant breeding importance and also illustrate how the method may be used to assist the interpretation of genotype-environment interactions.
