Abstract

Genotype x environment interactions of resistance to clover scorch in Trifoliurn subterraneurn subspecies yanninicum were studied by growing 11 subterraneum clover genotypes at three sites in Western Australia and one site in South Australia. Similar data from the previous year at one site were utilized to study genotype x season interactions. Clover scorch damage was assessed by scoring at fortnightly intervals from which total disease development was calculated. A combination of established methods called by us significant rank order, in which analysis of variance is followed by a ranking process, is developed and discussed. Interactions based on significant rank order are demonstrated, and the implications of these interactions for plant breeding strategies are discussed.
