Crosses in spring barley between parental combinations classified by their G x E interactions as 'similar' or 'dissimilar' were compared for both the expression of heterosis in Fr and for the amount of variation released in F2. Such classification could not reliably identify the most heterotic Ft h
## Abstract Barley was inoculated with conidia of __Aspergillus parasiticus__ NRRL 2999, and at 0Β°C was left to equilibrate at three moisture levels: 17, 20 and 25%. Gamma irradiation at five doses, 0, 50, 100, 200 and 400 krad, was applied to the grain either soon after moisture equilibration (3 d
