Summary A set of 11 inbred lines of grain maize and generations derived from them were grown at a latitude further north than the generally accepted limit of the crop in the U.K. Analyses of variance for harvesting time, number of kernels and final plant height showed significant differences between the inbred lines and between their F1, F2 and backcross generations. A- and C-scaling tests or the joint scaling test were used to analyse the means of parents, F1, F2 and the two backcross generations for 8 reciprocal crosses. These tests showed that for all the crosses the addivite-dominance models were adequate for the characters. i.e. there was little or no evidence of non-allelic interactions. There was some evidence for heterosis for number of kernels and plant height, that of number of kernels being particularly impressive.
