Abstract	F1 plants between two intervarietal chromosome substitution lines of European spring wheat varieties, 'Sicco' ('Chinese Spring 5B') and 'Highbury' ('Chinese Spring SB'), were used to produce 114 doubled haploid lines, 45 by the Hordeum bulbosum technique and 69 by anther culture These two sets of lines were characterized for variation at a range of morphological, isozyme and RFLP marker loci, and genetic maps were developed with emphasis on chromosomes 6B, 7A, 7B and 7D. A subset of lines, scored for production traits in field trials in 1986 and 1987, were analysed for quantitative trait loci (QTL). The performance of the lines for the quantitative traits studied showed no overall differences due to the method of production of the lines. QTL were located on the linkage map for ear emergence time, height, tiller weight, yield and 50-grain weight using four analytical methods. Many of these effects showed genotype X year interaction.
