|Abstract:||Seven selected doubled haploid lines, from each of three cycles (C0, C1, C2) of a diallel recurrent selection program, the seven original parents and two check cultivars were evaluated in replicated hill and row plots at two locations in Ontario in 1988 and 1989. Comparison of hill and row plots using means ranges, coefficient of variation, repeatability and correlations among traits indicated that grain yield, days to heading plant height and powdery mildew resistance could be evaluated with similar accuracy and precision using either of the methods. Regression of row plot yield on hill plot yield was positive and highly significant showing a strong relationship between the two plot types for grain yield. Selection efficiency in hill plots was high for all the traits. The percentage of lines with similar performance for yield in both the plot types was high. The hill plot method appears to be a useful technique for evaluating homozygous lines for yield and other agronomic traits in a doubled haploid recurrent selection program in six-row barley.|
