Abstract
A doubled haploid population, generated from a cross between Franklin and TX9425, were grown in three environments to identify quantitative trait loci (QTLs) controlling plant height. Both parents had similar plant height in autumn sown trials but TX9425 was much shorter in spring sown trials. The DH lines showed a wide range of variations in all the different environments. Three QTLs were found for plant height, including one from Franklin (denso) and one from TX9425 (possibly uzu). A new dwarf gene was also found from the Chinese landrace variety. This new gene was located at the close position to denso and uzu genes and only expressed in late winter or spring sown trials.
