Abstract
Breeding for waterlogging tolerance is an
important and challenging objective in high
rainfall areas across many countries in the
world, as evaluation of the tolerance in the field
is difficult and not reliable. Molecular markers
can be effectively used in a breeding program
to indirectly select waterlogging tolerance.
In this study, 172 doubled haploid (DH) lines
originating from a cross of YuYaoXiangTian
Erleng (YYXT) and ‘Franklin’ were used
to identify the quantitative trait loci (QTL)
controlling waterlogging tolerance. For the
purpose of comparing QTL from different DH
populations, a consensus map was constructed
using six different populations. A total of four
QTL were identified, which controlled 6.2 to
30.1% of the phenotypic variation. Among these
QTL, one located on chromosome 6H was not
identified in previous studies. Two of the QTL
were located at similar positions to QTL for
salinity tolerance that had been reported earlier.
Further analysis showed some relationships
between waterlogging and salinity tolerance.
Therefore, waterlogging and salinity tolerance
can be improved simultaneously by marker-assisted
selection.
