7.63.The total phenotypic variation was represented
506.8% in these 8 QTLs with 57.8%~69.3% of the
single phenotypic variation.
Ten QTLs for the PW trait were distributed among
four linkage groups, which was FLG

6, respectively. The LOD value was
between 3.76 and 6.29. The total phenotypic variation
was 614.5% of these 10 QTLs, with 56.3%~68.5% of
the single phenotypic variation.
2 Discussions
QTL analysis results showed that the expression of the
traits in
Phalaenopsis
leaves and plant types were
regulated by polygenic loci located in different
linkage groups. Studies have shown that QTLs with
closed traits were often mapped on the same or
adjacent areas. It is common that the genes that have
the closed functions cluster together, (Xiao et al., 1996;
Li et al., 2003; Jiang et al., 2004) and may also be a
universal phenomenon of gene expression and regulation
