9, respectively. The LOD value in
these DTLs was between 3.05 and 11.08. The total
phenotypic variation was represented 1 366.1% of
these 20 QTLs, with 44.1% to 89.4% of the single
phenotypic variation.
For the LW trait, 19 QTLs were found in five linkage
groups, which was MLG
-
1, MLG
-
2, MLG
-
8,
MLG
-
9 and MLG
-
11, respectively. The LOD value
was between 3.11 and 14.78. The total phenotypic
variation was represented 1 230.4% of these 19 QTLs
with 54.2%~89% of the single phenotypic variation.
QTLs for the PW trait, six linkage groups were
distributed, which was MLG
-
1, MLG
-
2, MLG
-
3,
MLG
-
7, MLG
-
8 and MLG
-
9, respectively. The
single phenotypic variation presented that each QTL
had larger difference, the minimal variation in the
qPW
-
2
-
9
was55.3%, and the maximal in
qPW
-
2
-
11
was 88.7%. Therefore, the total phenotypic variation
was 1317.8% in total 21 QTLs.
1.4 QTL analysis of the AFLP linkage group in the
maternal parent
Phalaenopsi
Total twenty-eight QTLs conferring the three horticultural
traits LL, LW, PW were detected, and they distributed
in five linkage groups (Table 4; Figure 3).
Ten QTLs for the LL trait were detected in five
linkage groups, they were FLG
-
1, FLG
-
2, FLG
-
3,
FLG
-
6 and FLG
-
9, respectively. The LOD value was
between 3.11 and 14.78. The phenotypic variation was
represented larger difference in each QTL had, the
minimal variation in the
qLL
-
3
-
8
was 57.7%, and the
maximal in
qLL
-
2
-
4
was 76.3% The total phenotypic
variation was explained 1 317.8% in 10 QTLs.
For the LW trait, eight QTLs were found in three
linkage groups, which was FLG
-
1, FLG
-
3 and FLG
-
6,
respectively. The LOD value was between 3.11 and
