Flower circumference and flower number QTLs position in recently developed OO lily population

Linkage maps are the framework for the use of genetic markers in breeding programs. In this experiment two widely uses markers were applied to find the loci of some important ornamental traits in lily flowers. The final F1 population to create a linkage maps was 100 individual. The genetic linkage maps were constructed using the CP (out breeder full-sib family) model of JoinMap4 software. Consensus and family linkage maps with all markers were used to carry out a preliminary analysis of productive related QTLs for flower circumference and flower number. The results of experiment showed that there are 8 strong QTLs for the flower number (FN1- FN8). 7 of them were located on the linkage group 2 (LG-F1P2) of the F1 hybrids and 1 was in the LG-M9 of the maternal maps. In the linkage group 2 of the F1 hybrids the QTLs were located near to the following markers: one QTL was between primer combination of E-GGG/M-CGA-2 and E-GGA/ M-TTG, one was on the primer combination of E-GGA/ M-TTG, two QTLs were between E-GGT/M-CGC-4 and E-CGC/M-CGC-4 primer combinations, one QTL was on the primer combination of E-GCT/M-CGA-3, one QTL was on the E-GCT/M-CGA-b primer combination and one QTL was on the primer combination of E-GGC/M-CGC-c. In the maternal maps FN8 QTL was placed between E-CGA/M-CGG-1 and E-GGC/M-CGT-5 of the linkage group 9 (LG-M9). For the flower circumference (flower size when bloomed fully) (FC) the strong QTLs were not found and just one QTL was mapped on the LG-M10 of the maternal maps and it was placed between E-GGG/M-CGA-a and E-GTT/ M-CGT-8 primer combinations.
