Description:
|
A genetic linkage map of apricot (Prunus
armeniaca L.) was constructed using AFLP and SSR
markers. The map is based on an F2 population (76
individuals) derived from self-pollination of an F1 individual
('Lito') originated from a cross between 'Stark
Early Orange' and 'Tyrinthos'. This family, designated as
'Lito' x 'Lito', segregated for two important agronomical
traits: plum pox virus resistance (PPV) and self-incompatibility.
A total of 211 markers (180 AFLPs, 29 SSRs
and two agronomic traits) were assigned to 11 linkage
groups covering 602 cM of the apricot genome. The
average distance (cM/marker) between adjacent markers
is 3.84 cM. The PPV resistance trait was mapped on
linkage group G1 and the self-incompatibility trait was
mapped on linkage group G6. Twenty two loci held in
common with other Prunus maps allowed us to compare
and establish homologies among the respective linkage
groups. |
