Description:
|
This is a genetic linkage map on an inter-specific cross between Myrobalan plum ( Prunus cerasifera Ehrh) clone P.2175 and the almond ( Prunus dulcis Mill.)-peach ( Prunus persica L. Batsch) hybrid clone GN22 ['Garfi' (G) almond x 'Nemared' (N) peach]. This three-way interspecific Prunus progeny was produced in order to associate high root-knot nematode (RKN) resistances from Myrobalan and peach with other favorable traits for Prunus rootstocks from plum, peach and almond.The Ma gene and 93 markers [two sequence characterized amplified regions (SCARs), 91 SSRs] were placed on the P.2175 Myrobalan map covering 524.8 cM. The R(MiaNem) gene, the Gr gene controlling the color of peach leaves, and 166 markers (one SCAR, 165 SSRs) were mapped to seven linkage groups instead of the expected eight in Prunus. |
