  • ABSTRACT

    Asian plum (Prunussalicina L.) is as peach a model species in terms of its diploid genome and presence of high value genotypes with high diversityin terms of fruit quality. The objective of this project is to study the genetic and molecular bases of the different traits associated to fruit quality, and blooming and ripening time. We have evaluate phenotypically a segregant population of 150 individuals for 3 years (’98 -99 genotype’ X ‘Angeleno’). We have built a genetic linkage map with microsatellite markers (SSRs) previously designed in other Prunus species.Data obtained through GBS will allow us to saturate much more the genetic linkage maps with new SNPs. In addition, we will sequence by RNA seq (cDNA) both parental allowing a much more acurate localizations of markers in the map. These presented genomic strategies have the final objective of developing specific molecular markers linked to traits associated to fruit quality for be used in our own program.

  • MAIN OBJECTIVE:

    Study of the genetic and molecular bases of traits of Asian plum for their use as molecular markers for performing marked assisted selection.

  • SPECIFIC OBJECTIVES

    • Study of the inheritance of the main physiological, physical and biochemical traits related to fruit quality in Asian plum
    • Mapping of genetic linkage through the use of type markers SSRs and SNPs
    • Identification of QTLs associated with the expression of importante traits associated to fruit quality
    • Design of markers from known sequences in Asian plum for doing marked assisted selection os the species
