The changing climate is altering timings of key fruit developmental and ripening processes and increasing the
occurrence of fruit defects. This work aimed to expand the knowledge generated previously on the genetic control
of the ripening process using a biennial x biennial raspberry F1 population (Latham (L) x Glen Moy (GM) (LxGM)),
in this case by examining development in a biennial x primocane F1 population (Glen Fyne (GF) x Autumn
Treasure (AT) (GFxAT)). The aim was to identify Quantitative trait loci (QTL) and genome locations associated
with the process of development from flower bud swell to ripe fruit, to understand how developmental control in
this population differs from that in the LxGM population previously studied. The progeny from this biennial x
primocane population all exhibited primocane fruiting completing their lifecycle in a single season. QTL .. View More»
