Abstract
The invention relates to a method to improve breeding in dioecious plants, preferably Asparagus plants, comprising providing a plant in which the functional expression of the dominant suppressor of gynoecium development is disrupted or reduced and introducing said plant in inbreeding, backcross breeding, recurrent backcross breeding or double haploid breeding techniques. Preferably said dominant suppressor of gynoecium development is a gene comprising a DUF247 domain. Also provided are dioeciuos plants in which the expression of this gene is disrupted or reduced.
Claims10
An Asparagus plant in which functional expression of a DUF247 domain-containing protein with SEQ ID NO:2, encoded by a dominant Gynoecium Development Suppressor (GDS) gene having SEQ ID NO:3, or having at least 95% sequence identity to SEQ ID NO:3 is reduced, wherein the functional expression is reduced by disruption of the GDS gene having SEQ ID NO:3 or having at least 95% sequence identity thereto.
