AI Technical Summary
Technical Problem
Current squash varieties have limited and unstable resistance to Papaya Ringspot Virus (PRSV), leading to significant agricultural losses.
Method used
Development of novel Cucurbita pepo squash plants with increased PRSV resistance by introgressing a semi-dominant QTL allele from Cucurbita ecuadorensis, located on chromosome 10, and using molecular markers for marker-assisted breeding.
Benefits of technology
The introgressed sequence provides enhanced resistance to PRSV, improving economic and commercial efficiency in squash cultivation by reducing virus incidence and impact.
