Teagasc and IPM Potato Group have recently released a new potato variety which is resistant to potato cyst nematode (PCN). As Stephen Robb reports in the Irish Farmers Journal, the variety is called “Buster” – a new ware or prepack variety that is said to be resistant to both species of PCN that impact potatoes.
Robb writes that its speed of development was greatly assisted by new genomic identification capabilities. According to Dan Milbourne, who spoke at this week’s National Tillage Conference, Buster combines PCN-resistant genes from five parents.
The variety was achieved using a genomic approach called marker assisted recurrent selection (MARS).
