Comments about the QTL
Publication measured phomopsis seed decay by Phomopsis longicolla, which was defined as the percentage of mature seeds collected 10 days after maturing which showed infection after 4 or 7 days of incubation on Acidified Potato-Dextrose Agar (APDA). See publication for additional details.
Parent_1 was Taekwangkong, Parent_2 was SS2-2
Phomopsis seed decay (PSD) is caused by members of the Diaporthe/Phomopsis genus.
