Last week, I checked on shuck split and found that Chetopa, Dooley and Giles had ripened (photos at right and below). The photos reveal that all three of these cultivars are susceptible to pecan scab but the infections did not prevent normal shuck split.
This week, Greenriver, Lakota, and Oswego opened their shucks (photos below). Note how nice and clean the shucks of these three scab-resistant cultivars appear in the photos.
When I was looking for a cluster of Oswego nuts to photograph, I came across a cluster that contained a double nut (photo at bottom of post). Twin nuts originate as two fused pistillate flowers that share a common shuck wall but have separate stigmas and ovaries. At harvest, the twin nuts fall as a pair fused only at the very base of the shell. They often break apart during mechanical harvest.
