Robust 98114W White Popcorn


Robust 98114W White Popcorn

Zea mays
(98 days) F-1 hybrid. Taller, a bit later, higher yielding with larger kernels and ears, and greater ease of popping than the old Robust 21-82W, this midseason white hulless popcorn has great eating quality—crisp and tender, light and flaky. The 6' plants have the stalk strength to survive September storms intact. “Nice long thin ears,” says farmer and consumer member of Fedco’s board Jason Kafka.
