- Keystone Resistant Giant (Not in Capsi yet)

Bosland’s 2010 HortScience release and NMSU Circular 706 both name Keystone Resistant Giant and Early Jalapeño as the founding pair, then a backcross to Early Jalapeño and five generations of single-plant selection. The line was released open-pollinated in 2010.
