NDEarlyGEM4 (Reg. No. GP‐600, PI 675375), NDEarlyGEM5 (Reg. No. GP‐601, PI 675376), NDEarlyGEM22a (Reg. No. GP‐602, PI 675381), NDEarlyGEM22b (Reg. No. GP‐603, PI 675382), and NDEarlyGEM26 (Reg. No. GP‐604, PI 675383) are new non‐Stiff Stalk maize ( Zea mays L.) populations from the EarlyGEM program. The designation “ND” represents North Dakota for national registration to recognize efforts of germplasm adaptation and improvement at North Dakota State University, Fargo. “EarlyGEM” was added to also recognize all Germplasm Enhancement Maize (GEM) network efforts that made original GEM germplasms available for adaptation to short‐season environments. The North Dakota Agricultural Experiment Station released these populations on 17 Jan. 2014. The North Dakota maize breeding program is the sole genetic provider of EarlyGEM genetic materials. The objective of the EarlyGEM program is to increase the genetic diversity of short‐season hybrids with unique sources of germplasm currently not available in the northern US industry. Seven EarlyGEM inbred lines have been developed from these released populations and have been shared with industry exclusively.
