Two MAIZE (Zea mays L.) (Reg. no. GP125 & GP126) breeding populations developed at the Agricultural Experiment Station, North Dakota State University, were released in 1983 for breeding programs for short growing season areas. Breeder seedstocks are maintained by the North Dakota Agricultural Experiment Station and can be obtained in germplasm quantities from H.Z. Cross, Agronomy Dep., North Dakota State Univ., Fargo, ND 58105. NDSAB (Reg. no. GP125) is a yellow dent endosperm maize synthetic developed by one cycle of full-sib family selection among 100 full-sib families between NDSA and NDSB, synthetics released in 1979 (1). Twenty families were recombined to form the original population, which was then mass selected for three cycles for yield and standability. Equal numbers of seeds from 30 ears (half-sib families) were composited to give an improved population each cycle. Selection intensity was approximately 1%. NDSAB plants are tall with ears borne slightly above midplant. NDSAB is similar in maturity, shelling percentage, and test weight to NDSC, which has been previously described (2). NDSAB is higher yielding than NDSC, but may be slightly more susceptible to root lodging. It is AES300 maturity. NDSF (Reg. no. GP126) is a yellow dent synthetic which was developed by intercrossing approximately 65 inbreds. Parental inbreds were selected for very early maturity and prolificacy. This population was then intermated for two generations. NDSF plants are moderately short with ears placed slightly below midplant. NDSF has higher shelling percentages and test weights than NDSAB. Yields and lodging resistance are similar to NDSC. NDSF is much earlier than either NDSC or NDSAB with an AES 100 to 200 maturity.
