Narrative
NDBS21 (R-T)C9 Syn 2 is a unique maize synthetic variety adapted by NDSU for breeding programs developing short-season non-Stiff Stalk (SS) or unrelated inbred lines. It is a unique short-season population that was developed by crossing BSS x BS20 synthetic varieties and then improved by 7 cycles of reciprocal recurrent selection under Iowa conditions. This followed one cycle of stratified mass selection for adaptation to short-seasons and two cycles of half-sib intrapopulation recurrent selection with elite SS industry testers under North Dakota (ND) conditions. NDBS21 (R-T)C9 Syn 2 was tested per se and in hybrid combinations across ND environments and has shown excellent combining ability for grain yield in uniform population hybrids. This population has provided unique short-season inbred lines capable of producing above average grain yield, test weight, and grain quality.
