Abstract

The discovery of the opaque2 (o2) mutation and o2 modifier genes in maize (Zea mays L.) has resulted in the development of Quality Protein Maize (QPM) lines with increased lysine and tryptophan content. The QPM lines BQPM9 (Reg. No. GP-584, PI 671795), BQPM10 (Reg. No. GP-585, PI 671796), BQPM11 (Reg. No. GP-586, PI 671797), BQPM12 (Reg. No. GP-587, PI 671798), BQPM13 (Reg. No. GP-588, PI 671799), BQPM14 (Reg. No. GP-589, PI 671800), BQPM15 (Reg. No. GP-592, PI 673348), BQPM16 (Reg. No. GP-590, PI 671801), and BQPM17 (Reg. No. GP-591, PI 671802) were developed jointly by Iowa State University and the USDA-ARS to address the lack of QPM lines adapted to the US Corn Belt. These lines originated from crosses made between two QPM lines from the International Maize and Wheat Improvement Center (CIMMYT) (CLQ06901 and CLRQ00502) and six inbred lines released by Iowa State University (B91, B97, B98, B99, B100, and B113). Increased lysine and tryptophan content, characteristics associated with the presence of the o2 mutation, and agronomic performance were used as selection criteria in the development of the nine BQPM lines released herein.
