Interpretive Summary:

Technical 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 higher lysine and tryptophan content. QPM lines BQPM9, BQPM10, BQPM11, BQPM12, BQPM13, BQPM14, BQPM15, BQPM16, and BQPM17 were developed at Iowa State University to address the lack of QPM lines adapted to the U.S. Corn Belt. These lines originated from crosses made between two QPM lines (CLQ06901 and CLRQ00502) and eleven B lines (B91, B95, B97, B98, B99, B100, B113, B114, B104, B109, and B110). Increased lysine and tryptophan content, presence of the o2 mutation, and agronomic performance were used as selection criteria in the development of the 9 BQPM lines herein released. Of the 39 BQPM lines produced, 9 were selected for release.
