Introduction and utilization of maize germplasm with improved protein quality

, : Introduction and utilization of maize germplasm with improved protein quality. Crop Genetic Resources ( 4): 14-16

Some opaque-2 germplasm resources of the QPM (quality protein maize) type were introduced into China from CIMMYT in 1984. By using the modifier gene m, new elites of the QPM type were selected from crosses between QPM material and o2 lines, such as Qi 205 (Sui Ai 141 Zhong Xi 017 S3 X Population 70 QPM) and Qi 206 (Zhong Xi 091va35 S6 X Pool 31 QPM), with lysine contents of 0.4% and 0.42%, respectively.
