Zea mays
L. subsp.
mays
Texas, United States
NC7
2003
DEVELOPED
Breeding material
Yellow-grain line with Southern U.S. adaptation. Combines well with both non-Iowa Stiff Stalk Synthetic lines (non-BSSS) and tropical or subtropical lines. Flowers about 1 day earlier than B73 in College Station, TX. Ears have 14-16 kernel rows and white cobs. Kernels light yellow and dent. Plants shorter than B73 with intermediate ear placement and good stalk quality. Tassels small and erect. Intermediate pollen shedder, a good seed parent and has good anthesis-silking synchronization. Good general combining ability, particularly with non-BSSS lines and subtropical or tropical yellow lines. Combined well with (LH200/LH198), a BSSS tester, and CML285. Susceptible to corn earworm (Helicoverpa zea) and southwestern corn borer (Diatraea grandiosella). The response to aflatoxin accumulation of hybrids under inoculation with Aspergillus flavous has been variable.
