Narrative

Has red cobs. Has above average early vigor, upright and dark-green leaves, green silks, 3-5 primary tassel branches, 16-18 rows of semi-dent yellow and long kernels. Its maturity, plant and ear height are similar to B73. Flowers 72 to 78 days after planting. Its plants are 161 to 181cm tall, and ear height is 55 to 80 cm. The husks fully cover the ears. It has low leaf firing and tassel blasting when the temperatures are above 38C, indicating they have good heat tolerance. It has moderate resistance to corn earworm, low percentage of molded kernels. It has improved drought tolerance. The silking and pollen shedding are well synchronized and usually the silking is one day ahead of pollen shedding. Under severe drought stress, it has significantly lower barren plants, better seed setting, lower grain mold, and better stay green than other tested lines. It is susceptible to mites. Has been evaluated in combinations with public lines, Holden's lines and breeding lines in multiple environments in Texas and Mississippi. The best combinations are with B110, B113, and LH200, which yielded equally or significantly better than commercial hybrids. The hybrids have large kernels and low earworm feeding damages, grain molds and aflatoxin contamination. This line can be used as a parental line for producing hybrids or as a germplasm for further breeding.
