Best adapted to the north central United States. Maturity is 69 days from emergence to 50% of plants in silk (1625 heat units); 102 days from 50% silk to harvest at 25% kernel moisture. Plants 178 cm in height (to tassel tip), 56 cm ear height (to base of top ear), 11 cm long top ear internode, no tillers, single ear per stalk, normal cytoplasm. The stalk is of average strength and the roots are fair. Leaves are dark green, 30-60 degrees angle from stalk (upper half), light sheath pubescence, few marginal waves, longitudinal creases absent. Ear node leaf average width of 10 cm at widest point and length of 72 cm. There are 14 leaves per mature plant, separated by relatively short internodes. Anthers are red and extrude from a green glume with red points of dehiscent. Ear is medium in length and has average taper, it is attached to a strong shank of medium length, and has a short husk extension. Kernels are arranged in 16 slightly curved rows. Kernel is thick, dark yellow with a bright yellow cap. Most closely resembles B37, except LH1 is an average of 20% shorter, has a lower ear height by an average of 30%, and it restores C cytoplasm nearly 100% while B37 does not. Silking date is approximately the same but there is some indication that LH1 will dry slightly faster, at least to the 25% moisture level. | 1127095 | PI 644101 |
