LH260 has demonstrated sensitivity to Lasso related compounds and acetolactate synthase inhibiting chemicals. Symptoms include the growing of tassels and ears downward as they emerge and increased root lodging.

LH260 is most similar to LH51. The most distinguishing difference is tassel length. LH260 is shorter in tassel length than LH51. LH260 flowers approximately 1-2 days earlier than LH51. The silk color of LH260 is light green while the silk color of LH51 is salmon. There are many more longitudinal creases present on the leaves of LH260 than there are on the leaves of LH51. The leaves of LH260 are shorter, wider and more erect than the leaves of LH51. LH260 exhibits a slight two ear tendency while LH51 exhibits only a single ear tendency.

As a line, LH260 is resistant to corn lethal necrosis, however, this resistance is not carried in its hybrid combinations. It is a very good pollinator, but does not have potential use as a seed parent. LH260 crosses exhibit strong early vigor and are some of the tallest hybrids prior to pollination. During the growing season, the upright leaves of LH260 hybrids create a unique appearance. Although ear placement is high, stalk quality and resistance to stalk rots is very good. Root strength is below average. In general, the late season plant appearance of LH260 hybrids is excellent and test weight has been good.

LH250 is most similar to LH150, but it flowers four days earlier. The leaf margins of LH250 are purple. This characteristic is especially evident on the upper leaves of the plant at anthesis. This characteristic is not noticeable on the leaves of the LH150 plant. The kernels of LH250 have a more flinty or corneous appearance than the kernels of LH150. In some areas LH250 may prove to be an excellent replacement for LH150. The LH250 hybrids produce more uniform ears and less barren plants than the LH150 hybrids. LH250 hybrids perform best when kept in the southern Corn Belt. As compared to LH150, aphids cause fewer problems for LH250.

LH159 most closely resembles LH156. The traits that most distinguish LH159 from LH156 are glume and anther color. LH159 has an unusual leaf morphology where the edge of the leaves tend to fold around the underside of the midrib. This characteristic is especially expressed on the outer half of the blade toward the tip. Another unusual trait in this line is a high frequency of fasciated ears. This trait along with others makes LH159 an unsuitable seed parent. LH159 flowers slightly later than LH150. Like many full season lines, LH159 tends to shed pollen late in the day. LH159 has a white cob.

In hybrid combination, LH159 contributes excellent yield, good grain quality, girthy ears and husk cover. Under moisture stress, LH159 hybrids seemed to perform better than comparable NC258 hybrids.

LH172 hybrids have improved stalk quality and root strength when compared to their LH82 counterparts. Late season plant health is excellent. Hybrid harvest moistures have been up to 1.0% drier than LH82 on the B73 types and similar to 1.0% wetter than LH82 on the B14 types.

LH197 appears to have captured the high yield trait of B84 and has similar root strength to LH132, but LH197 is slightly weaker in stalk strength than LH132. LH197 is slightly better in tolerance to leaf diseases than LH132. LH197 is much improved in tolerance to Stewart's leaf blight compared to LH132. LH197 is taller in plant height and ear height than either LH132 or B84. It also appears to have better seed parent capabilities than both parents. LH197 is adapted over most of the Corn Belt.

When compared to similar LH132 hybrids, LH197 hybrids are higher yielding and similar or drier in harvest moisture. LH197 hybrids are also longer eared, taller in plant and ear height and show increased tolerance to Stewart's Leaf Blight (Erwinia stewartii).
