KT215LC is a late-maturing, high-yielding variety with superior black shank resistance. It has a race 0 resistance of 10 and a race 1 resistance of 9. Note that even though the resistance to black shank is very high in KT 215LC, it is not immune to race 1. In areas with heavy race 1 black shank pressure, fungicides are still recommended for KT 215LC. (see Disease Management section of ID-160). It also has high resistance to Fusarium wilt and black root rot. It lacks the blue mold tolerance of KT 206LC and has no resistance to tobacco mosaic virus or the virus complex. Yield potential, stalk size, and growth habit, are similar to KT 209LC, KT 206LC and KT 204LC. Cured leaf quality has been acceptable and comparable to other recently released varieties. This variety should be used in fields where black shank and Fusarium wilt occur together. The lack of virus resistance is a concern that should limit widespread general use of this variety.

KT-215 LC has shown a tendency to "fire-up" in the top if left in the field more than 5 weeks after topping.
