Product Overview

With great yield potential and quick drydown, LH 2642 RR will set the bar high for performance and agronomic stability under 79 RM. Higher plant populations are necessary to achieve maximum yields of heavy test weight grain on its determinate ear type. A medium-tall plant with very good early vigor, stalk, and root ratings combined with rapid drydown makes LH 2642 RR a top choice for northern growers.
