Use of GGE Biplot to Evaluate Variety Performance In the Mid-South and Southeast

The interaction of varieties with environments is an important source of variation in cotton variety trials and GGE Biplot is a useful tool to digest and gain some understanding of this GxE interaction. Phytogen conducts a combined elite strains test with both early-mid and full maturity entries uniformly across a broad range of environments in the Mid-South and Southeast. GGE Biplot will be used to analyze the interaction of commercial varieties with the test environments in both 2009 and 2010.
