Fig. 2. Performance of genotypes in Exp. 3 for: (a) Color (I.C.₄₂₀) in 2000 versus 2001, (b) color at 1% impurity in 2000 versus 2001, (c) color at 1% impurity versus mean color averaged across 2000 and 2001, and (d) amino N levels in 2000 versus 2001. In this experiment genotypes were tested across three N rate treatments and two time of harvesting treatments in a plant crop (2000) and ratoon crop (2001). Genotype x N rate or time of harvesting effects were not significant and the average of genotypes across treatments in each year are shown here. Vertical and horizontal bars indicate standard errors.
