Technical Abstract: Technical Abstract: Selection for productive sugarcane (Saccharum spp.) cultivars in Florida has been more successful for organic than sand soils. The objective of this study is to determine if there are easily measured traits of sugarcane that can help determine if a genotype will be productive on sand soils in Florida. Thirty-two genotypes were planted as split plots in a randomized complete block design in a field with a Margate sand soil. Main plots were no added soil amendment or about 15 cm of added mill mud. Traits to be studied include plant height, SPAD, stomatal conductance, and leaf chlrophyl fluorescence. It is hoped that this study will identify traits that can be easily measured in the early stages of a sugarcane cultivar selection program with up to 15,000 genotypes. Also, we hope to determine if these traits can be measured on these genotypes planted in an organic soil and still predict performance on a sand soil.
