Assessment of Gene Flow to Wild Relatives and Nutritional Composition of Sugarcane in Brazil

Abstract

. A 2-year study on eight nutritional composition traits of the 20 main sugarcane cultivars cultivated in Brazil was carried out in six environments. The minimum and maximum values obtained were, in percent: moisture (62.6-82.5); sucrose (9.65-21.76); crude fiber (8.06-21.03); FDN (7.20-20.68); FDA (4.55-16.90); lipids (0.06-1.59); ash (0.08-2.67); and crude protein (0.18-1.18). Besides a considerable amount of genetic variation and plastic responses, many instances of genotype-by-environment interaction were detected.
