Abstract
The objective of the present work was to study the density and distribution of sugarcane root systems in a multi-environment trial. Experiments were conducted at three soils in the South-Eastern region of Cuba, with 11 sugarcane cultivars. Measurements of root diameter and root density (root numbers/cm3) for fine (FD), thick (ThD) and total (TD) roots were taken using the profile wall method. The root system was evaluated in squares of 20 x 100 cm up to 80 cm depth below the ground surface. Cane yield data (t/ha) and its relations with root system measurements were analysed. Genotype by environment interaction was identified using the AMMI model. Results showed significant (p<0.05) response for root density across genotypes, soils, depths and all interactions. Root depth was the major source of variation. Percentage of total root density was variable from 42.6-55.5% for 0- 20 cm depth, dropping to 5.6-11.7% for 60-80 cm depth. Genotypes C86-12, C86-156, B7274 and C88-380 showed similar patterns for t/ha and TD. Moderate but significant (p<0.01) correlations were found between t/ha and FD, ThD and TD.
