The variability of varieties of sugar cane (Saccharum spp., comm. Hybrids)
Keywords:Sugar cane, Variety, Environment, Interaction, Variability
AbstractResults are presented of a study of yield variability of varieties of sugar cane (Saccharum spp.) in trials over the period 1975-90, in Jamaica. Although there was considerable variation in variety differences between trials, it was not possible to associate these differences with individual centres or environmental conditions. Comparisons with the discriminating power of testing systems for other crops suggest that relatively more testing resources are needed in sugar cane to achieve the same precision.
