Sweetpotato cultivar, soil and storage effects on root flesh colour
An important aspect of contemporary food production systems is the requirement for product consistency. This study examined root flesh colour in sweetpotato (Ipomoea batatas (L.) Lam.) as determined by the interaction of genetic and environmental factors. The development of cultivars differing in root colouration has made an essential contribution to diversifying the sweetpotato industry,but considerable colour variation may occur within a cultivar. The objective of this project was to explore the relative contributions of cultivar,soil type and storage duration to root flesh colour. Cultivars provided the broadest range of responses during storage, in-both direction and rate of flesh colour change. The effect of soil treatments on root flesh colour was established at harvest,with colour changes showing the same general pattern during storage,regardless of soil type. Root flesh colour changed during storage, generally becoming slightly darker,more yellow to yellow/orange and duller. While major trends were established in this project, more work is required to construct predictive models and investigate the mechanism by which soils modify root colour development.
