., 1996 ), and total tuber carotenoids in two Texas environments ( Reddivari et al., 2007 ) have been found to vary among genotypes and environments. In both studies, genotypic effects were greater than environmental or genotype × environmental effects and

lesser extent. A. hypochondriacus grows quickly and is amenable to a single harvest or uproot harvesting, and is well-adapted to short crop seasons and resource-limited environments. A. dubius , cultivated and grown in the wild, is recognized for its
