Extended Data Fig. 2: Root yield under heat stress conditions of 1973 sweetpotato cultivars.
From: Intraspecific diversity as a reservoir for heat-stress tolerance in sweet potato

The cultivars were grouped according to their flesh color: orange (including dark orange, intermediate orange and pale orange), cream (including dark cream and cream) and yellow (including dark yellow and pale yellow). P-values refer to a Wilcoxon test. Strongly pigmented cultivars with anthocyanins were discarded due to their low occurrence in the data set. All root yields are expressed on a log scale.
