Green flesh worldwide geographic distribution and illumination time of the typical location. a Distribution of 115 cucumber CG lines in different continents based on flesh color data. To understand the distribution easier, we defined group 1, 2 and 3 as white flesh, group 4 and 5 as green flesh. b Part CG lines flesh color showing five different groups. c Illumination time of the wild cucumber latitude (WCL), European cucumber latitude (ECL), North China cucumber latitude (NCCL, same with the experiment location in Beijing) and the experiment location in Sanya. The left red dashed line means the illumination time pattern during the cucumber growing season in Beijing. The right dashed line means the illumination time pattern during the cucumber growing season in Sanya
