Haploid plants are typically sterile and their chromosome number needs to double to develop into fertile diploid homozygous plants. To identify haploid plants among the F1 offspring of the YJX1 × I Cldmp4 i cross, we looked for green fluorescence in peeled seeds as an indicator of diploid hybrid seeds (Figure 1c).
