Figure 4.
Agglomeration (Ward method; Dice coefficient) analysis of the R, PSE, DSE and TSE sets of regenerates based on AFLP and metAFLP markers. Cluster significance (dotted line) determined on the basis of pseudo-F statistics with significance level p < 0.05 (R—donor plant; PSE—somatic embryos obtained through indirect somatic embryogenesis; DSE—secondary somatic embryos induced on the hypocotyls of PSE; and TSE—somatic embryos obtained through direct somatic embryogenesis from DSE).
