H. Della Coletta et al., The use of random amplified polymorphic DNA to evaluate the genetic variability of Ponkan mandarin (Citrus reticulata Blanco) accessions, GENET MOL B, 23(1), 2000, pp. 169-172
RAPD analysis of 19 Ponkan mandarin accessions was performed using 25 rando
m primers. Of 112 amplification products selected, only 32 were polymorphic
across five accessions. The absence of genetic variability among the other
14 accessions suggested that they were either clonal propagations with dif
ferent local names, or that they had undetectable genetic variability, such
as point mutations which cannot be detected by RAPD.
