The genetic relationship among 50 fruiting-mei (Prunus mume Sieb. et Zucc.) cultivars from China and Japan was investigated using 767 amplified fragment length polymorphism (AFLP) and 103 single nucleotide polymorphism (SNP) markers. The polymorphism among the cultivars was 69.77% based on EcoR I + Mse I AFLP primer pairs. The sequence alignment of 11 group sequences derived from 50 samples yielded 103 SNPs with a total length of 3683-bp genomic sequences. Among these SNPs, 73 were heterozygous in the loci of different cultivars. The SNP distribution were: 58% transition, 40% transversion, and 2% InDels. There was also one tri-nucleotide deletion. Both AFLP and SNP allowed the evaluation of genetic diversity of these 50 fruiting-mei cultivars; however, the two derived cladograms have some differences: 1) all the cultivars formed two sub-clusters (1A and 1B) within cladogram based on AFLP polymorphisms, and there were three sub-clusters (2A, 2B and 2C) formed in the cladogram based on SNP polymorphisms; and 2) most cultivars from G-F, Y-H-S regions and Japan are grouped in cluster 1A and 18 (78.26%) out of 23 cultivars from J-Z origin are grouped in cluster 1B in the cladogram generated based on AFLP polymorphisms. The results show cultivars from Japan are clustered within cultivars from China and supports the hypothesis that fruitingmei in Japan was introduced from China in the past. Cultivars from J-Z region of China have higher genetic similarities. Cultivars from G-F and Y-S-H regions have lower genetic similarities and suggest more germplasm exchanges in the past.

Random amplified polymorphic DNA (RAPD) markers are widely used for evaluating the genetic relationship of crop germplasm. Five different landraces of yacon (Smallantus sonchifolius (Poepp. and Hendl.) H. Robinson; Asteraceae) collected in various countries and showing different morphological traits were investigated using a total of 61 decamer primers. A total of 282 RAPD markers were scored and 28.7% of them were polymorphic at least within landraces. RAPD markers generated by one primer (OBP14) discriminated between all landraces. Markers were used to calculate genetic similarity coefficient and to build a dendrogram representing the genetic relationship between analysed landraces. The results suggest that RAPD markers could be used as a reliable tool to perform fingerprinting studies in Smallantus sonchifolius genome. This is the first report on the use of RAPDs to evaluate genetic distance and to distinguish between different landraces in yacon.

The genetic relationship of 96 palmyrah palms, consisting of 24 indigenous accessions from Tamil Nadu and Andhra Pradesh, was investigated using Random Amplified Polymorphic DNA (RAPD) markers. Hundred and eighty primers were used initially to identify the polymorphic primers in six random samples and 10 polymorphic primers were selected to amplify the 96 palms. These 10 primers produced a total of 112 reproducible bands and out of them, 41 fragments (36.6 %) showed polymorphism.  The number of bands produced with each primer varied from seven to 15 with an average of 11.2 bands per primer.  The percent polymorphism ranged from 7.7 to 71.4 with an average of 37.4 per cent when all the primers were taken collectively.  UPGMA grouped all the accessions into two major clusters at 0.85 similarity value. The highest similarity value (0.96) was observed between the accessions KLKM-8 and THY-54 and the lowest similarity value (0.782) was obtained between ANBI-17 and RCML-11. The relatively low polymorphism suggests a narrow genetic diversity of palmyrah populations from which the present accessions have been derived and maintained over the years.
