| analysis of genetic diversity in chinese sweetpotato [ipomoea batatas (l.) lam.] germplasm using dna amplification fingerprinting. | the genetic diversity and evolutionary relationships in a representative sample of chinese sweetpotato collection were assessed using the dna amplification fingerprinting approach. dna fingerprint profiles were developed for all 42 accessions tested. there were 19-26 bands for each accession and an average of 20.7 such bands were polymorphic. chinese sweetpotato germplasm tested exhibited a high degree of genetic diversity. phenetic analysis revealed five major clusters with the following compon ... | 1998 | 12296360 |
