“…The genetic variability of phenotypes ranged from 0.07 (T. glomeratum) to 0.61 (T. campestre) with an average of 0.30 based on the polymorphic information content (PIC). Levels of variability in this study were comparable to those of many enzymatic variation studies on Trifolium populations (Kongkiatngam et al 1995;Lange & Schifino-Wittmann 2000;Malaviya et al 2005Malaviya et al , 2008Dias et al 2008b).…”

“…Despite the use of DNA markers, isozyme polymorphism is also used effectively in species delimitation and conservation, genetic relationship between individual populations and closely related species. Sporadic reports within the genus Trifolium based on isozymic studies are available (Kongkiatngam et al 1995;Lange & Schifino-Wittmann 2000;Malaviya et al 2005Malaviya et al , 2008Dias et al 2008b).…”

Medoukali I., Bellil I., Khelifi D. (2015): Evaluation of genetic variability in Algerian clover (Trifolium L.) based on morphological and isozyme markers. Czech J. Genet. Plant Breed., 51: 50-61.Genetic variation within and among fifteen Trifolium species represented by 157 accessions was assessed using morphological and isozyme markers. Most of morphometric characters contributed to the discrimination of the species. No significant relationship between the environment of the collection site and morphological features was detected. The two isozyme systems analysed, esterase (EST) and glutamate oxaloacetate transaminase (GOT), proved polymorphic. Phenotype diversity of isozyme markers ranged from 0.07 to 0.61 with an average of 0.31 based on the polymorphic information content. The pairwise Jaccard's similarity coefficient ranged between 0.10 and 0.60, indicating that the collection represents genetically diverse species. A considerable number of species-specific zymograms were detected which can be used for the species identification. The clustering pattern of isozyme markers was incongruent with the groupings based on quantitative traits. The rich isozyme variability present among the Algerian clover species indicates that they can provide good gene resources for breeding.

“…For plant breeders, the species is attractive due to its qualities as perenity, cold tolerance and tolerance to soils with high aluminum and manganese contents (Kappel, 1967;Moraes et al, 1989). Previous studies with few accessions of the species disclosed a high intraspecific variation when isoenzymatic (Lange and Schifino-Wittmann, 2000), SSR markers and morphoagronomic characteristics (Conterato et al, 2010a) were used.…”

“…However, RAPD markers are largely limited in the analysis of population structure since a complete genotypic determination is hampered by their dominant nature (Lynch and Milligan 1994). In contrast, isozymes as codominant markers are useful to estimate the allelic frequency and population genetic parameters and have proved reliable in genetic studies with red clover natural populations (Hagen and Hamrick 1998, Lange and Schifino-Wittmann 2000, Semerikov et al 2002, Mosjidis et al 2003 and cultivars (Kongkiatngam et al 1995, Yu et al 2001. Different aspects of the diversity can be analyzed by the use of molecular and biochemical markers.…”

-The genetic diversity in the red clover USA core collection was measured by RAPD and isozyme markers, comparing different approaches of isozyme data analysis and comparing the results of RAPD with those of isozymes. A total of 15 isozyme loci and 114 RAPD fragments were analyzed. Genetic diversity measured with RAPD and isozymes was high. The analyses of isozymes as binary data was highly correlated with the allele-frequency approach. There was no correlation between the distance matrices of different markers. Isozyme data grouped the accessions of red clover in four groups. The variation evidenced by AMOVA was higher among and within groups in the populations than at the intra-population level.Results showed the high diversity in the red clover core collection and indicated some populations that could be used in breeding programs of the crop in Brazil.
