“…Overall there is an agreement in that cytogenetic information is necessary to evaluate levels of genomic variation to spatial scale, helping dilucidate taxonomic relationships or to understand patterns on genome size evolution and polyploidization (Soltis & Soltis 2000, Levin 2002, Bennett 2004, Bennetzen et al 2005, Leitch et al 2005, Murray 2005, Leitch et al 2007, Peruzzi et al 2009, Kraaijeveld 2010.…”

Cytogenetic data on Chilean angiosperms have been reported since at least eight decades ago; however, much of this information is disperse in diverse sources and is not readily available as a comprehensive document that allows having a general vision on advances and gaps in this matter. The goal of this paper is to summarize the advances and prospets on cytogenetic studies of the Chilean angiosperms based on compiled publications from 1929 to 2010. We found 78 publications supplied by four groups of Chilean researchers and some foreign specialists. Cytogenetic data have been reported for 139 Chilean angiosperm species (2.8 % of the total), which belong to 58 genera and 34 families. During 2001-2010 there was an increase in the number of publications, being available 40 reports including 95 additional species. Based on these data, we hope that such a trend can be maintained in the next decade if the current research groups and young specialists continue to be interested in the study of native plants.Key words: chromosome banding, chromosome number, genome size, karyotype morphology.

“…In most of plant taxa, ITS and ITS2 showed strong ability of species identification (China Plant BOL Group, 2011; for awful species identification of DNA barcodes in this study. The reliable evidence was that identified ability of DNA barcodes was not ideal in most of taxa belonging to Liliaceae in which genome sizes are generally huge (Leitch et al, 2007). …”

“…Approximately 55 species occur naturally in the southwest and north of China, which is considered to be the global center of wild lily diversity (De Jong, 1974). Molecular analysis indicates that lilies arose in Eurasia, nearly 68 million years ago (Leitch et al, 2007). Lilies have been bred for more than 200 years (Peng, 2002;Cui et al, 2014), and more than 10,000 cultivars have been developed to date (Younis et al, 2014).…”

ABSTRACT. Lily (Lilium spp), which belongs to Lilium, is one kind of monocotyledon. As a perennial ornamental plant with extremely high esthetic, edible, and medicinal value, lily has gained much favor due to its mostly showy flowers of various colors and elegant shape. In this research, we studied experimental materials in a sample of 49 individuals including 40 cultivars, nine species of wild lily, and their variants. The collection of 40 cultivars covered all six hybrids in the genus, i.e., Asiatic hybrids, Oriental hybrids, Longiflorum hybrids, LA hybrids, LO hybrids, and OT hybrids. Genetic diversity and inter-relationships were assessed through analysis of phenotypic characteristics, pollen morphology, and ISSR molecular markers. Quantitative characters were selected to analyze phenotypic variation, with results indicating greater variability in petiole length as compared to other characters. Pollen morphological observations suggested that the largest variation coefficient between all hybrids and wild species was the lumina. ISSR makers demonstrated that both cultivars and wild species possess a high level of genetic diversity. Specifically, the genetic diversity of wild lily was higher than cultivars.
