Nalini, 1972 ), and the cause(s) of such in vitro germination failures remain to be identified. Thus, pollen stainability has been the primary parameter used in lantana pollen viability assessment. This study was conducted to determine the ploidy levels
Genome size, chromosome number, and ploidy level are important biological parameters for plant breeding, systematics, and evolution. Since the first published chromosome counts of plants in 1882 ( Garbari et al., 2012 ), ≈25% of angiosperms have
to be a more cost-effective way of producing a large number of markers ( Mueller and Wolfenbarger, 1999 ). In this study, we use AFLP, in conjunction with ploidy analysis and plant phenotype, to elucidate the reproductive mechanisms of Aronia
release or bloom delay techniques ( Naor et al., 2003 ). Kiwifruit ( Actinidia ) is a functionally dioecious liana with variable ploidy levels (e.g., diploid, tetraploid, and hexaploid) ( Huang et al., 2000 ; Li et al., 2010 ). Most current kiwifruit
, depending on taxonomic treatment ( Li, 2011 ; Suh et al., 2000 ; Zhang et al., 2010 ). Although many teams are working on clarifying taxonomy, relatively little has been reported on genome size and ploidy level within the genus. Three original papers
Phlox (Polemoniaceae) is a phenotypically diverse genus with substantial interpopulation differentiation for numerous morphological characters and ploidy; it includes ≈65 species with centers of diversity in the eastern and western United States
successfully used in warm-season grasses ( Harris-Shultz et al., 2013 ; Mulkey et al., 2013 ). With the interest in little bluestem, and the horticultural planting of a few recommended cultivars, we aimed to determine ploidy level and to create SSR markers to
lantana in Australia also differed dramatically in pollen viability and ploidy level/chromosome number. The weedy form had ≈65% pollen stainability and was a tetraploid with 2 n = 4 x = 48 chromosomes, whereas the garden form had extremely low pollen
breeding work, ploidy manipulation is a valuable tool for improving crop quality or production and polyploids promote evolution history significantly ( Adams and Wendel, 2005 ; Leitch and Bennett, 1997 ; Otto and Whitton, 2000 ). Polyploidization often
as Cornus ( Shearer and Ranney, 2013 ) and Magnolia ( Parris et al., 2010 ). When combining genome sizes with their corresponding chromosome counts, genome size data can be used to discover ploidy variation among related taxa ( Contreras et al
