tetraploid plants exhibit fully restored fertility for breeding, although the edibility and genetic characteristics of the plants related to health care use have not been noted as differences among the selected materials. The first application of colchicine

. To improve ornamental characteristics, it is important to do researches on breeding of L. maritima (L.) Desv. In this study, we aimed to develop an efficient method to induce tetraploid plants by treating germinating seeds and the apical growing

, Europe, Japan, Australia, and New Zealand ( Thorogood, 2003 ). In the United States, turf-type perennial ryegrasses are commonly used for golf courses, sports fields, lawns, and landscapes. Perennial ryegrass is naturally diploid; however, tetraploids

interactions is currently unknown in potatoes. Commercial potatoes are tetraploid, whereas the high-carotenoid clones identified to date have been diploid ( Brown et al., 1993 ; Lu et al., 2001 ). Ploidy levels can be manipulated through the use of 2n gametes

simplex Wright ( Freyre et al., 2012 ). The key step in ploidy manipulation is chromosome doubling and induction of stable tetraploids, which are the gateway to obtain other ploidy levels (triploids, pentaploids, hexaploids, octoploids, etc.) through

Various techniques have been used to overcome genetic crossing barriers between species in Vaccinium . Tetraploid blueberry plants have been produced by crossing diploid and tetraploid species. The production of unreduced gametes and the

focused on several sets of crosses between clones of Solanum chacoense that were expected to yield a high proportion of triploid clones, the conclusion reflected previous observations that tetraploid × diploid crosses often result in a low seed set. This

. Colchicine is the most widely used chemical agent for chromosome doubling. Tetraploids at frequencies of 83.3% and 80.0% were induced in Xanthosoma sagittifolium when in vitro-grown plants were treated with 1.25 m M or 2.5 m M of colchicine, respectively
