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

Abstract

A germplasm release representing 8 selections of Salpiglossis sinuata L. (velvet flower), all free of the cleistogamous character which inhibits corolla development, is being made by the Purdue University Agricultural Experiment Station. Five of the selections are diploid (2n = 44) and 3 are tetraploid (2n = 88).

crops with enhanced traits such as size, vigor, and metabolite content ( Alexander, 2017 ; Lehrer et al., 2008 ; Sattler et al., 2016 ; Wang et al., 2016 ; Xu et al., 2014 ). Tetraploids are polyploids that contain four sets of chromosomes. Compared

Abstract

A tetraploid of Gerbera jamesonii Bolus ex Hook, obtained from colchicine treatment of seed is characterized by increased vegetative and flower size. The tetraploid plant is fertile and produces tetraploid seedlings following self-pollination.

. 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

changes, and limited attention has been given to the regeneration ability during in vitro culture and active phytochemicals such as polysaccharide. We believe that in addition to morphological changes, polyploidized D. officinale , such as tetraploids

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
