“…Chromosome numbers are 2 x = 2 n = 80 for H. syriacus and H. sinosyriacus , and 2 x = 2 n = 82 for H. paramutabilis (Niimoto, 1966). The breeding efforts have resulted in several unnamed hybrid experimental lines (Van Huylenbroeck et al, 2000; Kyung and Kim, 2001; Kyung et al, 2001; Eeckhaut et al, 2004) and cultivars, i.e., Daewangchun (Ha et al, 2015); Tahagol Red (Ha et al, 2014), and Woolred (Kang et al, 2015).…”

Herbaceous winter-hardy Hibiscus spp. in the section Muenchhusia, also known as rosemallows, are attractive ornamental plants found in temperate environments. These should not be confused with woody winter-hardy hibiscus (Hibiscus syriacus L. and related species) which have also been intensively used as ornamental shrubs. During the past 70 years, breeders have attempted to create winter-hardy hibiscus hybrids with novel flower colors resembling the distantly related tropical Chinese hibiscus, Hibiscus rosa-sinensis L. Although direct attempts to hybridize winter-hardy hibiscus with the tropical hibiscus have been unsuccessful, new interspecific herbaceous winter-hardy hibiscus hybrids with a palette of novel flower colors commonly found in tropical hibiscus have been recently introduced. In this review, we outline the historic perspective on interspecific hybridizations in woody and herbaceous winter-hardy hibiscus and discuss breeding approaches to develop herbaceous winter-hardy hibiscus hybrids with novel flower colors and shapes resembling tropical hibiscus cultivars. By creating a broad genetic variability in herbaceous winter-hardy hibiscus hybrids we found a successful approach to increase the range of flower colors and shapes in these species and made them look very like their distant tropical relatives.

“…Variation in eyespot size in Hibiscus has been previously used to select new taxa, including the enlarged eyespot in H. syriacus 'Red Heart'. More recently, interspecific hybridization has been used to develop novel hybrids with large eyespots (Ha et al, 2010(Ha et al, , 2015. Studies on inheritance of ultraviolet patterns in Argentina anserina (Koski and Ashman, 2013) and Brassica rapa (Syafaruddin, 2006) suggest that eyespot size is a floral trait that may respond to selection.…”

Althea (Hibiscus syriacus) is an ornamental shrub prized for its winterhardiness, flower colors, and unique flower forms, including single-flowered and double-flowered types. Although floral traits are most important for breeders of althea, little is known about their segregation patterns. The objective of this study was to determine segregation patterns in flower color, including eyespot, among hybrid seedlings of elite taxa. Over 4 years, more than 3100 flowering seedlings were produced for observation of F1, F2, and backcross families. For each plant, data were collected including presence of eyespot and petal body color (CIEL*a*b*) using a colorimeter. Recessive testcrosses and χ2 analyses were performed among three taxa (‘Buddha Belly’, ‘Diana’, and White Chiffon®), and between this recessive group and a suite of colorful taxa. Self-pollination and intercrosses within homozygous dominant and homozygous recessive groups further confirmed their genotypes. Based on these results, we propose that eyespot is controlled by a single gene called spotless, named for the recessive allele that results in a complete elimination of color in flowers. Crosses that resulted in seedlings that all produced eyespots were observed to segregate for color in the petal body. Of these, one group produced white to blush pink petals, which was recessive to full color. Recessive testcrosses and χ2 analyses were performed among nine taxa exhibiting eyespots with white to blush petal bodies, and between taxa with full-color petal bodies. These testcrosses resulted in a putative homozygous dominant group composed mostly of blue and dark pink taxa, whereas the heterozygous group was composed mostly of pink taxa. Spotless taxa were also added to these two groups, suggesting an epistatic interaction with the spotless allele. Based on these results, we propose that petal body color is controlled by a single gene called geisha, named for the recessive allele that produces white to blush-pink petal bodies and dark red eyespot. This trait exhibits incomplete dominance and is under epistatic control by spotless. Geisha-type flowers lack pigment in the petal body, or exhibit a blush pink, likely produced by low levels of cyanidin, peonidin, and pelargonidin. The interaction and segregation of these two genes was confirmed in F1, F2, and backcross families from two crosses: Lil’ Kim™ × Blue Chiffon™ and Fiji™ × White Chiffon®. This study on segregation of flower color in H. syriacus contributes substantial and useful information on inheritance of color and will facilitate targeted breeding to improve this vibrant ornamental shrub.

“…Interspecific hybridization is an important breeding strategy that has been used for many ornamental crops (van Tuyl and Lim, 2003); in addition, it has been a common strategy for cultivar development of Hibiscus with novel phenotypes (Ha et al, 2014(Ha et al, , 2015Klips, 1999;Kuligowska et al, 2016;Pounders and Sakhanokho, 2016;van Huylenbroeck et al, 2000;van Laere et al, 2007). Several North American herbaceous perennial species of Hibiscus, including H. coccineus, H. laevis, and H. moscheutos, are reportedly compatible (Klips, 1999;Kuligowska et al, 2016).…”

“…Early research reported that interspecific hybridization between H. syriacus and the other two species could be accomplished only if H. syriacus was used as the female parent (van Laere et al, 2007); however, recent reports showed that this barrier is not impregnable. Daewangchun is a cultivar with a unique eyespot that was created and released using H. syriacus 'Samchully' as the female parent and H. sinosyriacus 'Seobong' as the male parent (Ha et al, 2015). Another new interspecific hybrid cultivar, Tohagol Red, resulted from the reciprocal cross combination (Ha et al, 2014).…”

“…Another new interspecific hybrid cultivar, Tohagol Red, resulted from the reciprocal cross combination (Ha et al, 2014). Both hybrid cultivars showed some advantages attributable to interspecific hybridization; however, crosses between H. sinosyriacus and H. syriacus do not appear to be a good strategy for creating infertile cultivars because Daewangchun and Tohagol Red are both fertile (Ha et al, 2014(Ha et al, , 2015. However, interspecific hybridization between H. syriacus (2n = 4x = 80) and H. paramutabilis (2n = 4x = 82) was viable only when H. syriacus was used as the female parent (van Laere et al, 2007;van Tuyl and Lim, 2003).…”

ADDITIONAL INDEX WORDS. hybrid sterility, wide hybrid, ornamental plant breeding, woody plant breeding ABSTRACT. Hibiscus syriacus is a woody shrub in the Malvaceae family that is common in landscapes due to its broad adaptability and variable ornamental characteristics. Interspecific hybridization has been used to improve Hibiscus by building novel floral traits, hybrid vigor, and hybrid infertility. A few interspecific hybrid Hibiscus cultivars (H. syriacus · H. paramutabilis), such as Lohengrin and Resi, are notable because of their vigorous vegetative growth, female infertility, and large flowers. However, little is known about the male fertility and breeding potential of these hybrid cultivars, which could increase flower size by backcrossing to H. syriacus. In this study, we estimated male fertility of the two hybrid cultivars by acetocarmine staining and in vivo pollination and assessed selection methods for floral traits, specifically flower size and petal number. A BC 1 F 1 population of 294 individuals was developed by crossing hybrid cultivars Lohengrin or Resi with a variety of double-flowered H. syriacus cultivars. A negative correlation between petal number and petal area was detected by quantile regression, which is a method that circumvents the problem of simple linear regression, which violates statistical assumptions. Quantile regression was used to build simultaneous selection thresholds for different levels of required stringency. As expected, the female fertility of hybrid cultivars was extremely low or zero; however, the male fertility of hybrid cultivars was not reduced compared with H. syriacus cultivars. A negative linear correlation between the petal number and petal area of the BC 1 F 1 individuals was observed. In addition, quantile regression was recommended to set a single selection threshold to be applied to the selection of two negatively correlated traits, which was more effective than independent selection of petal numbers and petal areas among progeny.
