“…However, 'Baiyun', 'Longhua', and 'Jincuilei' have different karyotypes. The three cultivars were mutants of L. macranthoides; they produce large flowers, but the flowers never open and contain high chlorogenic acid (CGA) content (Chen et al, 2013;Wang et al, 2009Wang et al, , 2013. The karyotype of L. japonica 'Jinfeng 1' is closely similar to that of L. japonica 'Sijijinyinhua' listed in Table 1, but the latter has four satellite chromosomes.…”

“…Because of the lack of fundamental genetic information, such as chromosome numbers, karyotypes, and DNA contents, there has been no documented breeding scheme for genetic improvement of Lonicera species. The current effort has been primarily limited to the selection of sports or induced mutations (Chen et al, 2013;Wang et al, 2013;Zeng et al, 2017). The present study investigated some important cultivars of Lonicera species and documented their ploidy levels, karyotypes, and DNA contents, which could be potentially valuable for improving breeding efficiency of Lonicera species.…”

“…Moreover, ploidy levels and genome sizes are important in crop improvement (Bennett, 1998). Because of the lack of reliable chromosome and genomic information, current breeding on Lonicera has been primarily focused on the selection of naturally occurring mutations (Chen et al, 2013;Wang et al, 2013;Zeng et al, 2017).…”

Ploidy levels and genome sizes have significant implications in plant evolution and crop improvement. Species of Lonicera L. have long been cultivated as medicinal, ornamental crops, or both. However, chromosome numbers, karyotypes, and DNA contents have only been documented in a few species, of which some controversies regarding basic chromosome numbers and karyotypes remain. This study analyzed the chromosome numbers and karyomorphology of 11 cultivars across four species and also the DNA content of 10 cultivars representing six species of Lonicera. Among them, the chromosome numbers of nine cultivars are reported for the first time. Results showed that the basic chromosome number of x = 9 was constant, and chromosome numbers of 2n = 18, 27, 36, or 54 were observed, suggesting that polyploidy exists in the genus. Five cultivars are diploid with 2n = 18; one cultivar is triploid, four are tetraploid, and one is hexaploid. The karyotypes of all studied cultivars are 3B or 3A, except Lonicera sempervirens ‘Crimson Cascade’ that is 2B based on the Stebbins’ asymmetry classification of karyotypes. The asymmetry index (A1) values vary from 0.47 to 0.60. The chromosome lengths range from 0.77 to 4.09 μm. Total karyotype lengths differ from 33.55 to 78.71 μm. The 1C-value of 10 cultivars varies 3-fold, ranging from 1.158 to 3.664 pg. Information gathered from this study could be valuable for improving breeding efficiency in the development of new cultivars of Lonicera with enhanced medicinal, ornamental value, or both.

“…Similar to 'Fenglei', flowers of two mutants 'Longhua' (Chen et al, 2013) and 'Huayao-Wanshou' (Wang et al, 2013) selected from L. macranthoides also do not open, and their CGA contents were also significantly greater than their progenitor. Possibly, nonopening flowers may be a characteristic associated with high CGA content in Lonicera species.…”

“…The current focus has been primarily on L. japonica and L. macranthoides. Wang et al (2004Wang et al ( , 2009a isolated three naturally occurring mutants: 'Jincuilei', 'Yincuilei', and 'Baiyun' from L. macranthoides in Hunan province, China, and later 'Longhua' (Chen et al, 2013) and 'Huayao-Wanshou' (Wang et al, 2013) were selected from L. macranthoides. This article reports a new cultivar Fenglei, a selection from L. japonica.…”
