“…L. straminea was considered a descendant of Lycoris chinensis and Lycoris radiata var. pumila [ 1 , 26 , 27 ]. L. straminea (2n = 19) and L. hunanensis (2n = 18) were of similar species based on morphological features such as leaf shape and flower colour etc.…”

Background Hybridization is considered as an important model of speciation, but the evolutionary process of natural hybridization is still poorly characterized in Lycoris. To reveal the phylogenetic relationship of two new putative natural hybrids in Lycoris, morphological, karyotypic and chloroplast genomic data of four Lycoris species were analyzed in this study. Results Two putative natural hybrids (2n = 18 = 4 m + 5t + 6st + 3 T) possessed obvious heterozygosity features of L. radiata (2n = 22 = 10t + 12st) and L. aurea (2n = 14 = 8 m + 6 T) in morphology (e.g. leaf shape and flower color), karyotype (e.g. chromosome numbers, CPD/DAPI bands, 45S rDNA-FISH signals etc.) and chloroplast genomes. Among four Lycoris species, the composition and structure features of chloroplast genomes between L. radiata and the putative natural hybrid 1 (L. hunanensis), while L. aurea and the hybrid 2, were completely the same or highly similar, respectively. However, the features of the cp genomes between L. radiata and the hybrid 2, while L. aurea and the hybrid 1, including IR-LSC/SSC boundaries, SSRs, SNPs, and SNVs etc., were significantly different, respectively. Combining the karyotypes and cp genomes analysis, we affirmed that the natural hybrid 1 originated from the natural hybridization of L. radiata (♀) × L. aurea (♂), while the natural hybrid 2 from the hybridization of L. radiata (♂) × L. aurea (♀). Conclusion The strong evidences for natural hybridization between L. radiata (2n = 22) and L. aurea (2n = 14) were found based on morphological, karyotypic and chloroplast genomic data. Their reciprocal hybridization gave rise to two new taxa (2n = 18) of Lycoris. This study revealed the origin of two new species of Lycoris and strongly supported the role of natural hybridization that facilitated lineage diversification in this genus.

“…In the breeding work of Lycoris, we are committed to breeding new and superior strains with high ornamental value, including novel colors, various flower shapes, and novel fragrances. For example, we previously published the new cultivars Yi Xian Chun Tao (Zhang et al 2022) and E Huang Xiao Ran (Wang et al 2023), which were excellent individuals selected from the natural populations of L. longituba and L. straminea, respectively. In this study, we observed an individual and several clones that have different flower traits compared with L. longituba.…”

“…Compared with sexual reproduction by seeds, asexual reproduction not only facilitates the preservation of stable ornamental traits but also shortens the development time of small bulbs, leading to earlier flowering (Ramawat and Merillon 2013). Cutting bulbs and plant tissue culture are the main methods for the asexual reproduction of Lycoris (Qing et al 2007;Wang et al 2023). In bulb cutting, it is necessary to choose a suitable season.…”
