“…While tulip may be an appropriate Fritillaria-type for comparison, only few works on tulip hybridization have been reported (Van Eijk et al 1991;Van Creij et al 1997, and even fewer on tulip 3x 9 2x/ 4x crosses (Mizuochi et al 2009). Mizuochi et al did observe, however, that the ratio of embryo and endosperm ploidy level of 2x 9 2x or 3x 9 2x in tulip is invariably 1:1.…”

Lilium are Fritillaria-type plants. Triploid lilies, regardless of their male sterility, can be used as female parents to cross with appropriate males, in contrast to other triploid Polygonum-type plants, which are usually seedless. Up to now, however, little attention has been paid to the reason. Here we made allotriploid 9 diploid/tetraploid crosses in Lilium. Endosperm and progenies of LAA 9 AA/AAAA crosses were analyzed for ploidy level and genome composition. The endosperm of some LAA 9 AA/ AAAA ovules developed well but there was little or no development of LAA 9 LL/OO endosperm. The endosperm genome composition of LAA 9 AA, LAA 9 AAAA, LAA 9 LL, LAA 9 OO are theoretically derived as 5A ? 2L, 6A ? 2L, 4A ? 3L, 4A ? 2L ? O, respectively. Genomic in situ hybridization showed that the progenies of LAA 9 AA/ AAAA were aneuploid. Based on the experimental results and analyses, our hypothesis is that five same genomes of endosperms are essential for its development in triploid 9 diploid/tetraploid crosses of Lilium. The hypothesis can explain the success or failure of 3x 9 2x/4x crosses in Lilium and is of importance for lily breeders who need to know the likelihood of success when producing new cultivars of this economically important horticultural crop.

“…Many attempts have been made to combine the desirable traits in stone fruits by interspecific hybridization; however, barriers such as pre-fertilization incompatibility and post-fertilization sterility (Rubio-Cabietas and Socias 1996;Van Creij et al 1997;Boavida et al 2001;Guillaumin et al 2003) have limited its success. Methods to control or overcome the pre-fertilization barriers include choosing more suitable parents for hybridization, pollination at the balloon stage of the flower buds, and pollen treatment (Ryzhkov and Ostapenko 1974;Suzuki et al 1988;Valk et al 1991).…”

Embryo rescue technique was used successfully to produce interspecific hybrids by crossing peach (P. persica) as a female parent with apricot (P. armeniaca) and plum (P. salicica). In those crosses that had 'Yuhualu' or 'Zhonghuashoutao' as female parents, hybrid embryos aborted from the 7th or 8th week after pollination mainly due to post-pollination incompatibility. An embryo rescue protocol was established to rescue such embryos and recover hybrid plants. Modified half-strength MS medium containing 4 mg l -1 6-BA and 0.5 mg l -1 IBA produced up to 90% germination in the embryos. Modified MS medium with 1.0 mg l -1 6-BA and 1.0 mg l -1 IBA gave the highest bud induction and multiplication whereas modified MS medium containing 0.5 mg l -1 IAA and 0.2 mg l -1 NAA gave the best rooting percentage. All the hybrids obtained using this embryo rescue technique were verified using simple sequence repeat (SSR) markers. A series of pollen treatments were carried out to partially overcome pre-pollination incompatibility, and it was found accidentally that pollen treatment with electrostatic field not only improved pollen germination but also increased the multiplication coefficient of embryo-induced shoots.

“…Their horticultural popularity, especially in Europe during the mid-seventeenth Century, led to bulbs being infamously traded in Holland as a form of speculative currency during a period that came to be known by historians as “tulip mania.” Although, there has been considerable research into the biology of tulips native to the Middle East and North Africa (Eijk et al, 1991; van Tunen et al, 1993; Van Creij et al, 1997; van Rossum et al, 1998; Zonneveld, 2009), much less is known of the East Asian tulips (e.g., Tulipa edulis ), a group of species that most botanists today recognize as a distinct genus Amana Honda (Liliaceae). Amana is comprised of ca.…”

The genus Amana Honda (Liliaceae), when it is treated as separate from Tulipa, comprises six perennial herbaceous species that are restricted to China, Japan and the Korean Peninsula. Although all six Amana species have important medicinal and horticultural uses, studies focused on species identification and molecular phylogenetics are few. Here we report the nucleotide sequences of six complete Amana chloroplast (cp) genomes. The cp genomes of Amana range from 150,613 bp to 151,136 bp in length, all including a pair of inverted repeats (25,629–25,859 bp) separated by the large single-copy (81,482–82,218 bp) and small single-copy (17,366–17,465 bp) regions. Each cp genome equivalently contains 112 unique genes consisting of 30 transfer RNA genes, four ribosomal RNA genes, and 78 protein coding genes. Gene content, gene order, AT content, and IR/SC boundary structure are nearly identical among all Amana cp genomes. However, the relative contraction and expansion of the IR/SC borders among the six Amana cp genomes results in length variation among them. Simple sequence repeat (SSR) analyses of these Amana cp genomes indicate that the richest SSRs are A/T mononucleotides. The number of repeats among the six Amana species varies from 54 (A. anhuiensis) to 69 (Amana kuocangshanica) with palindromic (28–35) and forward repeats (23–30) as the most common types. Phylogenomic analyses based on these complete cp genomes and 74 common protein-coding genes strongly support the monophyly of the genus, and a sister relationship between Amana and Erythronium, rather than a shared common ancestor with Tulipa. Nine DNA markers (rps15–ycf1, accD–psaI, petA–psbJ, rpl32–trnL, atpH–atpI, petD–rpoA, trnS–trnG, psbM–trnD, and ycf4–cemA) with number of variable sites greater than 0.9% were identified, and these may be useful for future population genetic and phylogeographic studies of Amana species.
