“…(Wang and Tang, 1978). Allium de Itoide -fis tub sum which was described by Yu et al (1981) (Baldwin, 1992;Baldwin et al, 1995), but ITS 1 in Poaceae is longer than ITS 2 (Baldwin et al, 1995). ITS 2 in the taxa examined in this study is longer than ITS 1, except for A. tuberosum and A. ramosum of section Butomissa in subgenus Rhizirideum.…”

“…2). Allium anisopodium that was described at Bisundae of ML Sorak by Yu et al (1981) was considered as A. cyaneum var. deltoides, because the morphological characters were different from the taxonomic descriptions (Vvedensky, 1944;Wang and Tang, 1978) and it was grouped with A. cyaneum var.…”

“…Lee (1996) summerized Korean Allium as 17 species, three varities, and two formas including cultivars. Yu et al (1981) studied the taxonomy of the Korean Allium, and reported 12 species, two varieties, and one forma.Many morphological or anatomical studies on Allium have been performed, but taxonomic studies based on flower, pollen, leaf, and seed did not reveal the gross morphological derivative characters among the genera, subgenera, and sections, due to the difficulty in identification of the minute characters of the dried specimen (Mes et al, 1997). Recently, molecular approaches such as isozyme, chloroplast DNA, and ITS sequence of nuclear rDNA have been applied to solve the morphological problems (Berg et al, 1996;Dubouzet et al, 1997;Mes et al, 1997;Dubouzet and Shinoda, 1998;Klaas, 1998).…”

Phylogenetic relationships among the Korean taxa of the genus Allium subgenus Rhizirideum and some related taxa were assessed on the basis of ITS sequences of nuclear ribosomal DNA. Twenty-eight accessions of the genus Allium L. consisting of subgenera Rhizirideum (19 taxa), Allium (5 taxa) and Amerallium (one taxon) were analyzed. The variation in the ITS region was informative at the levels of section except for sect. Reticulato-bulbosa which is known to be of multiple origin. The ITS 2 region was longer than the ITS 1 region, and all of the investigated Allium taxa were the same in length in the 5.8S region except for A. monanthum. Allium cyaneum var. cyaneum was the shortest (635 bp) and A. victorialis the longest (646 bp) among the investigated Korean taxa. The three morphologically similar taxa, A. thunbergii, A. sacculiferum that has been included in A. thunbergii, and A. deltoide-Jistulosum, had the same ITS lengths of 641 bp, but were clearly distinguished in the phylogenetic analysis of their ITS sequences.Allium L. (Alliaceae) contains about 700-750 taxa in northern temperate region, including a number of important edible plants such as onion, green onion, garlic, leek and wild garlic (Hanek et al., 1992;Berg et al. 1996;Mes et al., 1997;Klaas, 1998). The genus is characterized by perennials with alliaceous ordour and tunicated bulb. Leaves are basal, but their bases may form a flat or terete, sometimes fistular pseudostem. Inflorescences are umbel-like with few or many flowers, sometimes with bulbils. Tepals are six, and usually small, free or slightly united below. Stamens are six, and usually attached to the base of tepals. Filaments are often dilated at the base. Ovules are 1-10 in each locule, but often two. Seeds are broad and triangular in transection, with a thick phytomelan crust (Rahn, 1998).The classification at intrageneric levels based on the morphological characters has been in dispute (Vvedensky, 1944;Bentham and Hooker, 1965;Hanelt et al., 1992). Recently, the genus was classified into five subgenera (Allium, Amemllium, Rhizirideum, Melanocrommyum, Caloscordon) according to the chromosome number and chloroplast DNA polymorphism (Samoylov et al., 1999).Most of the Korean Allium except for A. monanthum, wild garlic and green onion belong to the subgenus Rhizirideum (G. Don ex Koch) Wendelbo having a rhizome *Tel: 82-2-3277-2366, Fax: 82-2-3277-2385 and basic chromosome number of 8 (Dubouzet et al., 1997;Klaas, 1998). Since Palibin (1901) had reported A. japonicum, Park (1949) recorded 21 species and two varieties including five cultivars, and Nakai (1952) summerized that there are 20 species, one variety and one forma in Korean Allium. Chung (1956Chung ( , 1965 illustrated 11 species, and Kitagawa (1979) recorded 13 species, one variety, and one forma in Korean Allium. Lee (1996) summerized Korean Allium as 17 species, three varities, and two formas including cultivars. Yu et al. (1981) studied the taxonomy of the Korean Allium, and reported 12 species, two varieties, and one forma.Ma...

“…minor (2n = 16), a wild species reported only from South Korea (Yu et al 1981), has a long flowering period, winter hardiness, and bacterial and fungal resistance. Since this species might have potential in broadening the narrow genetic basis of cultivated onion crops, experiments were carried out to evaluate the regenerative response of this plant in vitro.…”

Callus regeneration was observed from flower buds of Allium senescens var. minor inoculated in BDS, MS or B5 medium supplemented with 4.4 IxM benzyladenine alone or in combination with 4.5 ~M 2,4-dichlorophenoxy-acetic acid (2,4-0), with 2,4-0 and kinetin (4.5 p,M/4.6 ~M) or with 5.3~M naphthaleneacetic acid. Ovules enlarged initially but the embryogenic tissue degenerated as callus development progressed from the nectar regions of the petals. Shoot buds and leaf primordia developed from the meristematic protuberances that originated from the surface of the callus. BDS medium with 4.5 ixM 2,4-0 and 13.3 IxM BA was most suitable for shoot multiplication. The regenerated shoots were rooted in respective liquid medium without any growth regulators and successfully transferred to soil with 90% survival rate.Abbreviations: BA -N6-benzyladenine, 2,4-D -2,4-dichlorophenoxyacetic acid, NAA -a-naphthaleneacetic acid Allium senescens var. minor (2n = 16), a wild species reported only from South Korea (Yu et al. 1981), has a long flowering period, winter hardiness, and bacterial and fungal resistance. Since this species might have potential in broadening the narrow genetic basis of cultivated onion crops, experiments were carried out to evaluate the regenerative response of this plant in vitro. We report here callus and plantlet regeneration from flower buds of A. senescens var. minor.Flower heads, collected at the time of meiosis in the anthers of the largest flower buds, were disinfested for 1 min in 70% ethanol and 10 min in 5% sodium hypochlorite solution followed by four washes in sterile double-distilled water. Individual flower buds with 2-3mm long pedicels were removed aseptically from the closed spathe; older and younger buds were discarded. Ten to fifteen flower buds of approximately 1 mm in diameter were selected from a single umbel for inoculation. Five to seven flower buds were placed in each 50 ml metalcapped Erlenmeyer flask containing 20ml of medium.

A new species, Allium pseudosenescens, belonging to sect. Rhizirideum (Alliaceae), is described from northeastern China. It is easily distinguished from A. senescens by the slender pedicels, pale pink perianths, narrower tepals and ovaries, yellowish anthers, and sometimes toothed subulate filaments. Also, A. senescens var. minus in sect. Rhizirideum is raised to the rank of species, as A. minus. This Korean endemic taxon is shown to be a biologically distinct species based on morphological and cytological characters. Taxonomic keys for the species of Allium sect. Rhizirideum in northeastern China and Korea are provided.
