Abstract. Allium ampeloprasum (Amaryllidaceae) is recorded as a new taxon for the flora of Iran. It is morphologically
most similar to Allium atroviolaceum and Allium iranicum. This species is compared with its two aforementioned relative
species and some notes are given on its affinities. A full description, images and a distribution map are also...

One of the largest monocotyledonous genus in the Amaryllidaceae family is the Allium genus that includes approximately 900 species. This study aimed to examine the variations and clustering of eight Iranian endemic Allium species based on karyotype features. The species were collected from wild habitats across different geographical areas of Iran....

... During the last two decades Allium species occurring in Iran were a main target of taxonomic research activities resulting in a large number of anatomical (Khorasani et al. 2018a), morphological (Khorasani et al. 2018b), molecular (Veiskarami et al. 2019), and karyological (Dolatyari et al. 2018) contributions (only a few most recent publications were cited). Also, more than 50 species and subspecies were newly described or reported from Iranian territory (Govaerts et al. 2022). ...
Meiosis in pollen mother cells (PMCs) was studied of 23 Iranian Allium species (33 accessions, 105 individuals) that belong to two subgenera and six sections. Materials of 13 species were sampled from (near) type locations. Gametic chromosome numbers, chromosome configurations at metaphase I, chiasma frequency, as well as type and percentages of abnormalities were recognized. The basic chromosome number for all taxa investigated was x = 8. Most taxa were diploid and showed eight bivalents or in rare cases two or four pairs of univalents, but in A. subakaka, A. ubipetrense and A. zagricum tetravalents also occurred. Meiosis in less than 10% of PMCs of diploid accessions was disturbed displaying lagging chromosomes, chromatid bridges, micronuclei, or unbalanced chromosome segregations, but very rarely more than one kind of irregularities were found within one dividing cell. One to three B chromosomes were found in 11 accessions, and were recognized for the first time in A. alamutense, A. elburzense and A. iranshahrii. Our data showed no correlation between the occurrence of B chromosomes and the chiasma frequency, and also no noticeable effect of habitat factors on meiotic chromosome behaviour. The studied accessions of A. atroviolaceum and A. sabalense were tetraploid (n = 16) showing irregular meiosis in 20 - 69% of the PMCs which is regarded as sign of autopolyploidy. Since only two out of 31 investigated accessions belonging to subg. Melanocrommyum were tetraploid, we may suggest a trivial role of polyploidy in the evolution of this subgenus.
The article presents the results of studies of biological and morphological features of introduced forms of Elephant garlic (Allium ampeloprasum var. ampeloprasum L.) in comparison with garlic cultivars (Allium sativum L.) Sofiivskyi and Prometei. Research on collection samples began in 2016. Samples of Elephant garlic were obtained by expeditionary method (from Greece and Khmelnytsky region). Several plants with long dark green, broad and leathery leaves, pink inflorescences with microcloves (bulbils), large bulbs were selected and vegetatively (clonally) propagated to create a population of homogeneous plants. The study used field, laboratory, statistical, computational and analytical methods. The research was conducted in the training and production department of Uman National University of Horticulture during 2020-2021, using collection varieties of different ecological and geographical origin (Ukraine and Greece). Cultivars/varieties were evaluated according to the following parameters: plant height, leaf area, and indicators of individual productivity (bulb weight, number of teeth and bulbils, etc.), yield and nutritional value. It was found that varieties of Аllium ampeloprasum var. ampeloprasum L. react more sharply to changes in growing conditions than cultivars of Allium sativum L. Winter hardiness of cultivars of Elephant garlic was in the range of 98,0–100%, but they had low adaptability, where the coefficient of adaptability (CA) was 0,45–0,49, and in winter garlic CA = 0,95–0,97. Plants of Аllium ampeloprasum var. ampeloprasum L. do not form air bubbles, but on the bottom and under the covering scales of the bulb is formed from 3-5 to 10 pcs. bulbils. Varieties № 2 and № 3 have 7.1 and 5.1 large teeth in their structure, respectively. The weight of the bulb without removal of the flowering scape in the cultivar Sofiivskyi was less than the samples № 2 and № 3, respectively, by 28.4-53.3 g. With the removal of the flowering scape, the difference increased to 60.5-68.6 g. Yield of Аllium ampeloprasum var. ampeloprasum L. without removal of the flowering scape № 2 was lower than the standard by 1.7 t/ha, at the same time the variety № 3 exceeded the standard by 1.1 t/ha. With the removal of the flowering scape, the yield of cultivars № 2 and № 3 exceeded the cultivar Sofiivskyi by 1.6 and 2.2 t/ha. As a result of research it was found that the introduced forms of Аllium ampeloprasum var. ampeloprasum L. have high indicators of economic value, but they are limited in the first years of cultivation, the period of adaptation to new soil and climatic conditions, which creates some difficulties in their cultivation and reproduction.
