Article Info ABSTRACT Date of Acceptance: 22 June 2018 In this article was presented the results of seed samples and about 200 herbarium specimens of 17 vetch species collected on 36 routes from different regions of Azerbaijan in 2015-2017, distribution based on their descriptive data, evaluation based on morphological and ecological indicators. In the study, first main cluster is divided to 12 groups: V. tenuifolia subsp. variabilis (Z02, Z7, E8), which belongs to subgenus Cracca (according to Radghi, Fedchenko); V. narbonensis (K20)- which belongs to section Faba, V. villosa (Z3), V. sativa subsp. sativa (Q2, K14, A1-1) - to section Vicia, V. lutea (C4, K18), V. pannonica (Z4) – to section Hypechusa and V. abbreviata (Z11)- to section Atossa (according to Kupicha) and the fourth main cluster which is related to 10 samples. Date of Publication: 06 July 2018 Keywords Cluster analysis DIVA-GIS Ecological indicators Vetch species Introduction Vetch (Vicia L.) is one of the most widely spread genera of the Fabaceae Lindl. of the class Magnoliopsida. The species included into the genus are spread across the northern hemisphere, including the middle mountain ranges in Azerbaijan. The species of genus are precious fodder plants. It contains many proteins. Dry and green mass is best used by animals (Brainard, et al. 2012). Vicia was first described by K. Linney (Linneaus, 1753). In the world flora, there are 200 species of vetch (Vicia L.) (Tsvelyov, 1987) and 41-43 species of vetch in Azerbaijan (Asgarov, 2011). Although different classical botanists in the Caucasus expressed interesting ideas about the genus Vicia L., its classification, and the types in Azerbaijan, B. Fedchenko gave the first comprehensive system of this genus “in the USSR Flora”. He divided this genus into 3 subgenera, 4 sections, 31 rows. Forty one species of vetch of Azerbaijan are grouped into 3 subgenera, 20 rows (Fedchenko, 1948). Although Grossheim described the genus of the "Caucasian flora" (1952), he adopted the system of Fedchenko. He noted that that there are 150 species K. V. Asadova and A. M. Asgarov (2018) / Distribution and Ecobiological Research of Vetch (Vicia L.) Species in Azerbaijan 27 Int. J. Curr. Res. Biosci. Plant Biol. (2018) 5(7), 27-36 of vetch in the world, 48 wild species and one cultivar in Caucasus (Grossheim, 1952). In 1970, Dagestani botanist A. D. Radghi published the Caucasian species of Vicia L. genus. In own proposed system, Radghi adopted a large number of subsections and series (Seriaes) within the sections, using the division of the genus into the sub-genera. She has shown the spread in total 36 species of this genus and has grouped them into 3 subgenera, 8 section, 19 subsection and 12 series (Radghi, 1971). 28 wild and 1 cultivated species of Azerbaijan were divided into 3 subgenera, 8 sections, 16 subsection and 11series in this system. In the 80's, the Petersburq botanic Tsvelyov developed the system of Vicia genus spreading in eastern Europe. Here, too, the division of genera into subgenera is accepted. The Caucasus, including Azerbaijan, is also reflected in this system. He has divided the Vicia genus into 3 subgenera (Cracca, Ervum and Vicia) and sections (Oroboidea, Cracca, Lenticula, Ervum, Ervilia, Sepium, Hypechusa, Vicia, Lathyroides, Pseudolathyrus and Faba), has given series of Radji within the subseries and has described several new sections (Oroboidea, Lenticula, Ervilia, Hypechusa, Lathyroides and Pseudolathyrus). In 1987, Tsvelyov improved the system of Vicia, which he proposed earlier in the "Flora of the European part of USSR" (Tsvelyov, 1987). Systematic of the Vicia L. genus of Turkish flora were studied by P. Davis and U. Plitman (Davis, Plitmann, 1970). In this system vetch species has been distributed in 3 groups. Turkish species has been grouped into 58 wild and 1 cultural species in 3 groups, Azerbaijanian species has been grouped into 26 wild and 1 cultural species in 3 groups. The only taxonomic study on the whole genus was conducted by F. K. Kupicha at the world level (Kupicha, 1973, 1975, 1976). Kupicha (1979) referred to this genus of Vicieae tribe in "The taxonomic studies in the tribe Vicieae (Leguminosae)" and gave information about 11 sections of genus. Although in the multivolume "Flora of Azerbaijan" have been described 41 wild species, 1 cultivar, in "The plant world of Azerbaijan" of A. Asgarov it has been given the information on 43 wild species of and 1 cultivar (Asgarov, 2016), the varietal systematics of genus and the biomorphological diversity have not been widely studied. Vetch (Vicia L.) is one of the highest quality, two and perennial fodder grass. Morphological signs are important in systematic of vetch species, as well as in the design of the prescribed keys. The main characteristic of the genus is the too the column, correlation of crown and calyx lobe, and the leaf finish with clasper. The calyx tube is usually curved from the base. The vexillum is hollow or full. The wing petals are joined to slipcover. The column is thoroughly hirsute or unilateral bearded on the top, rarely naked. Species are distinguished by the color of the crown, the shape of the flower, the characteristics of the leaf and stipule, the fruit sand seeds. The leaves are pair featherlike, ends with many or less branched beads, or with a sharp end, sometimes with a single leaf. Stipules are often semi-gothic shaped. The flowers are 1 or 2-3, locate in the axillary bud, almost as a sessile or cluster is multi flowered. The peduncle is longer than the leaves, or equal to it, and sometimes is shorter. The corolla is yellow, red, purple, blue, blue, matte or dark purple, red-purple, blue, yellowish-orange, bright purple, pale blue, bright blue and so on in colors. Calyx is 5 toothed, usually it has 3 upper are longer than 2 down teeth. The corolla resembles is a common butterfly structure. 9 adjacent stamens form a pipe, and 1stamen is free. The vexillum is undescribed claw, the wings are almost equal to the claw, slipcover is blunt, shorter than the vexillum, sometimes with the same length. The stem is gentle or sloppy, externally tight or sparse, sometimes almost naked, flat shield or creeping. Legume is on short or long stalk; Legume is too or less squeezed; it is hirsute or sliced; cylindrical, bead shaped. Usually it is multi-seeded, and sometimes it is twoseeded. Legume is soft, fluffy, or bare. Cytological studies show that the genus has a chromosome set of 2 n = 10, 12, 14, 16, 18, 28 (Davis and Plitmann, 1970; Kupicha, 1973; Tsvelyov, 1987). K. V. Asadova and A. M. Asgarov (2018) / Distribution and Ecobiological Research of Vetch (Vicia L.) Species in Azerbaijan 28 Int. J. Curr. Res. Biosci. Plant Biol. (2018) 5(7), 27-36 Materials and methods In 2015-2017, in the Department of Ecobotanics and Systematics of the Institute of Genetic Resources, under the guidance of A. Asgarov at the expeditions on 36 routes from different regions of Azerbaijan 17 species (about 200 herbarium specimens) and seeds were collected and studied. Moreover, collections of the Herbarium Funds of the Institute of Botany of ANAS, the Genetic Resources Institute (AGRI) and the Institute of Botany of the Republic of Georgia (TBI) were studied as a research material. The literature and Internet data have been analyzed. The definition of the nomenclature issues is based on The International Botanical Code (Austria, Vienna, 2005; Allkin et al., 1986) In the determination of species and identification of their nomenclature were used “Flora of Azerbaijan” and A. Asgarov's books (Asgarov, 2011 and 2016), in the analysis of other features were used Ch. Raunkier (Raunkiaer, 1937) and I. Serebryakov's classification (Serebryakov, 1964). Comparative morphological (Gunn and Kluve, 1969, 1970 and 1976) floristic (Tupikova, 1926), biomorphological, sistematic (Maxted, 1990 and 1995) phytocenological and experimental methods (Leht, 2005) were used in the research. Range maps of the collected species were compiled using DIVA-GIS computer program. The amount of annual rainfall, temperature information is based on the PAST program. Results and discussion The distribution of the vetch species is based on five major botanical-geographical regions of Azerbaijan: 1. Greater Caucasus, 2. Lesser Caucasus, 3. Kura-Araks, 4. Talysh region and 5. Nakhchivan. Distribution of Vicia L. species in botanical-geographical regions of Azerbaijan is given in Table 1. Table 1.

(2018) 5(7), 27-36 been determined by the fact that on min rainfall was collected for V. peregrina, V. sativa subsp. nigra, V. tetrasperma from territory of Kurdamir region, Karrar village (360 mm), on the maximum rainfall V. lutea and V. narbonensis were collected from territory of Masally region, Kalinovka village (701 mm). Min temperature for January was encountered in territory of Oguz region, Dashagil village (17.4°C), max temperature in territory of Geokchay region, Bighyr village, (33.2°C). Min average annual temperature was observed in territory of Oguz region, Dashagil village (-7.5°C), max average annual temperature in territory of Mingachevir city, the 7th km of road Chaldan (20.5°C). Based on the results, by using the Cluster Analysis method was carried out a taximetric analysis. The analyzes were conducted through the SPSS Win (SPSS 16.0) program. The phenomenon (taximetric) relationship between Vicia L. species is shown in Fig. 3. As can be seen from the Table, 4 main clusters were observed at the 12 level. The first main cluster is divided to 12 groups: V. tenuifolia subsp. variabilis (Z02, Z7, E8), which belongs to subgenus Cracca (according to Radghi, Fedchenko); V. narbonensis (K20)- which belongs to section Faba, V. villosa (Z3), V. sativa subsp. sativa (Q2, K14, A1-1) - to section Vicia, V. lutea (C4, K18), V. pannonica (Z4) – to section Hypechusa and V. abbreviata (Z11)- to section Atossa (according to Kupicha). The second cluster is related to 4 samples: V. monantha subsp. monantha (A1, A1-2, K9), V. nissoliana (E1-2), which belongs to section Cracca (according to Radghi, Kupicha). The third main cluster is composed of 4 samples: V. tetrasperma (L1, M2, E6), which belongs to section Ervum, V. elegans (E1-1) - to section Cracca (according to Radghi, Kupicha). Fig. 2: Average annual rainfall and temperature of collected samples. - The red square is the maximum temperature indicator (Tmax); - The blue square is the minimum temperature indicator (Tmin); - Monthly precipitation (mm); In 2015-2017, 17 species were selected for phenethical (taximetric) analysis of vetch species during the 36 expedition researches. At least two samples were studied from each population and each population was marked as Operational Taxonomic Unit (OTU). For the biomorphological analysis, 33 quantitative and qualitative characteristics were selected. At least 2-3 sample parameters taken from each population were measured and the average score was calculated. Finally, the fourth main cluster is related to 10 samples: V. peregrina (Q3, B2, Z9), which belongs to section Peregrinae, V. sativa subsp. nigra (LZ, D6, K2) - to section Vicia, V. bithynica (M5) - to section Faba (Kupicha). V. sativa subsp. cordata (A16), V. grandiflora (E4), which belongs to section Vicia and V. hirsuta (V2) - to section Cracca (according to Kupicha). The species studied belong to morphological and ecological groups. Some samples of the first cluster are mesophytes and annual plants-V. narbonensis (K20); V. villosa (Z3); V. sativa subsp. sativa (Q2, K14, A1-1); V. lutea (C4, K18), V. pannonica (Z4), and others are mesoxerophytes and perennial plants-V. abbreviata (Z11), V. tenuifolia subsp. variabilis (Z02, Z7, E8) (Serebryakov, 1964). Some samples of the second cluster are xerophytes and annual plants-V. monantha subsp. monantha (A1, A1-2, K9), but other is mesoxerophyte and perennial plant- V. nissoliana (E1-2). K. V.
