Four zones according to altitude including 20 villages and especially surrounding forests were visited. Data on uses and ethnobotany was collected through interviews that were one-on-one with respondents carefully selected to represent both male and female. Additionally a general survey of the area including other places of Savadkouh has been performed. The fruit trees and shrubs include Berberis sp., Crataegus sp., Cydonia oblonga, Diospyros lotus, Ficus carica, Malus orientalis, Mespilus germanica, Prunus cerasifera ssp. macrocarpa, Prunus spinosa, Punica granatum, and Rubus sp. Most of these are gathered from the wild, or occasionally cultivated in homegardens. The results of this study show that all of these species are used as sources of local foods and medicines. The area should be considered as an important evolutionary centre for fruit trees and shrubs and should be taken into serious consideration for discussions about fruit tree and shrub evolution. Germplasm collection activities, in situ conservation programs and interdisciplinary analysis of socioeconomic aspects of rural communications will be necessary in future studies.

Determined genetic relationship between the species or genera is very valuable for genetic improvement studies. The chloroplast matK gene sequences ranging from 730 to 1545 nucleotides were downloaded from the GenBank database. These DNA sequences were aligned using Clustal W program. We employed the maximum parsimony method for phylogenetic reconstruction using PAUP* program. Trees resulting from the parsimony analyses were similar to those generated earlier using single or multiple gene analyses, but our analyses resulted in strict consensus tree providing much better resolution of relationships among major clades. We found that gymnosperms (Pinus thunbergii, Pinus attenuata and Ginko biloba) were different from the monocotyledons and dicotyledons. We showed that Cynodon dactylon, Panicum capilare, Zea mays and Saccharum officiarum (all are in the C4 metabolism) were improved from a common ancestors while the other cereals Triticum Avena, Hordeum, Oryza and Phalaris were evolved from another or similar ancestors.

The USDA-ARS National Plant Germplasm System Malus collection is maintained by the Plant Genetic Resources Unit (PGRU) in Geneva, NY. In the 1990s, a core subset of 258 trees was hand-selected to be representative of the grafted Malus collection. We used a combination of genotypic and phenotypic data to compare the diversity of the 198 diploid trees in the original core subset with that of 2114 diploid trees in the grafted field collection for which data were available. The 198 trees capture 192 of the 232 total microsatellite alleles and have 78 of the 95 phenotypic characters. An addition of 67 specific individuals increases the coverage to 100% of the allelic and phenotypic character states. Several de novo core sets that capture all the allelic and phenotypic character states in 100 individuals are also provided. Use of these proposed sets of individuals will help ensure that a broad range of Malus diversity is included in evaluations that use the core subset of grafted trees in the PGRU collection.

    DIHYDROCHALCONES IN MALUS MILL. GERMPLASM AND HYBRID POPULATIONS A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Benjamin Leo Gutierrez December 2017 © 2017 Benjamin Leo Gutierrez DIHYDROCHALCONES IN MALUS MILL. GERMPLASM AND HYBRID POPULATIONS Benjamin Leo Gutierrez, Ph.D. Cornell University 2017 Dihydrochalcones are abundant in Malus Mill. species, including the cultivated apple (M. ×domestica Borkh.). Phloridzin, the primary dihydrochalcone in Malus species, has beneficial nutritional qualities, including antioxidant, anti-cancer, and anti-diabetic properties. As such, phloridzin could be a target for improvement of nutritional quality in new apple cultivars. In addition to phloridzin, a few rare Malus species produce trilobatin or sieboldin in place of phloridzin and hybridization can lead to combinations of phloridzin, trilobatin, or sieboldin in interspecific apple progenies. Trilobatin and sieboldin also have unique chemical properties that make them desirable targets for apple breeding, including high antioxidant activity, anti- inflammatory, anti-diabetic properties, and a high sweetness intensity. We studied the variation of phloridzin, sieboldin, and trilobatin content in leaves of 377 accessions from the USDA National Plant Germplasm System (NPGS) Malus collection in Geneva, NY over three seasons and identified valuable genetic resources for breeding and researching dihydrochalcones. From these resources, five apple hybrid populations were developed to determine the genetic basis of dihydrochalcone variation. Phloridzin, sieboldin, and trilobatin appear to follow segregation patterns for three independent genes and significant trait-marker associations were identified using genetic data from genotyping-by-sequencing. Dihydrochalcones are at much lower quantities in mature apple fruit compared with vegetative tissues.

The PBRA Unit is also responsible for assessing the pest potential of plant imports and plant species new to Canada. Risk assessments conducted by the PBRA Unit require biological information about the plant species being assessed. Therefore, these assessments can be done in conjunction with species­specific biology documents that provide the necessary biological information.

Malus classifications differ primarily in the taxonomic level at which infrageneric groupings of species are recognized. Object of the study was oriental apple (Malus orientalis Uglitzk) from Azerbaijan flora which was introduced to Absheron. The conducted experiments showed that the first sprouts of the seeds of the Malus orientalis sown in autumn were observed in the third decade of March. The first embryo roots which gives start to the main roots begin growth in germinal period before the ontogenesis. Thus, experiments have shown that Malus orientalis specie have normal growth in the ontogenesis initial development - germinal stage and it can be used as a perspective species for greening of Absheron. Key Words: Malus orientalis, Absheron, Taxon, Embryo 1. Introduction The genus Malus Mill. comprises 25–47 species, depending upon the rank given to several taxa and the acceptance of putative hybrids. Robinson et al. (2001) explained that the number of species in genus Malus depends upon the rank given to several taxa, species being subspecies and putative hybrids, and the nomenclature of the taxa is complex [1].

    Eleonora Gabrielian & Daniel Zohary Wild relatives of food crops native to Armenia and Nakhichevan Abstract Gabrielian, E. & Zohary, D.: Wild relatives of food crops native to Armenia and Nakhichevan. — Fl. Medit. 14: 5-80. 2004. — ISSN 1120-4052. The paper surveys the variability, ecology, and distribution of the wild relatives of food crops (cereals, legumes, oil and fiber plants, vegetables, condiments, fruits and nut trees) native to Armenia and Nakhichevan. It focuses on the close wild relatives, i.e., members of the primary wild gene pools (GP-1) of the crops. The wild relatives of about 80 crops were surveyed; and the available information on the distribution (in Armenia and Nakhichevan)) of most of these relatives is also illustrated by 93 site distribution maps. Introduction The aim of this paper is to survey the wild relatives of cultivated food plants that occur in Armenia and Nakhichevan (South Trans-Caucasus). We focus on the close wild rela- tives, which are fully (or almost fully) cross compatible and inter-fertile with their related cultigens, and therefore most attractive to the breeders. In other words, this paper is con- cerned mainly with Armenia’s primary wild gene pools (GP-1) of crops. Some of the more distant wild relatives, which according to Harlan and De Wet (1971) definition belong to the secondary and tertiary wild gene pools (GP-2 and GP-3) of their related crops are sometimes mentioned as well; but usually only in brief. Armenia is a relatively small country. However, it is geo-morphologically and ecologi- cally very varied. More over, it is situated on the cross roads between several phytogeo- graphic regions.
