This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The pear (Pyrus communis L.) is a typical fruit of temperate regions, having its origin and domestication at two different points, China and Asia Minor until the Middle East. It is the fifth most widely produced fruit in the world, being produced mainly in China, Europe, and the United States. Pear belongs to rosaceous family, being a close “cousin” of the apple, but with some particularities that make this fruit special with a delicate flavor. Thus, it deserves a special attention and a meticulous review of all the history involved, and the recent research devoted to it, because of the economic and cultural importance of this fruit in a range of countries and cultures. Therefore, the purpose of this literature review is to approach the history of the origin, domestication, and dispersal of pears, as well as reporting their botany, their current scenario in the world, and their breeding and conservation.

INTRODUCTION Crop plants are our greatest heritage from prehistory (Harlan 1992; Diamond 2002). How, where, and when the domestication of crops plants occurred is slowly becoming revealed although not completely understood (Camp et al. 1957; Smartt and Simmonds 1995; Gepts 2003). In some cases, the genetic distance between wild and domestic plants is so great, maize and crucifers, for example, that their origins are obscure. The origins of the ancient grains (wheat, maize, rice, and sorghum) and pulses (sesame and lentil) domesticated in Neolithic times have been the subject of intense interest and the puzzle is being solved with the new evidence based on molecular biology (Gepts 2003).

  • Superior Growth Characteristics, Yield, and Fruit Quality in Promising European Pear ( Pyrus Communis L.) Chance Seedlings in Iran
    J. Agr. Sci. Tech. (2015) Vol. 17: 427-442 Superior Growth Characteristics, Yield, and Fruit Quality in Promising European Pear ( Pyrus communis L.) Chance Seedlings in Iran ∗ R. Najafzadeh 1, and K. Arzani 1 ABSTRACT Selection of superior chance seedling genotypes is an important task in pear breeding programs. This research was carried out in order to explore and evaluate some of European pear ( Pyrus communis L.) chance seedling genotypes that are primarily used as rootstock for the Asian pear ( Pyrus serotina Rehd.) in Tarbiat Modares University (TMU) Asian Pear Collection Orchard. After four years visual observations of the genotypes, the evaluation process started on the pre-selected genotypes in order to identify the superior promising individuals during 2009 and 2010 growing seasons. Selected chance seedling genotypes were A 95 , A 101 , A 189 , A 195 , and A 374 . A local commercial cultivar `Shahmiveh’ was used as a reference and labeled as A 238 in the evaluation program database. Results showed significant differences among the studied genotypes in most of the evaluated characters. Among the studied genotypes, genotype A95 showed indications of appropriate fruit physicochemical properties and higher fruit quality compared with the reference cultivar. Good fruit aroma as well as a reddish background skin color, highest acidity and lowest pH among the examined genotypes were other superior characters of A 95 . Based on the measured characters compared with `Shahmiveh' as a good reference commercial Iranian pear cultivar, we conclude that A 95 showed superiority and higher rank in flavor, fruit color, and attractiveness. Also, this promising genotype showed a good productivity potential in terms of producing higher yield with a suitable supporting vigor.

  • Pest Risk Assessment of Monilinia Fructicola for the EU Territory and Identification and Evaluation of Risk Management Options1
    EFSA Journal 2011;9(4):2119 SCIENTIFIC OPINION Pest risk assessment of Monilinia fructicola for the EU territory and 1 identification and evaluation of risk management options EFSA Panel on Plant Health (PLH)2, 3 European Food Safety Authority (EFSA), Parma, Italy ABSTRACT The EFSA Panel on Plant Health has delivered a pest risk assessment on the risk posed by Monilinia fructicola to the EU territory and has identified risk management options and evaluated their effectiveness in reducing the risk to plant health posed by this organism. The Panel has also analysed the effectiveness of the special requirements presently listed in Annex IV, Part A, Section I of Council Directive 2000/29/EC, in reducing the risk of introduction of this pest into the EU territory. The Panel concluded that the main pathways for entry into the EU territory are plant material for propagation purposes and fruit of host genera and that, with the exception of dried fruit, the probability of entry is very likely. The probability of establishment is also very likely due to the suitable environmental conditions and to the widespread presence of host species, susceptible for most of the year, on most of the risk assessment area. Cultural practices and control measures currently applied and competition with other Monilinia species cannot prevent the establishment of M. fructicola. The probability of spread is very likely because of the multiple ways of dispersal of the pest. The overall impact in the endangered area is estimated to be moderate. Neither additional cultural measures nor increased fungicide treatments would be needed to control of brown rot in the orchard after the introduction of M.

  • Research Directions Based on the Current State of Pear Production and Rootstock Research RACHEL ELKINS', RICHARD BELL and TODD EINHORN3
    153 Journal of the American Pomo logical Society 66(3): 153-163 2012 Needs Assessment for Future US Pear Rootstock Research Directions Based on the Current State of Pear Production and Rootstock Research RACHEL ELKINS', RICHARD BELL AND TODD EINHORN3 Abstract The area devoted to pear production in the United States (U.S.) is declining due to lack of precocity and high cost of production. The U.S. pear industry currently lacks "modern" orchard systems characterized by compact trees that produce early, high yields of large, high quality fruit. Tall, shaded canopies are not economically sustain- able and are at a competitive disadvantage for attracting and sustaining a labor supply. There is broad and deep consensus in the pear industry that developing size-controlling rootstocks isimperative to remain competitive na- tionally and globally. Currently employed rootstocks in the U.S. are Pyrus communis seedlings and clones, none of which achieve more than about a one-third size reduction, and P betulifolia seedlings. Quince (C. oblonga), used with interstems in Europe and South America, is utilized commercially (without interstems) in the U.S. only for 'Cornice' in southern Oregon and northern California. This is due primarily to a lack of cold hardiness needed in more northern production areas, a lack of graft-compatibility with the other major scion cultivars, fire blight and iron chlorosis susceptibility, and relative lack of productivity versus other rootstocks, especially in Califor- nia.Current evaluative trials rely on older U.S. and imported selections, and include the NC-140 Multistate Rootstock Research Project and several individual programs in California, New York, Oregon and Washington.

For some important crops, the Centre of diversity of related wild species is also presented. These wild species are important sources of genes useful to man when incorporated in cultivated crops. Hence such wild species have to be included in genitor collections for breeding. For some cultivated species, the region of diversity could not be identified. Future research may show where they have come from.
