Apples Catalogue 2019
ADAMS PEARMAIN Herefordshire, England 1862 Oct 15 Nov Mar 14 Adams Pearmain is a an old-fashioned late dessert apple, one of the most popular varieties in Victorian England. It has an attractive 'pearmain' shape. This is a fairly dry apple - which is perhaps not regarded as a desirable attribute today. In spite of this it is actually a very enjoyable apple, with a rich aromatic flavour which in apple terms is usually described as Although it had 'shelf appeal' for the Victorian housewife, its autumnal colouring is probably too subdued to compete with the bright young things of the modern supermarket shelves. Perhaps this is part of its appeal; it recalls a bygone era where subtlety of flavour was appreciated - a lovely apple to savour in front of an open fire on a cold winter's day. Tree hardy. Does will in all soils, even clay. AERLIE RED FLESH (Hidden Rose, Mountain Rose) California 1930’s 19 20 20 Cook Oct 20 15 An amazing red fleshed apple, discovered in Aerlie, Oregon, which may be the best of all red fleshed varieties and indeed would be an outstandingly delicious apple no matter what color the flesh is. A choice seedling, Aerlie Red Flesh has a beautiful yellow skin with pale whitish dots, but it is inside that it excels. Deep rose red flesh, juicy, crisp, hard, sugary and richly flavored, ripening late (October) and keeping throughout the winter. The late Conrad Gemmer, an astute observer of apples with 500 varieties in his collection, rated Hidden Rose an outstanding variety of top quality. -

Characterization of Fertile Homozygous Genotypes from Anther Culture in Apple

Doubled haploids can improve the efficiency of breeding and genetic study in apple (Malus ·domestica Borkh.). Seventeen homozygous genotypes were obtained by in vitro anther culture from ‘Senshu’ apple. Flow cytometry analysis revealed that the ploidy level of the anther-derived plantlets was diploid. Simple sequence repeat (SSR) analysis determined the origin and homozygous status of the anther-derived plantlets. The results of S-RNase polymerase chain reaction (PCR)-digestion analysis reinforced the homozygous state. The morphological charac- teristics and reproductive potential of the doubled haploids were investigated. It is especially interesting that one of the doubled haploids derived from anther culture had fertile pollen grains (rate of in vitro germination was 20.6%– 33.0%), and several progenies were obtained from the cross between ‘Prima’ apple and the doubled haploid. The hybridism of these seedlings was confirmed by SSR analysis. Furthermore, the female gametes of the doubled haploid showed slight fertility. -
INF03 Reduce Lists of Apple Varieites

Replies have been received from the following countries: Canada, Czech Republic, Finland, France, Germany, Italy, Netherlands, New Zealand, Poland, Slovakia, South Africa, Sweden, Switzerland and the USA. This note also includes the documents compiled for the same purpose and submitted to the fifty-second session of the Specialized Section. I. Documents submitted to the 52nd session of the Specialized Section A. UNECE Standard for Apples – List of Varieties At the last meeting the 51 st session of the Specialized Section GE.1 the delegation of the United Kingdom offered to coordinate efforts to simplify the list of apple varieties. The aim was to see what the result would be if we only include the most important varieties that are produced and traded. The list is designed to help distinguish apple varieties by colour groups, size and russeting it is not exhaustive, non-listed varieties can still be marketed. The idea should not be to list every variety grown in every country. The UK asked for views on what were considered to be the most important top thirty varieties. Eight countries sent their views, Italy, Spain, the Netherlands, USA, Slovakia, Germany Finland and the Czech Republic. -
Finding List and Guide to Tllc Secrest Arboretum
SPECIAL CIRCULAR 91 MAY 1960 REV ISED Finding List and Guide to tllc Secrest Arboretum Wood Utilization Research Laboratory and Secrest Arboretum Headquarters Effective July 1, 1965, the name of the Ohio Agricultural Experiment Station was changed to: 0 Ohio Agricu ltura I Research and Development Center, ')ll Wooster, Ohio • This page intentionally blank. • GUIBE TO THE SECREST ARBORETUM OHIO AGRICULTURAL EXPERJMENT STATION WOOSTER, OHIO '/ By John E. Aughanbaugh, Harry R. Muckley, and Oliver D. Diller* In May 1950 the forest and ornamental plantings at the Ohio Agricultural Experiment Station were dedicated as the Secrest Arboretum in memory of Edmund Secrest, the father of forestry in Ohio. Since 19o8 these plantings have been expanded to include well over 600 species and varieties of trees and shrubs from many parts of the world. It is the purpose of this publication to serve as a finding list and guide to the Arboretum. The Purpose of the Arboretum One purpose of the Arboretum is to _determine the species and varieties of trees adapted for ornamental, windbreak, and shelterbelt uses in 6hio. There are many varieties of spruces, firs, yews, arborvitae, and other coniferous trees and shrubs growing here for observation by people interested in landscaping and the planting of shelterbelts. Among the more recent additions to the Arboretum is a collection of over 60 varieties of flowering crabapples, 57 selections of hollies and a plot of Chinese dawnredwood. The second purpose of the Arboretum is to determine the spe?ies of trees best adapted for reforestation in Ohio and to determine the silvicultural requirements that will obtain best results in growth and maturity. -
A Life in Horticulture and Plant Breeding: the Extraordinary Contributions of Jules Janick
7 A Life in Horticulture and Plant Breeding: The Extraordinary Contributions of Jules Janick Irwin Goldman Department of Horticulture, University of Wisconsin‐Madison, Madison, WI Rodomiro Ortiz Swedish University of Agricultural Sciences, Department of Plant Breeding, Sweden ABSTRACT This chapter discusses Jules Janick, whose career has been intertwined with enor- mous changes in horticultural science and plant breeding. More than any other person in the U.S. in the last 60 years, Jules Janick has doggedly brought horticul- ture into the scientific realm. Jules Janick was the editor of fourteen volumes of HortScience from 1970 to 1983, and eight volumes of the Journal of the American Society for Horticultural Science from 1976 to 1983. He has edited ten volumes of Acta Horticulturae for the International Science of Horticultural Science (ISHS), and two volumes of Scripta Horticulturae. He also founded and single-handedly edited forty volumes of Plant Breeding Reviews and 43 volumes of Horticultural Reviews, which stand as an extraordinary accomplishment in twentieth century horticulture. Many of his texts still form the foundation for introductory horticul- ture and crop science courses offered around the world. Janick is also the co‐editor, with James Moore, of a number of volumes on fruit breeding, including Advances in Fruit Breeding and Methods in Fruit Breeding. Janick holds six utility patents and 23 plant patents, and one Plant Variety Protection (PVP) certificate. Professor Janick has been a faculty member at Purdue University for over sixty years.

General Administrative Information 1.1 Background 1.2 Scope 1.1 Background The Canadian Food Inspection Agency's Plant and Biotechnology Risk Assessment (PBRA) Unit is responsible for assessing the potential risk to the environment from the release of plants with novel traits (PNTs) into the Canadian environment. 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. When a PNT is assessed, these biology documents serve as companion documents to Dir9408: Assessment Criteria for Determining Environmental Safety of Plants with Novel Traits.
