A cultivar is a kind of cultivated plant that people have selected for desired traits and which retains those traits when propagated. Methods used to propagate cultivars include division, root and stem cuttings, offsets, grafting, tissue culture, or carefully controlled seed production. Most cultivars arise from deliberate human manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word cultivar was coined as a term meaning "cultivated variety".
Horticulture is the art and science of growing plants. This definition is seen in its etymology, which is derived from the Latin words hortus, which means "garden" and cultura which means "to cultivate". There are various divisions of horticulture because plants are grown for a variety of purposes. These divisions include, but are not limited to: gardening, plant production/propagation, arboriculture, landscaping, floriculture and turf maintenance. For each of these, there are various professions, aspects, tools used and associated challenges; Each requiring highly specialized skills and knowledge of the horticulturist.
Floriculture is the study of the efficient production of the plants that produce showy, colorful flowers and foliage for human enjoyment and the human environment. It is a commercially successful branch of horticulture and agriculture found throughout the world. Efficient production practices have been developed over the years, for the hundreds of plant taxa used in the floral industry, increasing the overall knowledge of whole plant biology. Plant breeding and selection have produced tens of thousands of new genotypes for human use. Jasmine, marigold, chrysanthemum, rose, orchid, and anthurium are flowers of commercial demand.
The International Code of Nomenclature for Cultivated Plants (ICNCP) is a guide to the rules and regulations for naming cultigens, plants whose origin or selection is primarily due to intentional human activity. It is also known as Cultivated Plant Code. Cultigens under the purview of the ICNCP include cultivars, Groups, and grexes. All organisms traditionally considered to be plants are included. Taxa that receive a name under the ICNCP will also be included within taxa named under the International Code of Nomenclature for algae, fungi, and plants, for example, a cultivar is a member of a species.
A Group is a formal category in the International Code of Nomenclature for Cultivated Plants (ICNCP) used for cultivated plants (cultivars) that share a defined characteristic. It is represented in a botanical name by the symbol Group or Gp. "Group" or "Gp" is always written with a capital G in a botanical name, or epithet. The Group is not italicized in a plant's name. The ICNCP introduced the term and symbol "Group" in 2004, as a replacement for the lengthy and hyphenated "cultivar-group", which had previously been the category's name since 1969. For the old name "cultivar-group", the non-standard abbreviation cv. group or cv. Group is also sometimes encountered. There is a slight difference in meaning, since a cultivar-group was defined to comprise cultivars, whereas a Group may include individual plants. The cultivar-groups, in turn, replaced the similar category convariety (convar.), which did not necessarily contain named varieties.
The Carnivorous Plant Newsletter is the official publication of the International Carnivorous Plant Society (ICPS), the largest such organization in the world. It is headquartered in Walnut Creek, California.
A cultigen, or cultivated plant, is a plant that has been deliberately altered or selected by humans, by means of genetic modification, graft-chimaeras, plant breeding, or wild or cultivated plant selection. These plants have commercial value in horticulture, agriculture and forestry. Plants meeting this definition remain cultigens whether they are naturalised, deliberately planted in the wild, or grown in cultivation.
The International Union of Food Science and Technology (IUFoST) is the global scientific organization and voice for food science and technology representing more than 300,000 food scientists, engineers and technologists through its work in more than 100 countries. It is a voluntary, non-profit association of national food science organizations. IUFoST is the only elected scientific representative of Food Science and Technology in the International Science Council (ISC), elected by its peers across scientific disciplines. It is the only global representative of food science and technology to notable organizations such as the World Health Organization (WHO), Food and Agriculture Organization (FAO) of the United Nations, United Nations Development Programme and (UNDP), CODEX Alimentarius.
David Willis Robinson was a Northern Irish horticultural scientist who made contributions to the national and international fields of horticulture and agriculture, with more than 120 publications. After a working life in research, in retirement he became a journalist and television/radio presenter and a leader of gardening tours. He cultivated and managed the Earlscliffe Gardens at the Baily, Howth, County Dublin, Ireland.
An International Cultivation Registration Authority (ICRA) is an organization responsible for ensuring that the names of plant cultivars and cultivar groups are defined and not duplicated.
Cultivated plant taxonomy is the study of the theory and practice of the science that identifies, describes, classifies, and names cultigens—those plants whose origin or selection is primarily due to intentional human activity. Cultivated plant taxonomists do, however, work with all kinds of plants in cultivation.
The American Society for Horticultural Science (ASHS) is the world’s premier professional society for horticultural science. Founded in 1903, the mission of ASHS is to promote and encourage national and international interest in scientific research and education in horticulture in all its branches. The more than 4800 ASHS members in all 50 states and 60 countries around the world fulfill this mission by sharing the results of their research, teaching, extension, and community engagement activities with their colleagues and humankind the world over.
The Ulster cherry is a sweet cherry cultivar that originated in the United States.
The rainbow rose is a rose that has had its petals artificially colored. The method exploits the rose natural processes by which water is drawn up the stem. By splitting the stem and dipping each part in water with added dye in different colours, the colors are drawn into the petals resulting in a multicolored rose. With these changes to the rose, it causes them to not live as long as an uncolored rose. The colors are artificial. Besides roses, other cut flowers like the chrysanthemum, carnation, hydrangea, and some species of orchids can also be colored using the same method.
The 'Summerfree' is an apple cultivar first developed in Italy in the 1990s by crossing 'PRI 1956-6' and 'Ed Gould Golden' apples. Resistant to apple scab, it has a spreading habit with moderate vigor, the fruit are large with an average weight of 175 g, the skin is smooth, it ripens one to two months before 'Gala', and it has good storage ability.
The International Society of Zoological Sciences (ISZS) was founded to encourage research, education, and communication in zoology. The society includes both individual scholars, and professional organizations. It particularly tries to increase the availability of research resources and enhance cooperation between different branches of zoology.
The International Society for Photogrammetry and Remote Sensing (ISPRS) is an international non-governmental organization that enhances international cooperation between the worldwide organizations with interests in the photogrammetry, remote sensing and spatial information sciences. Originally named International Society for Photogrammetry (ISP), it was established in 1910, and is the oldest international umbrella organization in its field, which may be summarized as addressing “information from imagery”.
ProMusa was the name originally given to a global program on banana improvement set up by INIBAP in 1997. In 2007, it was restructured as a knowledge-sharing platform coordinated by Bioversity International. It was dissolved in 2021.
Krishna Lal Chadha is an Indian horticultural scientist, author and a former National Professor of the Indian Council of Agricultural Research. He was honored by the Government of India, in 2012, with the fourth highest Indian civilian award of Padma Shri.
