Plant breeding, in its simplest definition, is crossing two plants to produce offspring that, ideally, share the best characteristics of the two parent plants. People caused changes in the plants that were used for agriculture and, in turn, those new plant types allowed changes in human populations to take place. Introduction to Plant Breeding Master Gardener Training. … Plant introduction Definition Taking a genotype or a group of genotypes in to a new place or environment where they were not grown previously. Learning Objective Page. Germplasm The greatest service which can be rendered to any country is to add a useful plant to its culture-Thomas Jefferson. Learning Objective Page. The specific objectives may vary greatly depending on the crop under consideration. Plant breeding can be considered a coevolutionary process between humans and edible plants. regulatory status of products generated from several new plant breeding techniques. E.g. Lec 04 – Modes of Pollination. Sparnaaij, L.D. The only advantage of following a commercial crop on station is that a commercial crop is expected to leave the land highly uniform. (1976). genetic mapping, and research) 2. Plant breeding is time-consuming and costly. Lecture 14 - Role of Heterosis and its exploitation . An established breeding program with clear aims and reasonable resources will produce a new variety regularly, every couple of years or so. Be the first one to write a review. Genetic modification is frequently used in these techniques but only as a tool during the breeding process. In the latter half of the 20th century, plant breeders incorporated techniques aimed at increasing diversity and expediting the breeding process. comment. New Age International Pvt Limited, 1998 - 432 pages. Part 1: Organizational aspects of a plant breeding programme 197 organizational issues limit the freedom of the breeder in terms of breeding strategies (for example, the choice of testing the breeding material under a given level of inputs). New plant breeding tools will be accessible to smaller enterprises if the resulting plant varieties are not regulated according to 2001/18/EC E.g. • Plant breeding is the art and science of changing and improving the heredity (genetic abilities) and performance of plants. The object of hybridization is to combine desirable genes found in two or more different varieties and to produce pure-breeding progeny superior in many respects to the parental types. Acta Hortic. Throughout the history of civilization, plant breeding has helped farmers solve complex challenges while also appeasing the appetites of consumers. Upon crossing, these parental lines can reconstitute the original genetic composition (Fig. Some examples: breeding is the evolution by the will of man (Vavilov 1935); plant breeding is the genetic adjustment of plants to the service of man (Frankel 1958); plant breeding is a unique science in at least two ways. UWA-Plant Production Systems Workshop Barley Doubled Haploids Key activities 1. 002 Agricultural Research & Technology: Open Access Journal How to cite this article: Melese Lema. In addition, under changing environmental conditions plant breeding is even more desirable for the development of crop varieties resistant to multiple environmental stresses ( Ceccarelli et al., 2010 ). Selfing and crossing are essential in crop breeding. Thus, this book … Reviews There are no reviews yet. Following the works of Thomas Hunt Morgan and Hermann Muller in the 1910’s and 1920’s, plant breeders saw the value of physical and chemical mutagenesis for the production of new phenotypes. Lecture 13- Breeding for Disease Resistance . or Science of changing and improving the heredity of plants Aim : Plant breeding aims to improve the characteristics of plants so that they become more desirable agronomically and economically. "Precision plant breeding" seems to be very interesting but must be a technique/tool in molecular plant breeding. Start with a seed. Thus introduction may involve new varieties of a crop already grown in that area, a wild relative of the crop species or totally a new crop species for that area. Lec 05 – Classification of plants. • Breeding can also be defined as the use of techniques involving crossing plants to produce varieties with particular characteristics (traits), which are carried in the genes of the plants and passed on to future generations. Conventional plant breeding has been the method used to develop new varieties of crops for hundreds of years However, conventional plant breeding can no longer sustain the global demand with the Increasing population, Decline in agricultural resources such as land and water, and the Decreasing of the yield curve of the staple crops Thus, new crop improvement technologies should be … Topic 13. 1 B&C), homozygous parental lines are derived from this plant. Plant breeding - Plant breeding - Hybridization: During the 20th century planned hybridization between carefully selected parents has become dominant in the breeding of self-pollinated species. They can shorten breeding programmes considerably, depending on the crop and the plant traits targeted, sometimes from decades to years. Lec 03 – Apomixis – classification and significance in plant breeding. Plant breeding techniques are extremely successful and have been widely used in agriculture to enhance the yield of several crop plants over the past five decades (Jaggard et al., 2010). Production of DH for breeding and special purpose crosses (eg. The exact procedure that he may use to ensure self or cross pollination of specific plants will depend on the particular species with which he is working. DNA based markers, tissue culture techniques are used by smaller enterprises Why an important question? Plant breeding history and methods.. Statistical and Biometrical Techniques in Plant Breeding. Plant breeding deals with the genetic improvement of crop plants also known as science of crop improvement. Front Cover. 1 A). Some desirable traits are incorporated to produce a new variety. Following the green revolution and transgenic crop development, another revolutionary progress has been experienced in plant breeding in the last decade with the application of marker-assisted selection (MAS), next-generation sequencing (NGS), and gene editing techniques together with omic technologies, including genomics, transcriptomics, proteomics, and phenomics.
