As all traits of a plant are controlled by genes located on chromosomes, conventional plant breeding can be considered as the manipulation of the combination of chromosomes. Plant population management and breeding. The clipboard "plant breeding" created by babalu patel. Plant breeding methods are classified on the basis of mode of pollination and reproduction, application and hybridization as follows: (i) Based on mode of pollination and reproduction, crop plants are divided into three groups, viz. It is a procedure used primarily for breeding selfpollinated species, but can be adapted to produce inbred populations for cross-pollinated species. A selection procedure which is used in segregating population of self-.pollinated species in which material is grown in bulk plot from F 2 to F 5 with or without selection, next generation is grown from bulk seed and individual plant selection is practiced in F 6 or later generations is called bulk method or breeding. If you continue browsing the site, you agree to the use of cookies on this website. Ideally, it will have a new combination of attributes which are significantly better than the varieties already available. Hybrid and Hybrid Breeding- Hybrid - Hybrid is formed by combining the qualities of two different breeds, species or genera through sexual reproduction. In this article we will discuss about the biotechnology in plant breeding. They may influence the choice of the breeding procedure used by the plant breeder. The progress made in molecular plant breeding, genetics, genomic selection and genome editing has contributed to a more comprehensive understanding of molecular markers and provided deeper insights into the diversity available for crops and greatly complemented breeding stratagems. homozygosity.

The F1 hybrid of crosses between different genotypes is often much more vigorous than its parents. It is most suitable for breeding species that are normally closely spaced in production.It is used for field beans and soybeans. Plant breeding - Plant breeding - Hybrid varieties: The development of hybrid varieties differs from hybridization in that no attempt is made to produce a pure-breeding population; only the F1 hybrid plants are sought. 1. Mass selection is a method of breeding in which individual plants are selected on the basis of phenotype from a mixed population , their seeds are bulked and used to grow the next generation. Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Pedigree breeding is a method of genetic improvement of self-pollinated species in which superior genotypes are selected from segregating generations and proper records of the ancestry of selected plants are maintained in each generation. Pedigree refers to record of the ancestry of an individual selected plant. Plant breeding is a highly interdisciplinary science that requires the skills and teamwork of many scientists to be successful. In the conventional plant breeding programme, the development of a new variety or hybrid takes about five to twelve years, starting from inbred production and then hybridization and selection of F 1 hybrids. Unlike MAS, in GS markers are not used for tracking a trait. Plant breeding is the genetic improvement of plants in order to create desired plant types that are better suited for cultivation, give quality yields, tolerate environment pressure and are disease resistant. This methodology also applies molecular markers but in a different fashion in both diploid and polyploid crop species. Selection methods in plant breeding based on mode of reproduction This article needs additional citations for verification. Genomic selection outperformed PS and prediction accuracies ranged from 0.31 and 0.34 for seed yield and plant height to 0.63 for flowering time in a rice collection of 363 elite breeding lines (Spindel et al., 2015), while GS for seed yield in barley resulted similar gains in response to selection as that of PS, but with a shorter breeding cycle time and lower cost (Sallam and Smith, 2016). Plant geneticists consider molecular marker assisted selection a useful additional tool in plant breeding programs to make selection more efficient.

Development of inbred lines Submitted to : Prepared by : Dr. Kalpana Jaggi Jeetendra yadav Kamal timsina 2. In the conventional plant breeding programme, the development of a new variety or hybrid takes about five to twelve years, starting from inbred production and then hybridization and selection of F 1 hybrids. Conventional plant breeding is the development or improvement of cultivars using conservative tools for manipulating plant genome within the natural genetic boundaries of the species. Plant breeders use different methods depending on the mode of reproduction of crops, which include: Self-fertilization, where pollen from a plant will fertilise reproductive cells or ovules of the same plant Vegetative propagated crops which are the most horticultural crops used for food and cash crops are bred to improve human and economic live of a nation. Crop which are propagated asexually or by vegetative means clonal crops.

The F1 hybrid of crosses between different genotypes is often much more vigorous than its parents. Cross-hybridization among Selected Parents. A leap in plant breeding came when ionizing radiation was discovered to modify the genetic make-up of organisms. Selection methods. Initially, early human farmers selected food plants with particular desirable characteristics and used these as a seed source for subsequent generations, resulting in an accumulation of characteristics over time. Standards for organic agriculture do not exclude the use of molecular markers as such, however for the organic sector the appropriateness of molecular markers is not self-evident and is often debated. See our Privacy Policy and User Agreement for details. Hence, the finally selected clone is genetically iden-tical with the original seed plant from which the selected clone is derived. Second, progeny rows are grown from the individual plant selections for observational purposes. Marker-Assisted Selection (MAS) is a used for indirect selection of superior breeding animals. A character such as yield greatly influenced by environment. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

A selection procedure which is used in segregating population of self-.pollinated species in which material is grown in bulk plot from F 2 to F 5 with or without selection, next generation is grown from bulk seed and individual plant selection is practiced in F 6 or later generations is called bulk method or breeding. MAS is based on the concept that it is possible to infer the presence of a gene from the presence of a marker which is tightly linked to the gene of interest. 1 Up until the 20th century, spontaneous mutations were the only source of novel genetic diversity that mankind could exploit in selecting plants and animals suitable for domestication and breeding. Assignment Clipping is a handy way to collect important slides you want to go back to later. Saturated linkage maps have been developed in several crop plants like maize, rice, tomato, wheat, potato, barley, cotton, Brassica etc. Classical plant breeding includes hybridization (crossing) of pure lines, artificial selection to produce plants with desirable characters of higher yield, nutrition and resistance to diseases. Resources for major crop species include detailed, high-density genetic maps, cytogenetic stocks, contig-based physical maps and deep coverage, large-insert libraries 60, 61.These tools have facilitated the isolation of genes via map-based cloning, the localization of quantitative trait loci (QTLs) and the sequencing and annotation of large genomic DNA fragments in several plant species . It is humans selecting desirable traits in a species and choosing which individuals breed in order to increase these traits in the species.• All crops and domesticated animals today are a product of selective breeding… American Society of Agronomy and Crop Science Society of America, Madison, WI.

The advantage of selective breeding is that it uses the processes of natural selection, but under direct supervision from carefully selected animals or plants with the desired traits. There are no genetic modifications or other forms of tampering that could potentially harm people and the risk to the plant or animal is often very minimal at the same time. Plant breeding is a critical tool in the fight for food security and responsible environmental stewardship in the 21st century. 2. In “Crop Breeding” ( D. R. Wood, ed.). Introduction : Inbred line means a relatively stable and pure breeding strain resulting from : Four or more successive generations of controlled self- pollination. Germplasm The greatest service which can be rendered to any country is to add a useful plant to its culture -Thomas Jefferson. The pioneering work of LJ Stadler in the late 1920s marks the beginning of plant mutation breeding, despite Stadler himself being less than optimistic about its real value. Evaluation and Selection of Parent Plants. The intermating of selected F 2 plants restores heterozygosity in the progeny, which provides for a greater opportunity for recombination. 140 In a study by Stuber, 146 using MAS, the QTLs related to maize grain yield were transferred successfully. The combination of these characteristics is expected in the hybrid progeny. Such tentative selective methods were the forerunners of early plant-breeding procedures. The number of genes that control the trait of interest is important to breeders. Purpose of Hybridization: The objectives of hybridization can be categorized under 3 major criteria: 1.
