Basis of Selection: In this method, selection of superior plants is based on the progeny performance (genotype).Those plants whose progeny performance is superior for the character under consideration are bulked together to produce the next generation.

However, that would have taken decades longer, during which breeders would have had to spend a lot of time breeding out unde-sirable traits. Meuwissen, B.J. PDF | On Jan 1, 2015, M. Messmer and others published Plant Breeding Techniques | Find, read and cite all the research you need on ResearchGate The bulk-population method of breeding differs from the pedigree method primarily in the handling of generations following hybridization. Types 4. Recurrent selection :- Method which involves reselection generation after generation with interbreeding of selects to provide for genetic recombination. T.H. Lec 03 – Apomixis – classification and significance in plant breeding. The new variety may have higher yield, improved grain quality, increased disease resistance, or be less prone to lodging. Merits and Demerits. Lec 02 – Modes of Reproduction. Ideally, it will have a new combination of attributes which are significantly better than the varieties already available. Abstract: Genomic Selection (GS) is a method in plant breeding to predict the genetic value of untested lines based on genome-wide marker data. This method successfully improved the sugar content in sugar beet. 4. ),2nd Semester Reg. BMC Genet., 13 (2012), p. 100. Genetic markers in plant breeding: Conceptions, types and application Genetic markers are the biological features that are determined by allelic forms of genes or ge‐ netic loci and can be transmitted from one generation to another, and thus they can be used as experimental probes or tags to keep track of an individual, a tissue, a cell, a nucleus, a chromo‐ some or a gene. Methods of plant breeding in the genome era SHIZHONG XU*ANDZHIQIU HU Department of Botany and Plant Sciences, University of California, Riverside, CA 92521, USA (Received 5 October 2010 and in revised form 17 October 2010) Summary Methods of genomic value prediction are reviewed. Introduction to Recurrent Selection: The initial idea about recurrent selection was independently given by Hayes and Garber in 1919, and East and Jones in 1920. 3. Lec 05 – Classification of plants Selection within Existing Crossbred Population 463. Plant breeding can be broadly defined as alterations caused in plants as a result of their use by humans, ranging from unintentional changes resulting from the advent of agriculture to the application of molecular tools for precision breeding. 3. The most Our objectives are to (i) give a brief introduction … your selections! Breeding methods such as selection, hybridisation, mutation breeding and poly-ploidy breeding have been employed in cardamom improvement. In this chapter we are concerned with the methods by which new varieties of self-pollinated crop plants originate. Book Detail: Language: English Pages: 199 Author: TNAU Price: Free How to Download PDF Book [Full Guide] Course Outline: Principles of Plant Breeding. ¥Not the case for traits (i.e., yield) scored after pollination. Future Breeding Plan for Genetic Improvement of Crossbred Cattle 462. The method has been widely explored with simulated data and also in real plant breeding programs. Concluding remarks 23 4. Thus it is a cyclic selection that is used to improve the frequency of desirable alleles for a character in a breeding population. … The procedure of recurrent selection was described […] The goals of plant breeding are to produce crop varieties that boast unique and superior traits for a variety of agricultural applications. The Future of Conventional Plant Breeding 14. Individual plant selection is continued till the progenies become homozygous, and they show no segeration. Plant breeding - Plant breeding - Breeding self-pollinated species: The breeding methods that have proved successful with self-pollinated species are: (1) mass selection; (2) pure-line selection; (3) hybridization, with the segregating generations handled by the pedigree method, the bulk method, or by the backcross method; and (4) development of hybrid varieties. Plant breeding is a method of altering the genetic pattern of plants to increase their value and utility for human welfare. Germplasm introduction and its Use 4 62. Topics such as biotechnology in plant breeding, intellectual property, risks, emerging concepts (decentralized breeding, organic breeding), and more are addressed in the new, updated edition of this text. Term coined by Hull (1945) & procedure described by Jenkins (1940). One important difference between cisgenesis and genetic modification (transgenesis) is that cisgenesis stays within type boundaries. Article Download PDF CrossRef View Record in Scopus Google Scholar. methods (cross-breeding and selection). (Agri. • Vegetatively ‐propagated plants still need to be flowered in order to create new variation that is heritable ... • Only breeding method in which the results are both predictable and repeatable. Plant breeding is the use of natural and artificial selection to produce heritable variations and novel combinations of alleles in plants and to identify plants with novel and useful properties. GoddardPrediction of total genetic value using genome-wide dense marker maps. His method was called as vilmorin isolation principle. Generally, 10-50 seeds of each selected plant are grown for progeny testing. Methods of breeding ... some valuable varieties.During 1857 Hallet in England practiced single plant selection in wheat, oats and barley and developed several commercial varieties. Plant Breeding Definition. In this article we will discuss about:- 1.
