selection methods in plant breeding pdf

The bulk-population method of breeding differs from the pedigree method primarily in the handling of generations following hybridization. Briefly, the pedigree method involves extensive single plant selection and trait screen-ing during segregating generations until yield testing.

First, a large number of selections are made from the genetically variable original population. Plant breeding is selection made possible by the existence of variability. Disadvantages include a tendency to overestimate values when data is MAS breeding method depends on the indirect selection methods in which a trait of interest is selected based on morphological, biochemical, or DNA/RNA variations. or Plant breeding is the art and science of improving the heredity of plants for the benefit of mankind.

Filter writers by a subject area 70%. Method of Plant Breeding in Self Pollinated Plants - Pedigree Methods Mass selection and pure line selection cannot be applied to segregating population. This method of selection depends mainly on the selection of plants according to their phenotype and performance. l Use of haploid cells and tissues for increasing genetic variation by mutation. Conventional Methods of Plant Breeding Conventional Methods Self Pollinated Crops-In self-pollinated crops,selection permits reproduction only of those plants that have the desirable characteristics,i.e.,the plants that have been selected. The topics mainly covered includes general genetics, genome organization of crop plants, cytogenetics of crop plants, reproduction and pollination methods, plant breeding methods, population and quantitative genetics principles, biometrical genetics, plant breeding for stress resistance and nutrional quality, genetic engineering and . In agriculture, the breeding worth (or net genetic merit) of a candidate for selection depends on several traits. Population breeding approach similar to the recurrent selection approach used in allogamous species . A method of crop improvement in which individual desirable plants are selected on the basis of phenotype from a mixed population, their seeds are bulbed and used to grow next generation is called mass selection. l DHs for genomic selection and genomic prediction. Modern Methods of Plant Breeding Traditional Breeding Cross-pollination between different plants within the same species. 2. Briefly describe various objectives of plant breeding with examples. The most important methods of breeding cross-pollinated species are (1) mass selection; (2) development of hybrid varieties; and (3) development of synthetic varieties. Inbreeding. It typically takes more than ten years for a variety to proceed from the initial breeding stages through to commercial release. 6. In short, plant breeding is the manipulation of a biological system that requires many generations to achieve results. An established breeding program with clear aims and reasonable resources will produce a new variety regularly, every couple of years or so.

Therefore, during primitive time plant breeding was largely an art and very less science was involved in that, but the present breeding methods are entirely A selection method to select for one trait until the trait is at a satisfactory achievement. At the end of bulking period(U p to F6 - F8), individual plants are selected and evaluated in a similar manner as in the pedigree method of breeding. Nowadays these procedures range from very simple mass selection methods, sometimes applied in an ine?ective way, to indirect trait selection based on molecular markers. Plant breeding was practiced first when people learned to look for superior plants to harvest for seed; thus selection became the earliest method of plant breeding.

Innovations include marker-assisted selection (MAS), a method that allows breeders to easily track the genes that lead to improvements in plant characteristics, such as disease resistance and product quality. Therefore, during primitive time plant breeding was largely an art and very less science was involved in that, but the present breeding methods are entirely Thus, conventional breeding is essen­ tially the normal mating process, but it is manipulated through human choice of the parents and selection of Since cross-pollinated species are naturally hybrid (heterozygous) for many traits and lose vigour as they become purebred (homozygous), a goal of each of these breeding methods . 196 Plant breeding and farmer participation 9.1 INTRODUCTION The topics covered in this chapter are seldom described in standard plant breeding books, as they arise after the basic choices Plant Breeding The Production of New crop varieties which are Superior to their Parents. 4.
