history of plant breeding slideshare

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. Mendelian era:- 1900 to 1920. This was the first step toward plant breeding at a global level. I then transferred this pollen to the pistil (female flower part) of another alfalfa plant. 2002. - Plant breeding began when man first choose certain plants for cultivation. conventional breeding, and some of the implications for safety, in more detail. - Variety in genetic structure enhances viability against disease, pests, climate variability.- Selection is the process that plants with desirable characteristics are chosen from a population and then reproduced. Assessment of potentials and constraints for development and use of plant biotechnology in relation to plant breeding and crop production in developing countries. FAQ; About; Contact US Germplasm The greatest service which can be rendered to any country is to add a useful plant to its culture-Thomas Jefferson. One of the most important breakthroughs in the history of genetics was the discovery of experimental mutagenesis in the early 20 century, which later brought about plant mutation breeding. Working paper. Early teosinte plants (about 5000BC) had small cobs with few kernels, but by 1500AD, the corn cobs were more than 5 times the size and packed full of sweet, juicy kernels. Alternatively whole plants or seedlings are irradiated in a gamma greenhouse (Fig 3) or a gamma field (Fig 4), a process called chronic irradiation. Plant breeding is a highly interdisciplinary science that requires the skills and teamwork of many scientists to be successful. 1992. HISTORY OF PLANT BREEDING PRESENTED BY: Pawan Nagar Reg. Most of our major food crops are derived from the domesticated varieties. The F1 hybrid of crosses between different genotypes is often much more vigorous than its parents. DANIDA. Plant breeding is defined as identifying and selecting desirable traits in plants and combining these into one individual plant. Bauman, F. and Crane, P.L. Embryo rescue is one of the earliest and successful forms of in-vitro culture techniques that is used to assist in the development of plant embryos that might not survive to become viable plants. 2) or they are irradiated in X-ray machines. center of diversity, center of origin, plant evolution, germplasm, plant breeding, plant exploration Abstract. Mendel's work in genetics ushered in the scientific age of plant breeding. larger seed, better taste, easier harvestability) to those of natural adaptation, fitness and offspring. Breeding has been practiced since the early human civilization and selection was the first method of breeding, adding the criteria of suitability for man’s use (e.g. N.I.

A century ago the science of plant pathology was just being born and L. R. Jones wondered, at a meeting in Atlanta in 1913, whether it was a good thing to separate plant pathology as a discipline from botany (8). - The process of bringing a wild species under human management is referred toas Plant tissue culture, or the aseptic culture of cells, tissues, organs, and their components under defined physical and chemical conditions in vitro, is an important tool in both basic and applied studies as well as in commercial application. Organic farming, agricultural system that uses ecologically based pest controls and biological fertilizers derived largely from animal wastes and nitrogen-fixing cover crops.
