Plant breeding is the use of natural and artificial selection to produce heritable ... As agriculture began to take hold and human populations increased, the most basic forms of plant breeding were employed as the most efficient calorie-conferring plant varieties were selected from wild stands, with seeds saved and replanted. One example is the selection of dwarf, early maturing varieties of rice. and A. H./B. Once the genetic engineer gives the transgenic plant to the plant breeder, it takes the breeder at least two or three years to derive a backcross line that is the genetic equivalent of the elite line plus the event. Be the first to write a review. Introduction to Basic Plant Breeding provides a review of plant reproduction, genetic variation, gene banks, germplasm preservation, gene segregation, the power of selection and its role in plant breeding, and an introduction to intellectual property and its role in the life of a plant breeder.

Plant Reproductive Systems. Ph.D programme in Agricultural Botony was started in the year 1973. This “biofortification” of food crops, a term which also includes genetic modification, has been shown to improve nutrition and is especially useful in developing areas where nutritional deficiencies are common and medical infrastructure may be lacking. Furthermore, their early maturity frees the land quickly, often allowing an additional planting of rice or other crop the same year. It is a science which uses the knowledge and techniques from many basic science areas. The most important factor for basic selective breeding is genetic variation in the characteristic of interest.

Such processes, repeated over many generations, can change the hereditary makeup and value of a plant population far beyond the natural limits of previously existing populations. Plant breeding is a technique through which genetic traits of a plant are changed. 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.
