This article emphasizes the application of genetic principles to the improvement of plants; the biological factors underlying plant breeding are dealt with in the article heredity. Plant breeding — the science of maximizing plants’ positive genetic traits to produce desirable effects — continues to open new frontiers in agricultural production. Thus the breeder can rarely focus attention on any one characteristic but must take into account the manifold traits that make the plant more useful in fulfilling the purpose for which it is grown. Another common goal of plant breeding is to extend the area of production of a crop species.

Search this Forum: Advanced Search. M.Sc. Uniformity in maturity is, of course, essential when crops such as tomatoes and peas are harvested mechanically. This is accomplished by selecting plants found to be economically or aesthetically desirable, first by controlling the mating of selected individuals, and then by selecting certain individuals among the progeny. 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. Plant breeders’ rights (PBR), also known as plant variety rights (PVR), are intellectual property rights granted to the breeder of a new variety of plant. This will be a group problem solving session focused on designing large-scale plant breeding or germplasm screening trials. These remarkable transformations were accomplished by early plant breeders in a very short time from an evolutionary point of view, and the rate of change was probably greater than for any other evolutionary event. method of altering the genetic pattern of plants to increase their value and utility for human welfare The breeder of horticultural plants must also consider aesthetic appeal. Updates? Is there a standard of ethics in plant breeding? The results of early plant-breeding procedures were conspicuous.
