Plant Breeding Systems: What Are They?

Plant breeding is the application of genetic principles to produce plants that are more useful to humans. This process involves selecting economically or aesthetically desirable plants, controlling the mating of selected individuals, and then selecting certain individuals among the progeny. Plant breeding is the science-driven creative process of developing new plant varieties, known as cultivar development, crop improvement, and seed. Plant breeders develop new varieties that are productive, nutritious, and adapted to a changing climate by combining field-based methods.

Plant breeding is an ancient activity that originated as our ancestors shifted from gathering wild plants to growing them in a controlled manner. Modern plant breeders are human-directed selection in genetically variable populations of plants. Breeding systems are important aspects of the natural biology of organisms, affecting homozygosity and thus many aspects of their health.

Plant breeding is the process of altering the traits of plants to produce desired characteristics. It has been used to improve the quality of food products and to improve the genetic makeup of plants. Plant breeding systems include the evolution and diversity of reproduction modes in flowering plants.

Breeding systems are often neglected but are crucial aspects of the natural biology of organisms, affecting homozygosity and many aspects of their health. Plant breeding is a method of altering the genetic pattern of plants to increase their value and utility for human welfare. This process may be carried out using a wide variety of methods and techniques.

What is plant breeding method?

Plant breeding involves manipulating plant qualities to create new varieties with desired characteristics. Higher-quality plants are selected and crossed to achieve desired quality, resulting in a population with improved traits. Major objectives of plant breeding include:

1. Increasing plant diversity and quality
2. Enhancing plant resistance to disease
3. Increasing plant productivity and yield
4. Enhancing plant health and productivity

What is a plant breeding program?

Plant breeding programs in Soil and Crop Sciences aim to improve crop characteristics by altering the genetic composition of plants. Faculty members use conventional and molecular breeding techniques to modify targets such as yield potential, crop quality, biotic and abiotic stress resistance, and reduced production costs. They also develop, assess, adapt, and incorporate new technologies like drone-based imaging. Grain crop breeders have developed varieties that improve grain yield, resistance to diseases and pests, lodging resistance, and nutrition or processing quality.

Bioenergy crop genotypes have been developed, such as sweet sorghums, sugar cane, forage sorghums, and perennial grasses, with exceptional sugar production per unit land area for ethanol production or biomass for cellulosic ethanol production. Cotton breeders and geneticists have developed unique interspecies lines and strains with exceptional fiber quality and drought tolerance.

What are the two types of plant breeding?

Plant breeding processes include inbreeding, backcrossing, mutation breeding, hybrid breeding, and genetic engineering. Gregor Mendel, considered the “father of genetics”, developed inheritance laws through plant hybridization experiments. Genetics has been instrumental in enhancing crop production through plant breeding. Genetic modification involves adding or degrading genes to produce desirable phenotypes. Transgenic plants are those resulting from gene addition, while cisgenic plants are those using modified genes to control their native promoter.

Genetic modification can sometimes produce plants with specific traits faster than classical breeding, as the majority of the plant’s genome remains unchanged. Gregor Mendel is considered the “father of genetics” in this field.

What are the four types of breeding?

The term “outbreeding” can be classified into four distinct categories: species cross, crossbreeding, outcrossing, and grading up. A species cross involves the crossing of different species, whereas crossbreeding involves the mating of established breeds. Outcrossing, in contrast to inbreeding, involves the mating of unrelated animals within the same breed.

What are the plant breeding breeding systems?

Steps for Different Plant Breeding MethodsCollection of Variability. … Evaluation and Selection of Parents. … Hybridization. … Selection and Testing of Superior Recombinants. … Testing Release and Commercialization of New Cultivars.

Did you know we can actually change the biological makeup of plants and crops to increase their yield and usefulness? In fact, most of the crops grown in India, such as wheat and rice, have undergone plant breeding during the Green Revolution. Let us take a look.

Plant breeding is a method of altering the genetic pattern of plants to increase their value and utility for human welfare. It is a purposeful manipulation of plants to create desired plant types that are better suited for cultivation, give better yield and are disease resistant. Plant breeding is done for the following objectives –

• Increase the crop yield
• Improve the quality of the crop
• Increase tolerance to environmental conditions like salinity. extreme temperatures and drought
• Develop a resistance to pathogens
• Increase tolerance to the insect pest

Who benefits from plant breeding?

Plant breeding is a crucial field that aims to modify and improve plant species to meet human needs and wants. It is essential for our survival and sustainable agricultural use, as it helps develop resistance to diseases, pests, drought, and temperature extremes, and improves quality factors that positively impact people worldwide. Plant breeding also helps adapt crops to new locations, improving food security and supporting local and regional food systems. Plant breeders also serve as a vital link between farmers and consumers, developing traits that make farming easier and more efficient, and increase consumer satisfaction with the resulting product.

Plant breeding became an academic discipline about 100 years ago, following the rediscovery of Mendel’s laws. It has been studied and practiced in various locations, including governments, universities, private sector seed companies, and hobbyists and gardeners. The University of Wisconsin offers formal training in plant breeding and plant genetics since 1968, with membership from agronomy, biochemistry, botany, forest and wildlife ecology, genetics, horticulture, plant pathology, and statistics. Research areas include biochemical and molecular genetics, biometry, quantitative genetics, cytogenetics and cytology, genetics, and plant breeding.

What are two breeding systems?

Two-breed terminal systems involve crossing straight-bred females with bulls from different breeds, producing F1 offspring. This simple system requires one breeding pasture, one sire breed, and minimal labor and management. Three-breed terminal systems, similar to two-breed terminal, require cows to be crossbred (AxB) and mate them to sires of another breed. This system yields more heterosis in cow and calf, improving growth rate and reproduction. It requires only one breeding pasture and provides 100 individual and maternal heterosis.

What is the breeding system?

Breeding systems are methods used to evaluate and select desired genetic traits in a breed or species. They are crucial in addressing health issues in purebred dogs, congenital heart diseases in north Indian populations, and understanding the homoeologous relationships of rice, wheat, and maize chromosomes. These systems are essential in ensuring the health and longevity of breeds and species.

What is an example of plant breeding?

The crossing of a high-yielding pea with a mildew-resistant one results in progeny, which are then crossed to their high-yielding parent.

What is plant breeding?

Plant breeding is the manipulation of plant species through pollination, genetic engineering, and selection of progeny to create new and improved genotypes and phenotypes with desirable characteristics like disease or insect pest resistance, salt or draught tolerance, and crop growth. This science is used to create new and improved plant genotypes and phenotypes with desirable characteristics. Copyright © 2024 Elsevier B. V., its licensors, and contributors.
