Plant breeders, also known as geneticists, conduct scientific research into plant and crop-based agriculture to improve breeding techniques and develop new strains of crops. They work to develop disease and drought resistant crops while increasing yields to meet consumer needs. As a plant breeder/geneticist, one must produce research aims and objectives, predict the cost of work, and identify research methods and techniques for improving plant breeding.
Plant breeders and geneticists experiment with plant species using advanced genetics expertise, tools, and techniques to achieve their objectives. They study plant DNA to improve plant characteristics for agricultural and research purposes. By studying a plant’s DNA, they can examine ways to improve shape, size, production level, pesticide, and disease resistance. Plant breeders can now precisely modify specific genes in plants, leading to faster and more targeted breeding efforts. This technology has the potential to create crops with enhanced nutritional content.
Plant breeding is an ancient activity that originated when our ancestors shifted from gathering wild plants to growing them in a controlled manner. Modern plant breeders are responsible for developing new plant varieties with improved characteristics through genetic engineering. They work on improving the quality and performance of existing agricultural and horticultural crops and creating new varieties of plants.
Plant breeders focus on creating specific outcomes of plants and potentially new plant varieties, narrowing down the genetic information to maximize positive traits. They use plants as models or focal organisms instead of animals, selecting those with the greatest potential based on performance data, pedigree, and more sophisticated genetic information. Plant breeding continues to open new frontiers in agricultural science, with plant geneticists studying genetics in botany.
📹 An Introduction To Plant Breeding
Plant breeding is a technique through which genetic traits of a plant are changed. Some desirable traits are incorporated to …
What is genetic breeding?
Breeding is the application of genetic principles in animal husbandry, agriculture, and horticulture to improve desirable qualities. It began with selective cultivation in ancient times and now focuses on pollination. Animal breeding involves choosing ideal traits, selecting breeding stock, and determining the breeding system, such as crossbreeding or inbreeding. This article was recently revised and updated by Robert Curley.
Is plant breeding the same as plant genetics?
Plant breeding is the application of genetic principles to produce plants that are more useful to humans. This involves selecting economically or aesthetically desirable plants, controlling the mating of selected individuals, and selecting certain individuals among the progeny. Repeated over many generations, these processes can change the hereditary makeup and value of a plant population far beyond the natural limits of previously existing populations.
Plant breeding is an ancient activity dating back to the beginnings of agriculture, with humans recognizing degrees of excellence among plants and saving seed for planting new crops. Early plant-breeding procedures were conspicuous, with most present-day varieties being so modified from their wild progenitors that they are unable to survive in nature. These remarkable transformations were accomplished by early plant breeders in a very short time, with the rate of change likely greater than for any other evolutionary event.
What is a plant geneticist?
A plant geneticist is a scientist who studies genetics in botany, using genes to isolate and develop specific plant traits. They work to improve breeding methods to ensure future generations possess desired traits. Plant genetics has played a significant role in modern-day theories of heredity, starting with Gregor Mendel’s 19th-century study of pea plants. Today, the occupation encompasses advancements in biotechnology, leading to better understanding of plant breeding and hybridization. Commercially, plant geneticists develop methods to make produce more nutritious or alter plant pigments to appeal to consumers.
What is plant breeding in genetics?
Genetics is a branch of biology that studies heredity and genetic variation, as well as the molecular level of gene function in crop/model plants. Plant breeding is the targeted modification of plant species to create desired genotypes and phenotypes useful for mankind. The Department of Genetics and Plant Breeding aims to inspire students to improve and develop new plant varieties to address food security, climate change, and sustainability. Through course work in classes, greenhouses, field, and labs, students gain experience and research opportunities, while also connecting with resourceful teachers and researchers.
This leads to career opportunities in industry, public government, and university sectors, with collaboration at local, federal, and international levels. Plant breeders have the unique opportunity to improve agriculture by improving agriculture.
What is the salary of plant geneticist in India?
The mean annual income for a plant breeder in India, between the ages of 1 and 13, is approximately ₹2. The salary range is from 4 Lakhs to ₹12. The average annual salary for this position is ₹5, 000. The average annual salary for a plant breeder in India, aged between 1 and 13 years, is ₹0 lakhs.
What do you mean by plant breeder?
Plant breeders are genetic engineers who use various breeding techniques to improve crops. Their main objective is to improve crops, with most breeding objectives remaining similar to earlier times.

What is the study of plant genetics?
Plant genetics is the study of genes, genetic variation, and heredity in plants, a field that intersects with biology and botany, and is closely linked to the study of information systems. Gregor Mendel, a late 19th-century scientist and Augustinian friar, discovered that traits are passed down through discrete “units of inheritance” in organisms, such as pea plants. This concept forms the basis for modern plant genetics.
Plants use DNA to pass on their traits, unlike animal genetics which often focuses on parentage and lineage. Speciation is easier in plants due to their unique genetic abilities, such as being well-adapted to polyploidy. Plants also produce energy-dense carbohydrates via photosynthesis, which is achieved through chloroplasts, which possess their own DNA, providing an additional reservoir for genes and genetic diversity. This layer of genetic complexity is not found in animals.
What is plant genetics used for?
Plant genetics and biotechnology significantly contribute to agriculture and human society by creating new plant varieties and products with improved or novel characteristics.

What is the role of plant breeding?
The objective of plant breeding is to enhance crop yield, cultivate desired plants, develop disease-resistant crops, and create plants that can withstand extreme environmental stress. There are multiple methodologies within the field of plant breeding, including the process of backcrossing, whereby a desired plant is crossed with a non-desired plant that possesses additional traits.
Who studies plant genetics?
Molecular, quantitative, and population geneticists, genomicists, and plant breeders collaborate to mine genetic diversity and develop improved cultivars of globally and regionally important crops. The goal is to improve resource use efficiency, biotic and abiotic stress tolerance, and nutritional quality while addressing societal, environmental, and economic sustainability. The research focuses on evaluating novel crops for adaptability and productivity, targeting the diversification of Nebraska agriculture.
The research supports the training of both resident and distance-ed students in plant breeding and genetics, preparing them as catalysts for change in academia and industry. Modern field and greenhouse facilities, plant transformation, genomics, proteomics, and metabolomics core facilities enable the research. Various forward and reverse genetics, biotechnological and gene editing approaches, and physiological and biochemical profiling are used to understand and exploit genetic variation.
DNA sequencing allows for the measurement of millions of genetic differences and the expression levels of thousands of genes across various crops. Improved data management, analysis, and summarization are central to the research. The faculty work across UNL and the state and play key roles in the Center for Plant Science Innovation, the Nebraska Center for Biotechnology, the Nebraska Food for Health Center, the Water for Food Global Institute, and the Quantitative Life Sciences Initiative.
📹 GMOs are Nothing New: Plant Breeding & Gene Editing: Crash Course Botany #11
Humans love to play with their food—in fact, we’ve been doing it for thousands of years. In this episode of Crash Course Botany, …
Despite the interesting info on agrobacteria, selective plant breeding and gene editing are still very different methods. As she said, kale, kohlrabi, broccoli, etc are all still part of the same species. Selecting for a larger leaf or larger flower doesn’t (usually) involve gene insertion. She called them the “dog breeds” of vegetables. Well the gmo equivalent would be inserting, say, a fish gene into a dog for certain effects (and claiming legal ownership of every dog from then on which can proven to contain that fish gene). Claiming that genetic engineering is always being done to increase nutrition and production is not always true. How about when Monsanto makes soybeans resistant to the Roundup herbicide they also sell, so that fields can be drenched with it, driving up Roundup sales, while also aggressively suing every neighboring farmer that their gmo pollen drifts to for patent infringement? Is it a good idea to allow profit driven mega corporations to tinker with the food supply that took us 10,000 years to develop, creating dna contamination that can’t be undone, and giving them ownership of that food supply in the process. What could go wrong? We suggest doing an episode on the Precautionary Principle.
There’s a difference between hybridization/selective-breeding, and corporate-patented gene editing. When you hear someone who’s against GMOs, it almost always someone who is against the shady/secretive application of these sciences through places like Monsanto (the first commercially available products of which have only been around for ~30 years or so). It’s an aversion to the politics and coercion towards farmers. To perpetuate this conflation of corporate science and natural hybridization furthers Monsanto’s narrative that they’re doing nothing wrong.
We have no idea what the effect of this gene editing for “natural” pesticide is having on our food and bodies. It has also created the same problem we have with antibiotics. Nature finds a way and now these GMO crops actually require more pesticide use. It is, of course, super convenient that the same companies modifying the genes of plants also produce pesticides.
I wonder if the concerns of diversity are over stated. I think the sweet potato is a good example as to why. Working off of a point in the article. Despite being widly cultivated, we have hundreds of wild and domesticated varieties. It just seems like the unregulated natural transgenic didn’t lead to a large diversity issues. This is just a hypothesis that I need to put more thought into.
