How to become a Plant Breeder in the UK
Develop the new crops, flowers and trees of tomorrow. Combine genetics, fieldwork and science to feed a growing population and improve the plants we rely on.
A plant breeder is a scientist who develops new and improved plant varieties. To become a plant breeder in the UK, you typically need a degree in plant science, biology, agriculture or genetics, followed by hands-on experience through placements, internships or research roles. Starting salaries usually sit around £20,000 to £26,000, rising to £40,000 or more with experience and specialism.
What is a plant breeder?
A plant breeder works on improving the quality and performance of existing agricultural and horticultural crops, while also developing entirely new varieties. The job blends genetics, biology and practical growing skills to create plants that yield more, taste better, resist disease or stand up to a changing climate.
Plant breeders shape what ends up on supermarket shelves, in gardens, in fields and in forests. Whether it is a wheat variety that needs less water, a tomato with a longer shelf life or a flower bred for a new colour, the work of plant breeders sits behind it all.
If you are curious about how food gets to your plate or how the plants in your local garden centre came to be, a career in plant breeding lets you be the person making those decisions.
What does a plant breeder do?
Field trials
Growing, testing and selecting new varieties in real conditions
Lab work
Genetic analysis, cross-pollination and seed development
Data & reporting
Tracking results, writing findings and meeting market needs
The day-to-day work depends on the type of crop or plant you specialise in, but most plant breeders divide their time between fieldwork, laboratory research and data analysis.
In the field, you might be running trials, hand-pollinating plants, selecting parent stock and observing how new varieties perform across seasons. In the lab, you could be examining seedlings, running DNA tests or using molecular markers to identify desirable traits. Behind the scenes, there is plenty of data work, comparing yields, logging characteristics and writing reports for growers, retailers and regulators.
Some plant breeders focus on agricultural crops like wheat, barley and potatoes. Others work on ornamentals, fruit, vegetables, trees or grasses. The work changes with the season, which keeps things varied and interesting.

Leadership positions in commercial breeding programmes can push earnings significantly higher.
How to become a plant breeder
There are several routes into plant breeding, depending on where you are starting from.
If you are at secondary school, focus on biology, chemistry and maths. Strong GCSEs in science subjects will set you up well for the next stage. Take a look at the secondary school career guidance for more on planning your route.
If you are at college or sixth form, A-Levels or T-Levels in biology, chemistry, agriculture or environmental science are the most useful. Some students also take a Level 3 Diploma in horticulture or applied science. The college and sixth form guide explains how to choose qualifications that match your goals.
If you are heading to university, look for a BSc in plant science, plant biology, agriculture, genetics, biological sciences or horticulture. Many universities offer combined degrees that let you specialise in breeding or genetics as you progress. The university route guidance explains what to expect and how to choose a course.
If you are a career changer, you do not have to start from scratch. Open University courses, postgraduate conversion degrees and specialist short courses can all open the door to a breeding career. Visit the career changer guide for advice on moving into plant science.
What qualifications do you need to be a plant breeder?
Most plant breeding roles need at least an undergraduate degree. The most relevant subjects are:
- Plant Science
- Plant Biology
- Agriculture
- Biology or Biological Sciences
- Genetics
- Horticulture
- Crop Science
A degree in a related field can also work well, such as Botany, Ecology, Environmental Science, Biotechnology or Biochemistry.
For senior research and breeding programme positions, a master’s degree (MSc) or doctorate (PhD) is usually expected. These let you specialise in areas like molecular breeding, quantitative genetics or specific crop groups.
Apprenticeships are another way in. They combine paid work with study, so you build experience while you earn. Have a look at the landscape and horticulture apprenticeships available, along with specialist courses that can support your career development.

Skills you need to be a plant breeder
The best plant breeders pair scientific knowledge with patience and a real love for plants. Useful skills include:
- A strong foundation in plant biology, genetics and crop science
- Attention to detail and a methodical, organised approach
- Strong analytical and problem-solving abilities
- Confidence with lab equipment, data tools and breeding software
- Good mathematical and statistical ability
- Clear written and verbal communication for reports and team work
- Teamwork, since most breeding programmes are collaborative
- Patience and persistence (new varieties can take years to develop)
- Practical growing skills and a willingness to work outdoors
A genuine fascination with how plants work ties everything else together.
“During the height of the growing season I focus my efforts on plant identification for members of the RHS, with an average of 4,500 enquiries per year. This comes with an extensive knowledge of wild and cultivated plants that I acquired through my work as a horticulturist.”
“In the winter, I deliver training for students and take part in research on ecosystem services of cultivated plants. This is a dynamic field that allows us to promote the beneficial use of plants for the current and upcoming challenges society faces, such as mental wellbeing, water usage and mitigating our impacts on climate change.”
