If you want to get in touch directly, feel free to reach out to us, and we will be happy to help you find your way.
At Better3Fruit, variety trials are a central part of how we bring new apple and pear cultivars from the breeding program to commercial reality. With over 30,000 new selections under evaluation at any given time, we rely on a global network of growers and partners to test promising candidates in real-world conditions. This article answers the most common questions about variety trials so you know exactly what to expect.
What is a variety trial in fruit breeding?
A variety trial in fruit breeding is a structured, multi-year evaluation in which a new cultivar is grown under real orchard conditions to assess its performance across a range of traits. These trials test everything from fruit quality and taste to disease tolerance, yield, and storability before a variety is considered for commercial release.
In apple and pear breeding, a variety trial is not a single experiment but a staged process. Early-stage selections are first evaluated internally; then promising candidates move into external trials, where growers plant small test blocks in different climates, soil types, and growing systems. The goal is to understand how a variety behaves outside the controlled environment of a breeding station. Only varieties that consistently perform well across multiple locations and seasons earn the right to progress toward commercial licensing.
Variety trials are distinct from simple observation plots. They follow defined protocols, collect standardised data, and compare new selections against established benchmark varieties. This rigour is what makes trial results meaningful and trustworthy for the entire fruit industry.
Why do variety trials matter for growers and the industry?
Variety trials matter because they protect growers, retailers, and consumers from investing in varieties that underperform. Without systematic field testing, a cultivar that looks promising in a breeding nursery could fail commercially due to poor storability, inconsistent colour development, or unexpected susceptibility to local diseases.
For growers specifically, planting a new apple variety represents a long-term commitment. Apple trees take several years to reach full production, meaning a poor variety choice can cost years of lost income. Variety trials reduce that risk by generating honest, location-specific performance data before large-scale planting decisions are made.
For the broader industry, trials serve as a quality filter. They ensure that only varieties with genuine commercial potential reach the market, which protects the reputation of retailers and the satisfaction of consumers. At Better3Fruit, our breeding goals focus on taste, texture, disease tolerance, and grower yield, and variety trials are the mechanism that confirms whether a new selection truly delivers on those goals in the field.
How does a variety trial actually work?
A variety trial works by planting a defined number of trees of a new selection in a commercial or semi-commercial orchard setting, then collecting structured data on fruit quality, tree health, and productivity over multiple growing seasons. Results are compared against control varieties to determine whether the new cultivar offers a genuine improvement.
The stages of a typical variety trial
Trials generally progress through several distinct phases. In the early stage, small numbers of trees are planted at a limited number of locations to gather initial impressions. If those results are encouraging, the trial expands to more sites across different regions and climates. This broader phase tests whether the variety performs consistently or whether its strengths are tied to specific conditions.
What data gets collected?
Trial participants typically record a standardised set of observations each season. These commonly include:
- Fruit size, colour, and visual appearance
- Taste and texture assessments at harvest and after storage
- Yield per tree and overall productivity
- Disease and pest incidence in the orchard
- Storability and post-harvest quality
- Tree vigour and overall management requirements
This data feeds back into our evaluation process, helping us decide whether a variety advances, requires further observation, or is discontinued. The combination of molecular marker tools used during early breeding stages and real-world trial data gives us a comprehensive picture of each candidate.
Who can participate in a variety trial?
Variety trial participants are typically professional fruit growers, nurseries, packing houses, or research stations with the capacity to plant, manage, and observe a defined number of trees according to a set protocol. Participants need access to suitable land, basic orchard infrastructure, and the ability to collect and report data reliably each season.
Because Better3Fruit operates as an independent breeding company with no preferred partners, we are genuinely open to working with growers and industry professionals from anywhere in the world. What matters most is that a potential trial partner has the right growing conditions for the variety in question, a professional approach to orchard management, and a genuine interest in contributing useful, honest data. Prior experience with new variety introductions is a strong advantage, but it is not always a strict requirement.
Research institutes and agricultural universities also make valuable trial partners, particularly for varieties for which we want to gather more controlled scientific data alongside commercial observations. If you are unsure whether your situation fits, the best approach is simply to ask us directly.
How do you apply to join a variety trial?
To apply for a variety trial with Better3Fruit, you contact us directly to express your interest, describe your growing operation, and identify which varieties or breeding goals align with your situation. There is no formal public application form; the process begins with a conversation.
When you reach out, it helps to have a clear picture of what you can offer as a trial partner. Useful information to share includes your location and climate zone, the size and type of your orchard, your experience with apple or pear production, and any specific variety traits you are most interested in evaluating. This helps us match your capabilities to the right candidate variety.
From there, if there is a good fit, we will discuss the trial protocol, the number of trees involved, the data collection requirements, and the terms of participation. We aim to make the process straightforward and collaborative because a well-run trial benefits both sides. You can explore our current apple and pear varieties to get a sense of the portfolio before starting that conversation.
What happens after a successful variety trial?
After a variety trial produces consistently strong results, the variety moves toward commercial release. This typically means it receives plant variety protection or patent rights, a commercial brand name is developed, and licensing agreements are established with growers and marketing partners who will bring the variety to market at scale.
For trial participants, a successful outcome can lead to a preferred position as an early commercial grower of the new variety. Because we carefully select the right partners for each variety to build critical mass and develop a coherent market, growers who have contributed meaningfully to a trial are often well placed for those conversations. The relationship built during the trial phase is genuinely valuable.
Not every trial ends in a commercial release, and that is by design. Our breeding program evaluates thousands of selections precisely so that only the strongest candidates reach consumers. When a variety does make it through, growers, retailers, and consumers can trust that it has earned its place. If you are ready to explore what participating in a trial could mean for your operation, get in touch with us, and let us start the conversation together.
Frequently Asked Questions
How long does a variety trial typically last before a decision is made?
Variety trials for apples and pears generally span a minimum of 3 to 5 years, and sometimes longer, because perennial fruit crops require multiple seasons of data to draw reliable conclusions. Factors like alternate bearing, climate variation from year to year, and post-harvest storability all need to be observed across several cycles. In practice, a variety may move through early internal evaluation, then external trials, before a final commercial release decision is made — a journey that can take a decade or more from initial selection to supermarket shelf.
What are the most common reasons a promising variety gets discontinued during a trial?
The most frequent reasons a variety is discontinued include inconsistent performance across different growing locations, poor storability that limits its commercial shelf life, or the emergence of disease susceptibilities that only become apparent under real orchard conditions. A variety may also be discontinued if it fails to outperform existing benchmark cultivars in a meaningful way, since the market needs a clear reason to adopt something new. This is precisely why rigorous multi-site, multi-season testing is so valuable — it surfaces these issues before growers make large-scale planting commitments.
Do trial participants receive the trees for free, or is there a cost involved?
The commercial arrangements for trial participation vary depending on the variety, the stage of the trial, and the nature of the partnership being established. In many cases, trial trees are provided at no cost or at a subsidised rate in exchange for the grower's commitment to follow the trial protocol and provide reliable data. The best approach is to raise this question directly during your initial conversation with Better3Fruit, as terms are discussed and agreed on a case-by-case basis to ensure the arrangement works fairly for both parties.
Can a small or hobby grower participate in a variety trial, or is it only for large commercial operations?
Variety trials are primarily designed for professional growers who can manage trees consistently, follow a structured data collection protocol, and maintain the orchard to a commercial standard over multiple seasons. While scale is not the only factor, a minimum level of orchard infrastructure and management expertise is necessary to generate data that is meaningful and comparable across trial sites. If you are a smaller operation with professional experience and suitable growing conditions, it is still worth reaching out to discuss whether a fit exists — Better3Fruit evaluates each potential partner on their individual merits.
What intellectual property rights apply to varieties I grow as part of a trial?
Trial trees are provided under specific trial agreements that define how the variety may be propagated, shared, and discussed during the evaluation period. Participants do not acquire any right to propagate or commercially distribute the variety simply by participating in a trial — intellectual property rights remain with the breeder until formal licensing agreements are in place. These terms are clearly outlined before any trees are planted, so it is important to review and understand the trial agreement thoroughly at the outset of the partnership.
How does climate and growing region affect whether my trial results will be useful?
Climate and growing region are actually among the most valuable variables a multi-site trial is designed to capture. A variety that excels in a cool maritime climate may perform very differently in a continental or semi-arid region, and understanding that range of behaviour is essential before commercial release. When you contact Better3Fruit about trial participation, sharing detailed information about your climate zone, typical seasonal conditions, and any local disease pressures will help determine which candidate varieties are the best match for your site — and ensure your data contributes meaningfully to the broader evaluation.
If a variety I trialled is released commercially, am I guaranteed a licence to grow it?
While trial participation puts you in a strong position for early commercial licensing conversations, it does not automatically guarantee a licence. Commercial release involves carefully selecting the right grower partners to build market volume in a coordinated way, and factors such as your region, production capacity, and alignment with the variety's target market all play a role. That said, growers who have contributed honest, high-quality trial data and built a solid working relationship with Better3Fruit are genuinely well-placed when those licensing discussions begin.
