Climate change is reshaping agriculture across the globe, and apple growing is no exception. Shifts in temperature, rainfall patterns, and seasonal timing are forcing growers and breeders to rethink which apple varieties belong in their orchards. If you would like to explore the varieties we have developed with these challenges in mind, feel free to get in touch with us, and we will be happy to help.
At Better3Fruit, we have been breeding apple and pear varieties for over two decades, and climate resilience has become one of our primary long-term goals. Understanding how a changing climate affects variety selection is essential for any grower looking to protect their business and maintain fruit quality well into the future.
How is climate change affecting apple growing conditions?
Climate change is altering apple growing conditions by disrupting the temperature patterns, water availability, and seasonal timing that orchards depend on. Warmer winters reduce the chilling hours many varieties need to break dormancy properly. Unpredictable frosts arrive later in spring, threatening blossom and early fruit development. Prolonged heat waves during summer stress trees and reduce fruit quality.
Beyond temperature, rainfall patterns are becoming less predictable. Some regions experience extended droughts, while others face intense rainfall events that increase fungal disease pressure. Both extremes create new challenges for growers who have historically relied on stable regional climates to guide their variety choices. The cumulative effect is that varieties that performed reliably for decades may no longer be the best fit for the same location.
What traits make an apple variety climate resilient?
A climate-resilient apple variety combines low chilling requirements, tolerance to heat stress, resistance to key diseases, and the ability to maintain fruit quality across variable growing conditions. No single trait defines resilience; it is a combination of characteristics that allows a variety to perform consistently even when conditions deviate from the historical norm.
Disease tolerance is particularly important as a warming, wetter climate expands the range and intensity of fungal pathogens such as scab and mildew. Varieties that carry natural resistance reduce the need for chemical intervention, which benefits both sustainability and grower economics. Alongside disease tolerance, traits such as efficient water use, stable skin finish under heat, and reliable colour development without extreme temperature swings are becoming increasingly valuable selection criteria.
How do apple breeders develop climate-resilient varieties?
Apple breeders develop climate-resilient varieties by crossing parent plants that carry desirable traits and then rigorously selecting offspring over multiple generations. Modern breeding programs use molecular markers to identify which seedlings carry the genetic building blocks for disease resistance, heat tolerance, and other target traits at an early stage, dramatically accelerating the selection process.
At Better3Fruit, we evaluate more than 10,000 new variety selections every year, with over 30,000 under evaluation at any given time. This scale allows us to cast a wide net and identify the rare combinations in which climate resilience, taste, texture, appearance, and commercial performance all come together. Manual pollination and multi-stage field evaluation ensure that only varieties meeting strict standards across all these dimensions progress toward commercial release. The result is a pipeline of varieties built not just for today’s conditions but for the growing seasons that lie ahead.
Which apple varieties perform best in a changing climate?
Apple varieties that perform best in a changing climate tend to combine strong disease resistance with broad climatic adaptability, reliable productivity, and consistent fruit quality under variable conditions. Rather than a single answer, performance depends on the specific challenges a region faces, whether that is reduced winter chilling, increased disease pressure, or summer heat stress.
Our commercial portfolio reflects this thinking. Varieties like Morgana® and Giga® have been developed with modern breeding goals that include sustainability and resilience alongside the taste and appearance traits that drive consumer demand. You can explore the full range of apple and pear varieties we have developed to find options suited to your growing region and market. The key principle is that climate-adapted varieties should not require growers to compromise on fruit quality or commercial value.
Should growers switch apple varieties because of climate change?
Growers should seriously evaluate their current variety mix in light of changing conditions, but switching varieties is a long-term investment that requires careful planning rather than reactive decision-making. Established orchards represent significant capital, and replanting carries both cost and time before a new variety reaches full production. That said, delaying the conversation carries its own risks.
The practical approach is to begin trialling climate-adapted varieties alongside existing plantings. This allows growers to gather real performance data from their specific site before committing to large-scale change. Growers should also consider market positioning: climate-resilient varieties often carry lower input costs and stronger sustainability credentials, both of which are increasingly important to retailers and consumers. Working with a breeding company that has no preferred commercial partners means growers can access the best-suited variety for their situation rather than being steered towards a particular commercial arrangement.
What does the future of apple variety selection look like?
The future of apple variety selection will be driven by the intersection of climate resilience, consumer preference, and sustainable production. Breeders, growers, and the wider food industry will need to work more closely together to ensure that new varieties reach the market with the supply chain infrastructure, quality standards, and consumer recognition needed to succeed.
Molecular breeding tools will continue to accelerate the development of varieties that carry multiple layers of disease resistance alongside strong eating quality and grower performance. Climate modelling will increasingly inform which traits breeders prioritise for specific regions. At Better3Fruit, our independence as a privately funded company means we can set our own research agenda and respond to these long-term challenges without commercial pressure to favour short-term outcomes. The varieties entering our fields today are being selected with the orchards of 2040 in mind.
Variety selection has always been one of the most consequential decisions a grower makes, and climate change has raised the stakes considerably.

Frequently Asked Questions
How many chilling hours do climate-resilient apple varieties typically require, and how do I know if my region is at risk?
Most traditional apple varieties require between 800 and 1,200 chilling hours (hours below 7°C) to break dormancy reliably, while climate-resilient varieties are being developed to perform well with significantly fewer — sometimes under 400 hours. To assess your risk, track your orchard's annual chilling hour accumulation over the past 5–10 years and compare it against the requirements of your current varieties. If you are already seeing irregular budbreak, poor fruit set, or reduced yields, your chilling hours may already be falling short. Consulting regional climate data or speaking with a specialist breeder can help you determine whether a variety reassessment is warranted.
What is the best way to start trialling new climate-adapted apple varieties without disrupting my existing orchard operation?
The most practical approach is to dedicate a small, clearly defined block — typically 0.5 to 2 hectares — to trial plantings, choosing a site that is representative of your broader orchard conditions in terms of soil type, aspect, and microclimate. Run the trial varieties alongside your current plantings for at least three to five seasons to capture meaningful performance data across different weather years. Keep detailed records of disease incidence, fruit quality metrics, labour inputs, and yield so you can make evidence-based decisions before committing to larger-scale replanting. Partnering directly with a breeding company gives you access to technical support and variety-specific guidance throughout the trial period.
Can climate-resilient apple varieties really match the taste and appearance standards that retailers and consumers expect?
Yes — modern breeding programs specifically select for taste, texture, skin finish, and colour alongside resilience traits, meaning growers no longer have to choose between performance and quality. Early-generation disease-resistant varieties sometimes carried trade-offs in eating quality, but advances in molecular breeding and the scale of current selection programs mean those compromises are increasingly a thing of the past. Varieties like Morgana® and Giga® are examples of how commercial-grade appearance and eating quality can be achieved within a resilience-focused breeding framework. Retailers are also becoming more receptive to varieties that carry strong sustainability credentials, which can open new market opportunities rather than limiting them.
How does increased disease pressure from climate change affect a grower's input costs, and how much can resistant varieties help?
Warmer, wetter conditions expand both the geographic range and the seasonal window of fungal pathogens like apple scab (Venturia inaequalis) and powdery mildew, which can significantly increase the number of spray applications required each season — adding both direct chemical costs and labour. Varieties carrying strong natural disease resistance can reduce fungicide programme intensity considerably, with some growers reporting reductions of 50–80% in spray inputs depending on the pathogen and local disease pressure. Beyond cost savings, reduced chemical use strengthens a grower's sustainability profile, which is increasingly relevant for retailer certification schemes and consumer-facing marketing. Over the lifetime of an orchard planting, the cumulative savings from lower input costs can substantially offset the investment in transitioning to resistant varieties.
What common mistakes do growers make when selecting apple varieties in response to climate change?
One of the most common mistakes is reacting too quickly to a single bad season — selecting a new variety based on one year of unusual weather rather than a clear long-term trend in local climate data. Equally, some growers focus narrowly on a single resilience trait, such as low chilling requirement, without evaluating how a variety performs across the full range of challenges their region faces, including disease pressure, heat stress, and market fit. Another frequent pitfall is choosing varieties without considering the commercial infrastructure needed to support them — variety success depends not just on orchard performance but on having access to the right rootstocks, storage protocols, and market channels. Working with an independent breeder who can assess your full situation, rather than a partner with a commercial interest in a specific variety, helps avoid these traps.
How far in advance should growers be planning variety transitions to stay ahead of climate change impacts?
Given that apple orchards typically take three to five years to reach meaningful production after planting and are expected to remain productive for 15–25 years, growers should be making variety decisions today with the climate conditions of the 2040s in mind. This means using regional climate projections — available through national meteorological services and agricultural research institutes — to anticipate how chilling hours, frost timing, and disease pressure are likely to shift over the lifespan of a new planting. The orchards being planted in the next two to three years will be producing fruit well into a period when climate impacts are projected to be considerably more pronounced than they are today. Starting the conversation with breeders and advisors now, rather than waiting for problems to become acute, is the most cost-effective strategy.
Does working with an independent breeding company make a difference when selecting climate-adapted varieties?
It can make a significant practical difference. Breeding companies that are independent and privately funded are not tied to preferred commercial partners, specific retail programmes, or proprietary supply chains, which means their variety recommendations are guided by what genuinely suits a grower's agronomic situation and target market rather than by commercial incentives. This independence also allows long-term research agendas to be set around genuine breeding priorities — such as multi-decade climate resilience — rather than short-term commercial pressures. For growers evaluating varieties for a 20-year orchard investment, having access to unbiased, science-led guidance is a meaningful advantage in making the right long-term decision.
