Papaya has established itself as one of the most appealing tropical fruits for consumers: it stands out for its sweet flavour, juicy texture and nutritional profile. But behind a good papaya lie not only climate and agronomic management, but also genetics, adaptation to the growing system and the right choice of variety.

At CapGen Seeds, we work on developing papaya seeds tailored to the real needs of farmers and the market. Our Papaya Nostrum range comprises materials adapted to greenhouse cultivation, with manageable plants, uniform fruit and a commercial quality designed to meet the demands of growers, distributors and consumers.

Why papaya is gaining prominence in the market

Papaya is a tropical fruit that is increasingly valued for its versatility. It can be eaten fresh, in juices, salads, desserts or culinary dishes, and meets a growing demand for exotic, healthy and distinctive fruits.

From a nutritional perspective, papaya is recognised for its vitamin C content, fibre and naturally occurring compounds. It also contains papain, a proteolytic enzyme unique to papaya that aids in the breakdown of proteins and is also used in the food industry, for example, as a natural meat tenderiser.

For the horticultural sector, the benefits extend beyond the end consumer. Papaya can be a high-value alternative when grown using suitable planting materials, with appropriate technical management and a clearly defined commercial market. In this context, growing papaya in greenhouses allows for better environmental control, protects the plant from adverse conditions and leads to more consistent production.

Three interesting facts about papaya

1. A tropical fruit with great culinary value

Papaya is notable for its balance of sweetness, aroma and texture. It is most commonly eaten fresh, although it is also used in savoury dishes, smoothies, desserts and health-conscious recipes.

2. A plant that looks like a tree but is herbaceous in nature

Although its appearance may be reminiscent of a small tree, the papaya has a non-woody stem and a very distinctive plant structure. This characteristic influences its management and highlights the importance of selecting plants of a suitable size for each production system.

3. Papain, a highly valued enzyme

Papain is one of the best-known characteristics of papaya. This enzyme is found in various parts of the plant and has been used in food applications due to its ability to act on proteins.

Genetics: key to greenhouse papaya cultivation

To produce a high-quality papaya, the choice of seed is crucial. Growers need plants that are well-suited to the growing environment, perform well in greenhouses, are easy to manage, are productive, and produce fruit that meets market demand.

At CapGen Seeds, our papaya lines have been developed with protected cultivation and current production conditions in mind. Among our most notable solutions under the Papaya Nostrum range are Papaya Alicia and Papaya Caballero, two varieties with distinct characteristics tailored to different commercial objectives.

Alicia Papaya: size, adaptability and quality

Alicia is a papaya variety designed for growers seeking a manageable plant that performs well in greenhouses and produces larger fruit.

The plant has a very low growth habit, balanced foliage and short internodes, which makes it easier to manage within the greenhouse. It also stands out for its good cold tolerance, a useful characteristic for maintaining yield potential during periods of lower temperatures.

In terms of fruit, Alicia produces fruits weighing between 750 and 1,100 grams. It allows harvesting at an advanced stage of ripeness, promoting good internal quality and a more satisfying eating experience.

Papaya Caballero: dwarf variety, uniformity and high sweetness

Papaya Caballero is a particularly attractive option for farms seeking to optimise available space and grow a compact plant suited to lower-height structures.

Its very low, almost dwarf-like growth habit makes it well-suited to low-ceilinged greenhouses. Thanks to its medium-to-low foliage, it allows planting density to be increased by up to 10 per cent, helping to improve the utilisation of the cultivated area.

As for the fruit, Caballero stands out for its uniform shape and a commercial size of between 650 and 900 grams. Its soluble solids content, at around 14–15° Brix, makes it a papaya of great interest to markets that particularly value sweet flavour and organoleptic quality.
