Common Triploid Seeds in Agriculture

With our release of the first cannabis triploids, growers frequently ask, what are they? Triploid seeds, which have three sets of chromosomes instead of the usual two, are widely utilized in modern agriculture to enhance crop production. These seeds are particularly valuable in the development of crops that exhibit desirable traits such as sterility, disease resistance, and increased yield. The creation and application of triploid plants have been massive in shaping the way certain crops are cultivated - and cannabis is no different. Lets take a look at other crops that utilize the technology to understand its potentials in cannabis.

What Are Triploid Organisms?

Before diving into the specific crops that utilize triploid seeds, it is important to understand what triploidy is. Triploidy occurs when a plant has three sets of chromosomes (3n) instead of the normal two (2n), which is the case in most organisms. This condition can arise naturally or be induced artificially through techniques such as the application of a compound that interferes with cell division. In plants, triploidy often results in sterility because of irregularities during meiosis, the process through which reproductive cells are formed. This sterility can be advantageous in certain crops, particularly those that are cultivated for their fruits - and with cannabis - their flowers. You can learn about the process we use for producing cannabis triploids here. But read on for a list of familiar crops you may not have known were triploids.

Seedless Fruits

One of the most well-known applications of triploid seeds is in the production of seedless fruits. Many popular fruits are produced using triploid cultivars, offering consumers a more enjoyable eating experience free from seeds. The following crops are examples of those that benefit from triploidy:

Seedless Watermelons: One of the most significant uses of triploid seeds is in the production of seedless watermelons. Watermelons are typically diploid (2n), but by crossing diploid watermelon plants with tetraploid (4n) watermelon plants, triploid (3n) offspring are produced. These triploid watermelons do not produce viable seeds, making them more convenient for consumption. The triploid nature of these plants prevents the formation of seeds by disrupting normal seed development, resulting in a smooth, seedless fruit that is preferred by consumers.
Seedless Grapes: Another common crop that uses triploid seeds is grapes, particularly those that are sold as seedless varieties. Triploid grapes are typically produced through cross-breeding between diploid and tetraploid parent plants. The resulting triploid grapes are sterile and do not form seeds. This sterility allows for the development of a desirable fruit without the inconvenience of seeds, making them more marketable and popular among consumers.
Seedless Bananas: Seedless bananas, like the ones commonly found in grocery stores, are typically triploid. The Cavendish banana, a popular variety, is a sterile triploid, with three sets of chromosomes instead of the usual two. This sterility makes bananas easier to consume and process, as the fruit does not develop seeds. The cultivation of seedless bananas is also facilitated by their triploid nature, which promotes consistency in fruit size and quality.

Improved Crops with Better Yields

While seedless fruits are the most well-known use of triploid seeds, other crops also benefit from triploidy in ways that improve yield and productivity. The following examples demonstrate the broader agricultural benefits of triploid cultivars:

Triploid Strawberries: Some varieties of strawberries are also triploid, which gives them several advantages over their diploid counterparts. Triploid strawberries tend to be larger, more robust, and more disease-resistant. These plants produce higher yields due to the extra set of chromosomes, which can result in increased cell size and fruit production. Additionally, triploid strawberries can be more resilient to environmental stress and pests.
Triploid Peppers and Tomatoes: In the development of certain hybrid crops, triploid varieties of peppers and tomatoes have been created. These triploid plants often have better resistance to disease and environmental stress, as well as higher yields. Additionally, these plants tend to have thicker skins, which may help them retain their freshness longer when transported or stored.
Triploid Hops: Known for being bigger producers, triploid hops also produce more complex aromas than diploid plants. Many triploid hop varieties are also bred to have higher alpha acid content, which is crucial for bittering in beer. This makes them more efficient for bittering purposes, allowing brewers to use fewer hops while still achieving the desired bitterness level. This can also lead to more consistent brewing outcomes.

Triploidy in Ornamental Plants

In addition to food crops, triploid seeds have also found applications in the production of ornamental plants. The triploid condition can result in ornamental flowers and plants that are larger, more visually appealing, and more durable than their diploid counterparts.

Triploid Tulips and Lilies: Some ornamental flowers, such as certain varieties of tulips and lilies, are triploid. These flowers tend to have larger blooms and more vibrant colors than their diploid relatives, making them more attractive in gardens and floral arrangements. The increased flower size and robustness are a direct result of triploidy, which helps to enhance their aesthetic appeal.

Grass Crops and Turf

Triploidy also plays a role in improving grass crops and turf for landscaping and agriculture. For instance, some varieties of grass used in turf production are triploid, which helps create a denser, more resilient lawn that is better able to withstand foot traffic and environmental stress. These triploid grasses typically show enhanced vigor, faster establishment, and improved wear tolerance.

Advantages of Triploid Crops

The use of triploid seeds offers several significant advantages in agriculture. One of the main benefits is sterility, which is desirable in seedless fruit crops and certain hybrid varieties. This sterility helps reduce the need for labor-intensive practices such as thinning or removing unwanted seeds, and it also makes the fruit more enjoyable for consumers. Additionally, triploid crops often exhibit increased size and yield, which is especially important in commercial farming where maximizing production is a key goal.

Another advantage of triploidy is disease resistance. Many triploid crops are more resistant to certain diseases and pests due to the genetic variability introduced by the extra set of chromosomes. This added genetic diversity can make triploid plants more adaptable to changing environmental conditions and less susceptible to specific pathogens.

As mentioned with hops, triploids can produce stronger and more complex aromas and terpene profiles. This allows brewers to use less material for desired flavorings and aromas.

Triploids: Not Just Big For Cannabis

From seedless watermelons and bananas to enhanced strawberries and ornamental flowers, triploid crops provide significant agricultural benefits. Cannabis is no different. As research into plant genetics continues to evolve, it is likely that the use of triploid seeds will expand further, offering even more innovations in crop production and quality.
