P: Parent Plants when beginning a cross. This is more of an arbitrary designation when beginning to breed a line to identify the two plants you started your project with. This will rarely be shown in this form on most commercial seed product. Many products that do include parentage will often cite “Mother” and “Father” for parent plants.
F1: The first Filial generation. A cross of two unlike parent plants. Term used for regular breeding of a natural female and a natural male plant.
PFemale x PMale = F1
F2: The second Filial generation cross of two F1 progeny (offspring).
F1 (Female) x F1 (Male) = F2
F3: The third Filial generation cross of two F2progeny.
F2 (Female) x F2 (Male) = F3 and so on for successive generations.
IBL: Highly stable cross, typically F5 or greater, with very little genetic diversity in progeny.
R1: First generation cross of two unlike parents (same as F1) but indicates the pollen donor was female (feminized).
PFemale x PFemale Pollen Donor = R1
S1: “Selfed” Generation 1. Ultimate form of inbreeding. A feminized cross of a single plant bred into itself. This could be done with a single source plant that has some of its nodes feminized with the rest left to develop female organs naturally. The feminized branches will grow anthers and pollinate the remaining natural female organs (ovules within the pistils) producing seed that inherits its genome from a single genetic source instead of from two different genetic sources. Selfing can also be done via cloning the source plant and making either the clone or the source plant the pollen donor and the other the pollen receiver or by doing the same procedure with two clones from the exact same source plant.
P Source x P Source / P Source x P Clone / P Clone x P Clone = S1
Bx: Back cross. Label used when progeny is crossed back into one of its parents.
F1 (Female) x PMale or PFemale x F1 (Male) = Bx1 (Backcross 1)
RBx: Reverse Back cross. Same as backcross but with a female pollen donor instead of a natural male pollen donor.
F1 (Female x PFemale PollenDonor or PFemale x F1 (Female Pollen Donor) = RBx1(Reverse Backcross 1)
As told by Rick, Owner of Mosca Seeds, this is the triumphant cultivation story of their very own Root Beer Mac S1! Enjoy!
The Beginning: The Collaboration
Capulator Collaboration (2019):Mosca Seeds was collaborating with Capulator on High Chew, a combination of Indiana Bubble Gum and Mac. Bubble Gum was the first strain Cap ever grew. Capulator's influence is known for producing the infamous MAC (Miracle Alien Cookies) strain, which has become a staple in the cannabis scene, especially for its frosty, resin-drenched buds and potent effects. The decision to use MAC #11 male pollen from Capulator’s work would bring that incredible resin production and potency to the Root Beer Mac.
The Key Ingredients: Root Beer & MAC #11
Root Beer: Mean Gene of Mendocino’s Root Beer strain was a spectacular cultivar to bring into the mix. Mean Gene gifted us a pack of his Root Beer. Root Beer is known for its distinctive, sweet, and spicy aroma, resembling the soda it's named after. This unique terpene profile brings a nostalgic, flavorful touch that’s both refreshing and intoxicating. The creamy and smooth root beer notes with hints of vanilla are what made this strain a standout.
MAC #11 Male: The MAC line is renowned for its dense, trichome-rich buds and potent effects. By using pollen from the MAC #11 male, we’ve introduced a layer of resin-heavy genetics that would amplify the frosty appearance and powerful effects in the offspring. The MAC influence adds a high amount of potency, structure, and a bit of funk to the flavor, which, when combined with Root Beer, creates a truly unique combination.
The Breeding Process: Perfecting the Expression
Selection Process: After receiving the Root Beer genetics from Mean Gene and growing them out, Team Mosca selected the best two females, which is an important part of any successful breeding project. The goal was clear: to create a strain that had frosty resin-crusted buds and that special Root Beer terpene profile. We then pollinated these selected female with the MAC#11 pollen. Over the next few years, we grew out batches of the offspring and pheno-hunted keepers from every trial. We then tested the keepers against each other until we found the best of the best females.
Selfing & Backcrossing:
To create stable genetics and the best expressions, we chose to self the best female (creating an S1 generation) and backcross the most potent female to the most fragrant female(creating a Bx generation).
Selfing: This allows you to lock in the desired traits of your best female, making sure those qualities are passed down consistently in the offspring.
Backcrossing(Bx): This is another method of reinforcing certain traits by breeding the offspring back with one of the original parents. By using the most potent female and backcrossing to the most fragrant female, we ensured the strain would not only pack a punch in terms of potency but also maintain the signature root beer flavor and aroma.
The Outcome: Root Beer Mac
Frosty, Resin-Covered Buds: With the combination of the MAC #11 genetics and the Root Beer terps, the result is a strain that produces heavily resin-coated buds, perfect for both smoking and concentrate production.
Flavor Profile: The Root Beer terps stand out with that sweet, creamy, and slightly spicy flavor you’re after, delivering a refreshing and nostalgic taste. The MAC influence adds additional complexity, with hints of earthy, gassy, and funky notes, which balance out the sweetness of the Root Beer and create a unique and unforgettable flavor profile.
Potent Effects: With the powerful resin production from the MAC genetics, combined with the Root Beer’s relaxing yet uplifting effects, you’ll experience a balanced high that’s both euphoric and soothing. Whether it’s a good time to chill or you need something to help relieve stress, the high is both enjoyable and powerful. Root Beer Mac has tested at 26+ %.
Final Thoughts: A Labor of Love
This five year process of careful selection and testing really shows the dedication that went into creating Root Beer Mac. Our vision of frosty, resin-rich buds with a one-of-a-kind flavor profile has come to fruition, offering a strain that’s both refreshing and potent. Whether you're a grower or consumer, Root Beer Mac is a true standout with its complex terpenes and heavy resin production.
If you’re a fan of unique flavors and terpene profiles, this is one to try—root beer fans (and cannabis connoisseurs) will appreciate the creativity behind it. Enjoy the fruits of our labor.
