University of California, Davis: Fig variety strains with the UCD heritage often contain the UCD suffix, (e.g. Black Maidera UCD).

UCR (University of California, Riverside) is a renowned research institution with a significant breeding program for figs and other crops. Fig varieties developed through the UCR breeding program are labeled with the UCR prefix, indicating their origin. These varieties are often the result of extensive research and cultivation efforts aimed at improving traits like fruit quality, yield, and disease resistance.

For example, the variety UCR 278-128, also known as Golden Riverside, showcases the innovative work of the program. UCR figs are highly valued among collectors and growers for their unique characteristics and adaptability, making them a staple in both research and home gardening circles.

Unifera refers to fig varieties that produce only a single crop per year, unlike types that have dual crops (like breba and main crops). In unifera figs, all fruit is produced on the current season's growth and typically matures later in the growing season.

These figs are popular for their simplicity and reliability, as they don’t require the complicated pollination processes needed for dual-cropping varieties. For collectors, unifera figs are valued for their consistent fruiting patterns and ease of cultivation.

Unknown (aka U. or Unk.) is a designation used to describe fig varieties with uncertain or unidentified origins. This label is often applied to varieties that are previously undocumented or do not match the characteristics of the variety they were initially labeled as.

Figs marked as "Unknown" are typically evaluated by collectors and growers for unique traits and potential value. While their history may be unclear, they often contribute to the diversity and intrigue of fig cultivation, providing opportunities for discovery and study within the fig-growing community.

Up-pot (or Up-potting) refers to the process of transplanting a plant into a larger container to accommodate its growing root system. This practice allows the plant to thrive by providing more space for roots to expand, promoting healthier growth and preventing the plant from becoming root-bound.

Up-potting is a common step in container gardening and is essential for maintaining vigorous plants, especially as they mature or outgrow their current pots.

United States Department of Agriculture: Also known as the Agriculture Department, is the U.S. federal executive department responsible for developing and executing federal laws related to farming, forestry, rural economic development, and food. It aims to meet the needs of farmers and ranchers, promote agricultural trade and production, work to assure food safety, protect natural resources, foster rural communities and end hunger in the United States and internationally.
