Inflorescence

An inflorescence is a generative plant organ that determines yield architecture, pollination type, and the potential productivity of a variety. During variety testing, it serves as an important morphological marker for assessing distinctness, uniformity, stability, and agricultural value.

Mentioned in descriptions 21 881 varieties reference book.

An inflorescence is the organ where flowers, and subsequently fruits and seeds, are formed. In agronomy, the inflorescence type, the number of flowers within it, as well as its compactness and positioning, are key traits determining a plant's potential productivity and its suitability for mechanical harvesting.

During official variety trials, the inflorescence is assessed using morphometric and visual examination methods to determine compliance with DUS criteria. Parameters are recorded as numerical values of axis length, number of flowers, branches or fruits, or by using a scoring scale reflecting compactness and other significant characteristics.

Inflorescence indices depend on both the variety's genetics and environmental conditions, including agronomic practices and weather conditions during the differentiation of the primordial inflorescence. The final assessment is conducted by comparing against a standard accepted for a specific crop in a given zone, taking into account not only the number of inflorescences themselves but also the actual seed set.
