Variety traits
Budding in variety testing is a phenological plant development stage characterized by the formation of flower primordia, used to determine the maturity group of a variety.
Mentioned in descriptions 5 860 varieties reference book.
Budding is a development stage during which flower primordia are formed in a plant. In state variety testing protocols, the dates of the onset and full budding stage are recorded, which is visually determined when the trait appears in 75% of plants on the trial plot.
Data on the timing of this stage allows for the classification of varieties by maturity into early-maturing, mid-maturing, and late-maturing. The evaluation of the duration of the period from emergence to budding depends on the climatic conditions of the region and helps the agronomist select varieties capable of escaping drought or late frosts.
An important qualitative indicator of a variety is its resistance to bud shedding, which allows for reducing crop losses. When selecting a variety, it is necessary to distinguish between the phenological development stage and commercial names of growth regulators, as the use of the latter is an agrotechnical practice rather than an inherited trait of the plant.
Selection based on the description text, not official resistance ratings: such data is not available in registers. Mention indicates that the trait is discussed in the variety's sources; see the variety's profile for details on what is specifically stated.
