Variety traits
Abundance and duration of flowering are phenological indicators reflecting the density of flowers on a plant and the time span of the flowering phase, which determine the potential productivity and adaptability of a variety.
Mentioned in descriptions 4 764 varieties reference book.
Duration of flowering characterizes the period in days during which the plant is in this phase, defining the crop's window of vulnerability to external factors. Abundance of flowering represents the quantitative or visual density of flowers on a plant, serving as an indicator of reproductive capacity and potential yield.
During variety testing, evaluation is carried out based on phenological dates, including the onset, peak, and end of flowering, as well as by using scoring scales. High scores are assigned to varieties with synchronous and uniform flowering without abnormalities, whereas low values indicate weak or uneven plant development.
These indicators are determined by the genetic characteristics of the variety, as well as by the influence of photoperiodism, temperature regime, and moisture availability. Flowering stability is evaluated by comparing with regionalized standard varieties, with deviations in timing of more than five days being considered significant for determining the maturity group.
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.
