Variety traits
Plant height is a key varietal trait that determines lodging resistance, suitability for mechanical harvesting, and potential yield. This indicator is genetically determined but manifests depending on environmental conditions and agronomic practices.
Mentioned in descriptions 20 560 varieties reference book.
Plant or bush height is a varietal parameter manifested as the physical size of the stem from the soil surface to its apex or the point of inflorescence attachment. In practice, this trait determines the resistance of crops to lodging under the influence of wind and precipitation, and also dictates technological cultivation requirements, such as the need for trellising, pruning, or the use of specific planting patterns.
Plant height depends on the genetic characteristics of the variety; however, it varies significantly under the influence of external factors, including soil fertility, nitrogen application rates, plant density, as well as weather conditions and the presence of stressors such as diseases and pests. Intensive short-stature varieties often possess a higher harvest index, which positively affects crop productivity.
Evaluation of height is conducted within the framework of variety trials according to regulated methodologies by measuring with a ruler during strictly defined crop development phases, for example, during heading, flowering, or before harvest. When analyzing varieties, consideration is given not only to the mean value in centimeters but also to the stability of the trait across different years, expressed through a coefficient of variation, which indicates the degree of genotype influence on plant development.
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.
