Variety traits
Shattering is an indicator of grain resistance to falling out of the spike or inflorescence during ripening and harvesting, which influences the scale of yield losses. This trait is genetically determined and manifests under the influence of adverse weather factors.
Mentioned in descriptions 4 447 varieties reference book.
Shattering represents the ability of grain to remain attached to the spike or inflorescence during the period of standing crop over-ripening and throughout the harvesting process. The manifestation of this trait is expressed in the spontaneous dropping of grains, which directly leads to a reduction in quantitative yield indicators for the farm.
The severity of shattering depends on the morpho-anatomical structure of the plant, in particular the strength of the attachment of glumes to the rachis, the degree of development of mechanical tissues, and the diameter of vascular bundles. Furthermore, the resistance of a variety is determined by the interaction of the genotype with the environment, as sudden temperature fluctuations and squally winds can trigger losses even in relatively resistant varieties.
Resistance assessment in variety trials is conducted on a five-point scale, where 5 points correspond to high resistance and 1 point to low. In addition to visual observations, methods of manual grain 'detachment', morphological analysis of spike structure, and instrumental measurement of grain retention force or counting of fallen seeds per unit area are employed.
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.
