The Diapason variety was submitted for variety trials, but it is listed as rejected or delisted in a number of national descriptive lists. This status is due to the fact that the variety did not demonstrate significant improvements in agrotechnical indicators or grain quality compared to existing standards.
Due to the variety's exclusion from lists of promising varieties, detailed agronomic characteristics, such as disease resistance indicators, plant height, or precise grain quality parameters, are absent from open sources.
