PRIMARY SEED PRODUCTION OF A NEW WINTER WHEAT VARIETY SKIPETR 2, BREEDING BY THE FEDERAL SCIENTIFIC CENTER OF LEGUMES AND GROAT CROPS

The article presents data on the organization of primary seed production of the new winter wheat variety Skipetr 2. The concept of "primary seed production" is considered, which is based on the individual-family method of selection with a two-year evaluation of the offspring, allowing to preserve and evaluate the variety by the most important economic and biological characteristics and properties. The importance of using quality seeds in preserving the variety is emphasized.It was found that field and laboratory rejection in the nursery testing the first year offspring varied in the range from 20.0 to 37.8%, and in the nursery testing the second year offspring varied from 13.6 to 1.66%. It was found that the highest yield (82 c/ha) was formed in 2022, and the largest weight of 1000 seeds (51 g) was obtained in 2023. It was revealed that the seed material, according to the main sowing and varietal indicators (seed purity, moisture, germination energy and germination), met the requirements of GOST 52325-2005.The obtained results confirm the compliance of the seeds with the requirements of state standards and their potential for mass production and use in agribusiness.
