This article presents the results of the possibility of changing the existing scheme of primary seed production of grain crops using winter triticale as an example. It has been established that the proposed scheme has a number of advantages: firstly, it accelerates the production of original seeds; secondly, it increases the probability of preserving the variety used for seed production, and allows obtaining seeds with higher sowing and yield properties It was found that sparse seeding in accordance with the author's method involves reducing the seeding rate in the first and second year propagation nurseries to 1 million viable seeds per hectare, which ensures an increase in the propagation coefficient. It has been established that seeds obtained using the author's method make it possible to increase the yield of triticale crops by an average of 4.45 c/ha over two years. The primary seed production schemes used make it possible to obtain seeds with high sowing properties and fully complying with GOST in terms of varietal purity and germination. The author's method reduces the time required to obtain propagation nurseries by two years. During the four-year research it was established that the author's method allows for obtaining high-quality seeds of the fourth-year propagation nursery in the amount of 146,080.6 centners during this period, while using the standard scheme of primary seed production, 19,224.0 centners of seeds of the second-year propagation nursery were obtained. The increase in the number of seeds due to the use of the author's method was 126856.6, which is more than 7.6 times higher than the efficiency of the standard primary seed production scheme, while the yield properties of the seeds also differ positively.
