Improvement of technological methods of primary rice seed production

Relevance. The purpose of the research is to develop technological methods of primary seed production that ensure stable production of rice seeds to ensure import independence.

Methods. The research was conducted at the Federal State Budgetary Budgetary Institution "FNC Rice". Objects of research: seeds of three varieties of rice, selected by the Federal State Budgetary Budgetary Institution "FNC of Rice". Objects of research: rice varieties of FGBNU "FNC rice" Anita 20, Legend, Voskhod. The assessment of the seeding qualities of seeds was carried out under the conditions of laboratory experience in 2025. The sowing qualities of rice seeds were carried out in accordance with GOST 12038-84, morphological features were taken into account according to generally accepted methods. Pre-sowing treatment of rice seeds is carried out according to the recommendations and the scheme of experience.

Results. An analysis of the results showed that the use of fungicides for the pre-sowing treat­ment of rice seeds has a positive effect on crop quality, plant growth and development. An assessment of the sowing qualities of rice varieties showed that the differences may not be sig­nificant: germination varies from 97.0 to 99.0%. For all the studied variants, an increase in ger­mination energy was noted in the experiment in comparison with the control variant, since the drugs used have a high physiological activity and have a growth-stimulating effect. In the vari­ants with high sowing rates, the largest seedlings were noted (the average length is 5.7-6.5 cm), the average root length of which can reach 4.8-6.5 cm. The greatest biological effectiveness of the applied fungicides in the experiment was found in the Legend variety using the Baritone preparation (100.0%), in the Anita 20 variety using the Lomador preparation (86.7%), in the Legend variety using the Baritone variant (71.4%).
