ECOLOGICAL ASSESSMENT OF MEDIUM-RATING AND MEDIUM-LATE-RATING SOYBEAN VARIETIES

Abstract

Medium-ripe soybean varieties in the State Register of Plant Varieties Suitable for Distribution in Ukraine in 2021 are represented by 31 varieties. Drought resistance of medium-ripe soybean varieties was 6–9 points. The most drought-resistant varieties were Sandina, Panonka, ES Pallador, and the least drought-resistant were Valentia, KSB 938 – 6 points each, Poltava – 7 points. The seed yield of medium-ripe soybean varieties is 18.0–34.6 c / ha. The most productive varieties were EC Pallador – 34.6 с / ha, Stein 14F06 – 34.1 с / ha, Stein 17Zh32 –33.6 с / ha, Stein 15I63, Stein 13Zh23 – 32.6 с / ha, Amphora – 32.0 c / ha. The lowest yields were Banjo KS – 18.0 c / ha, SG Ayder, Morevia – 20.0 c / ha, Irina – 20.1 c / ha, Valentia – 20.2 c / ha, Kent – 20.4 c / ha. Saidin soybean varieties had the highest protein content in seeds – 42.1%, Amphora, Stein 17Zh32 – 41.6% each, Banjo KS, SG SR Picor – 41.5% each, Stein 11X02 – 41.4%. Apollo varieties had the lowest protein content in seeds – 34.0%, Valentia – 35.7%, Masha – 36.0%, Vasylkivska – 36.1%. The highest fat content in the seeds had medium-ripe varieties of soybean Valentia – 24.3%, Vasylkivska – 23.5%, Tena – 23.4%, Apollo – 23.2%. The least fat was contained in the seeds of varieties Stein 17Zh32 – 19.9%, EC Pallador, Stein 14F06 – 20.2%. Medium-late soybean varieties in the State Register of plant varieties suitable for distribution in 2021 included only 4. The most drought-resistant variety was Svyatogor – 9 points, other varieties had a drought resistance score of 8. The most productive was soybean variety Stein 20F26 – 29.4 с / ha. The lowest yields were Svyatogor – 22.6 c / ha and Kristina – 22.7 c / ha. The highest protein content was in the seeds of Ananda – 39.7% and Christina – 39.0%, and the lowest – in the variety Svyatogor – 37.3%. The highest fat content – 22.0% had the variety Ananda, and the lowest fat content was the varieties Christina – 20.7% and Stein 20F26 – 20.9%.
