ACHIEVEMENTS AND PROSPECTS OF YELLOW LUPINE BREEDING IN THE CONDITIONS OF POLISSIA OF UKRAINE

Abstract

Yellow lupine Lupinusluteus is a culture of light sandy and sandy soils. The Volyn DSGDS of the ISG of the Carpathian region of the National Academy of Sciences is located in the Western Polissia zone of Ukraine, where light sandy and sandy soils prevail, which is best suited for growing yellow fodder lupine. For more than 60 years, the Volyn Agricultural Research Station has been dealing with issues of selection and seed production of yellow fodder lupine. Scientific work continues to this day. The collection of the culture’s gene pool, as well as its own breeding material, was used as the starting material for the creation of lupine varieties. In all nurseries and variety tests, the Svityaz variety is accepted as the standard. 82 numbers were studied in the nursery of the competitive variety test for the years 2016–2020. In the competition nursery, the seeds of the best numbers, which were selected in the control and preliminary variety tests, were sown. The standard – the Svityaz variety – was sown every 5 numbers. Alkaloid analysis was carried out – no alkaloid plants were found. In terms of grain yield of the studied genotypes, on average over the reporting years, the standard variety with a yield of 1.98 t/ha exceeded almost all numbers, except for hybrid combinations under field numbers 45 and 48, where the yield was close to the standard grain yield (+0.10, +0.01 t/ha respectively). The average grain yield in the nursery was 1.85 t/ha. The height of the plants ranged from 54.2 to 57.7 cm. As a result of the phytopathological evaluation in the competitive nursery for resistance to Fusarium wilt and viral narrow-leaved. The breeding work of the Volyn DSGDS ISG of the Carpathian region of the National Academy of Sciences is aimed at creating varieties that would give a significant increase in grain and green mass and be resistant to major diseases and the introduction into production of new domestic high-yielding varieties of yellow lupine adapted to the conditions of the Western Polissia of Ukraine. In 2021, the yellow lupine variety – DarunokPolissya was entered into the State Register of Plant Varieties of Ukraine. Botanical taxon Lupinusluteus Species maculatus. A variety of grain and fodder direction.
