Перспективные сортообразцы козлятника восточного в Северо-Западном регионе РФ

Abstract

По урожайности зелёной массы сортообразец F6 превысил контроль на 40%, а по сбору сырого протеина — на 45%. По урожайности зелёной массы сортообразец F6 превысил контроль на 40%, а по сбору сырого протеина — на 45%. Bioclimatic potential of the Pskov region provides high-quality seeds of almost all species of gramineous and some species of legumes. The primary role in forage production belongs to sown grasses both in fields (182.8 thousand hectares) and in grasslands (natural hayfields (230 thousand hectares) and pastures (244 thousand hectares). New varieties of perennial grasses cultivated using modern practices are promising means to increase yield and quality of forage resources. Breeding new varieties of eastern goat’s rue was carried out during 2018–2021 at the nurseries of the Federal Research Center of Fibre Crops. The test nursery was established in 2018 using promising genotypes selected earlier in the intercross nursery (F6, F7 и F8) and clone nursery (26-2-8, 27-1-14 and 27-2-15). The variety “Yubilyar” (the Pskov Agricultural Research Institute) performed as the standard. The test nursery selected genotypes having the number of valuable morphological and economically-important traits. Genotypes were evaluated according to their morphology, green mass and seed productivity as well as forage quality. Such genotypes as F6, F7 and F8 stood out due to their height, seed productivity, forage mass yield and quality. Genotype F6 exceeded the standard by 40% in green mass yield and 45% — in crude protein content.
