New sources of higher green matter quality for perennial grasses in the southern forest-steppe environments of West Siberia by O. A. Yusova

“…High responsiveness to improved environmental conditions and high stability (bi &gt; 1, σ2 d &lt; 1) were observed in the alfalfa cultivars ‘Omsky 7’, ‘Elbrus’ (protein content); ‘Flora 5’ and ‘Flora 6’ (protein content, feed value units, and green matter yield), and the bromegrass cultivars ‘SibNIISKhoz 99’ (protein content, feed value units, and green matter yield) and ‘Titan’ (feed values units). …”
