The Yasmina variety is a new, highly productive spring fodder barley. It was created at the Institute of Agriculture in Karnobat by means of a combinatorial selection method. The biological and economic traits of the variety were tested in the Institute's competitive variety trials and the IASAS system during 2019-2020. The aim of this study was to present the biological and economic traits of the new recognized spring six-row barley variety Yasmina. In the ecological network regions, it demonstrated high productivity. The mean yield from the new variety obtained in 4 Bulgarian regions was proven higher than the one from the standard variety Venera by 22.0%. During the testing period, the variety realized a yield of up to 6500 kg/a. With high protein content of 13.51%, it is ideally suited for fodder.The variety has good lodging resistance. Yasmina was recognized as an original cultivar with Order No RD-12-4/10 Mar 2021 by the Minister of Agriculture, Food and Forestry and was approved for entry in List A of the Official Variety List of the Republic of Bulgaria.

Five winter feed barley varieties were tested at the experimental field of the Institute of Agriculture-Kamobat over a six-year period to assess their yield potential and stability. Varieties Bozhin and Iz Bori are new varieties and Vesletc, Izgrev and Aheloj 2 are widely grown feed barley varieties in Bulgaria. Stability parameters were estimated by the model of Lin and Binns (1988) and G GE biplot methodology was used for graphical display of yield data. According to the results, genotype x environment interactions for grain yield was highly significant indicating genetic variability between genotypes by changing environment. Average grain yield of varieties in six-year trail ranged from 5.13 t/ha (Vesletc) to 5. 78 t/ha (Bozhin). High yield combined with high stability was demonstrated by new varieties Bozhin end Iz Bori. [ABSTRACT FROM AUTHOR]
