Methods of biotechnology are used to enhance the efficiency of spring barley (Hordeum vulgare L.) breeding. Anther culture method has been used for the production of spring barley DH lines at the Lithuanian Institute of Agriculture (LIA) since 1996. Androgenic plants were produced from the spring barley genotypes of Lithuanian origin. In 1998-2000 at the LIA, grain yield and other agronomic traits in spring barley DH lines, produced by anther culture, were evaluated. After three years evaluation, 4 DH lines notable for agronomic valuable traits were selected for breeding purposes. The spring barley DH lines 7533-26, 7456-39, 7456-33, 7456-46 were distinguished by a short straw, satisfactory tillering, good lodging resistance, high yield, 1000 kernel weight, spike length, high grain number per spike and high grain weight per spike. Those 4 DH lines will be included in the competitive yield trials and the spring barley breeding program. Also, DH lines 7533-26, 7456-39, 7456-33, and 7456-46 will be passed on to long-term seed storage in the Lithuanian Genebank. Variability of the examined traits in spring barley DH lines was established on the basis of analysis. The results showed that impact of meteorological conditions on variability of plant height, time of maturity, 1000 kernel weight and grain yield of spring barley DH lines was of greater importance compared with the influence of genetic background.
