Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Aim. The aim of this research was to create waxy barley forms by hybridization and to test them for high amylopectin
content in starch. Methods. To create high-yielding waxy lines, we used hybridization methods. Results. Due to using
spring barley forms with various amylopectin content in starch in breeding, high-yielding lines with starch, which almost
completely consists of amylopectin, were effectively created. The range of lines with amylopectin starch was broadened:
nutans, medicum and rikotense were obtained. In 2014–2015, the variety trials distinguished the best eight lines, seven
of which (12-945, 12-954, 12-965, 12-1014, 12-333, 12-473, 12-476) gave high yields (107%, 105%, 105%, 116%,
110%, 107%, 115% related to the standard) and were lodging resistant (8.5–9.0 points) with identical or slightly different
duration of the vegetation period. The waxy lines distinguished are sources of high amylopectin content in starch and
valuable agricultural characteristics. Conclusions. The effectiveness of high-yielding waxy line breeding was shown.
Waxy lines with 5–16% higher yield capacity and high lodging resistance (8.5–9.0 points) were selected.
Keywords: spring barley, waxy starting form, waxy line, amylopectin, yield.
