The objective of the present study was to apply of the molecular marker system for detection of the allelic variants of the Wаx gene. Starch pasting properties are very important factors in malting, food processing and feed quality of barley cultivars. Therefore, it is important to control of the amylose/amylopectin ratio in the barley starch. The Wаx locus of barley (Hordeum vulgare L.) is responsible for the amylose endosperm biosynthesis. The Wаx gene may be found among the barley cultivars in several allelic variants: 2 functional active alleles encoding GBSS I protein and one null-allele with the inactivated enzyme.The most reliable way to assess the allelic state of Wаx gene is to use molecular marker based on polymerase chain reaction. Among the 126 barley samples studied (cultivars and breeding lines) by a codominant molecular marker system all of the three allelic variants of Wаx gene were identified. Two samples representing with the cultivars Candle and Alamo carried the null-allele of the Wаx gene. The results of the present study can be efficiently used to identify genotypes with the null-allele of the Wаx gene for developing and characterization of the new barley varieties.
