Development of the new waxy winter wheat cultivars Eldija and Sarta

Abstract

Two new waxy winter wheat (Triticum aestivum L.) cultivars, Eldija and Sarta, were developed at the Institute of Agriculture, Lithuanian Research Centre for Agriculture and Forestry and released in Lithuania in 2021. The cultivars were developed using waxy wheat material from Nebraska, the United States of America. The mean yield of Eldija and Sarta at five locations over three testing years was 7.56 and 7.21 t/ha or 79.63 and 75.95%, respectively, compared to the yield of the standard cultivars. Eldija and Sarta should be grown under high input conditions due to the relatively low resistance to leaf spot diseases and Fusarium head blight and medium tolerance to lodging. An amylose content of 0.68% and 0.36% of Eldija and Sarta, respectively, a very low falling number (about 60 s), a lower flour yield and higher water absorption compared to common wheat and the reaction to iodine staining (brown colour) characterised the new cultivars as fully waxy wheats. These cultivars are intended for the potential demand from commercial companies for special use in the food industry.
