GRAIN YIELD AND NUTRITIONAL QUALITY OF DIFFERENT RYE GENOTYPES

Abstract

Rye (Secale cereale L.) has a high tolerance to cold, drought, diseases and pests. Besides, rye improves soil structure, builds organic matter and helps protect again water and wind erosion. The aim of this study was to determine the grain yield and quality of rye as feed in Central Anatolian conditions. For this purpose, nine landrace and one variety (Aslim-95) of rye and one variety of triticale (Karma-2000) were investigated for grain yield, crude protein content, acid detergent fiber (ADF), neutral detergent fiber (NDF), potassium, phosphorus, calcium, magnesium, total phenolic, total flavonoid, DPPH free radical scavenging activity and condensed tannin content. Experiments were carried out in Yozgat ecological conditions in 2018-2019 and 2019-2020 growing seasons in a randomized block design with three replications. There were significant (p<0.01) differences between genotypes and years in terms of grain yield and all the nutritional quality traits. According to the quality traits, it was determined that some landraces have better performance than the variety of rye and triticale. As result, it was determined that the landraces have the potential to be used as a genetic resource in breeding studies in terms of yield and quality traits for feed type rye.
