Recent advances in agriculture phenotyping gave rise to a plethora of speedy and non-destructive screening tools, one of which is the Normalized Difference Vegetation Index (NDVI) technology, widely used for estimation of yield components, biomass and other important physiological traits for crop production. The objective of this study was to evaluate NDVI values and relationship with agronomic characteristics in a diverse set of barley advanced lines. The selected plant material consisted of 24 six-rowed and 23 two-rowed elite barley lines developed at the Institute of Field and Vegetable Crops from Novi Sad. The trial was conducted in a complete randomized block design with four replications at the experimental field Rimski šančevi in 2017/18. The NDVI parameters were collected using the handheld Green Seeker sensor at the anthesis vegetation stage (Zadoks 65), while the following agronomic traits were measured during the growing season: stem height, spike length, hectoliter mass, th...ousand grain weight and grain yield. Significant correlations between NDVI and grain yield were detected in two-rowed (R2=0.363) and six-rowed (R2=0.268) barley genotypes. The observed positive correlations with stem height were stronger in two-rowed (R2=0.459) than in six-rowed (R2=0.257) genotypes, whereas the relationship between NDVI and thousand grain weight was significant only in six-rowed barley lines. Genotype variation in NDVI values and, especially, its positive correlations with yield indicate that NDVI technology could be used as an additional tool for selection of early maturing genotypes with better adaptation traits, which could accelerate development of better performing cultivars resilient to future unpredictable changing climate.
