Evaluation of and Variability in Yields and Yield Components of Wheat Cultivars in Northern Serbia

Summary The purpose of this research is to examine the variability in yields and yield components wheat cultivars Northern Serbia, visualize their groupings relationships, determine correlations between traits using principal analysis (PCA). A total fifteen genotypes (Triticum aestivum L.), developed 10 different countries over a period exceeding 70 years, were analyzed during growing seasons 2018/2019 2019/2020 at Rimski šančevi, experimental station Institute Field Vegetable Crops Novi Sad. phenotypic was performed for following traits: spike weight, number spikelets per spike, grains thousand grain yield. Data descriptive statistics, an variance, correlation interactions considered, PCA. results obtained indicate significant differences according all examined. revealed positive produced nearly components. PCA confirmed relationship examined, grouped performance, highlighted eligible future breeding research.
