During the past century, grain yield potential in winter wheat has been continuously improved as the result of changes in production technology and development of modern high-yielding cultivars. Previous studies of the grain yield progress in winter wheat has been mainly restricted to the analysis of changes in main grain yield determinates, such as grain weight and grain number. However, there is a lack of information about changes in stay green pattern related to breeding progress in winter wheat. Therefore, the main objective of this paper was to analyse the changes in the stay-green traits related to the grain yield improvement in a historical set of 25 winter wheat cultivars released during the last century.This Symposium honours the centenary year of the birth of academician Slavko Borojević, famous geneticist, plant breeder, agronomist and professor. It was organized by the Serbian Academy of Sciences and Arts - Branch in Novi Sad, Faculty of Agriculture of the University of Novi Sad, and Institute of Field and Vegetable Crops Novi Sad, and financially supported by the Provincial Secretariat for Higher Education and Scientific Research
