Influence of environments on the amount and stability of grain yield in modern winter wheat cultivars I. Interaction and degree of variability

N. Tsenov, D. Atanasova Abstract. Numerous common wheat varieties have been developed in Bulgaria, which when grown under variable environments, the magnitude of the grain yield is influenced by them. In order to determine the reasons for such variations the effect of the growing cond
