Effects of genotype by year interaction on some barleytraits

1997

Using the Eberhart and Russel method, we assessed the stability of yield, 1000-grain weight, and hectoliter mass in several major spring barley genotypes developed at the Institute of Field and Vegetable Crops in Novi Sad (Yugoslavia). The variability of yield and hectoliter mass depended for the most part on the year, while that of 1000-grain weight was almost equally dependent on the year and the genotype. The varieties differed significantly in their regression coefficient values and their deviation from regression. In order to fully exploit heterogeneous production conditions, we should develop spring barley varieties that will be characterized by good and stable agronomic and technological characteristics.
