According to maximal grain yields of the varieties with different growth ratios, realized when fungicide was applied later than proposed, knowledge about development speed, damage when were covering last two leafs (each 10% estimated before harvesting, caused 3,5 % grain yield loss) as effects of the interactions between facultative and obligate parasites, grain yield equilibrium was defined. Results of the varieties Rapsodija and Sonata with same GR differences from Pobeda in two directions, without specific resistance to Puccinia triticina (short latency period) when Pyrenophora tritici repentis was equally developed because of the late primary infection, confirmed the difference in grain yield of – and + 7%. By the results of reactions to Puccinia triticina and GR values of seedlings was predicted the constellation of related factors for realizing the higher grain yields of standard variety Pobeda in Serbian commission trial 2010th and predicted effects of growing in production.
