The global acceleration warm conditions determine an additional stress for plant growth and development stages with a high impact on plant grain yield performances. During five experimental years the climatic conditions varied quite a lot so that the main productivity elements: the number of grains/spike, weight of grains per spike and number of spikes per square meter had different values which influencing final grain yield. Analyzing the relationship between rainfall/temperature and grain yield, including its components, can be observed a strong relation between those especially in the first growth stages (from plant emergence and vegetative restarting in early spring). Climatic conditions have manifested an important influence also in the last phenophases of winter triticale plant with a negative influence on grain yield. Being a process of long duration, grain yield formation is strongly affected by temperature (r=0.89) and rainfall conditions (r=0.45).
