Grain yield and quality reached by small grains are variable and affected by many factors, primarily by genotype, agroecological conditions and the applied production technology. Triticale is a plant species with high genetic potential for yield and favorable nutritional values, so it is consideredas promising. For achieving high and stable yields, it’s necessary to have favorable agroclimatic conditions of the locality, variety and advanced agricultural techniques, with a special turn to fertilizing. In this paper is given a review how agroclimatic conditions of the locality and variety influence on some morphological and productive characteristics of triticale. The experiment included two localities with different agroclimatic conditions, as well as two varieties of triticale (KG-20 and Tango). The experiment was set up as block system with three repetitions. Results were processed by analysis of variance. Applied cultural operations during the triticale growing were standard, with using of NPK 80:80:60 fertilizers. Investigations were carried out in Centre for Agricultural and Technological Results of the investigation showed significant influence of the locality on plant’s height, spike’s length, and number of grains in spike, grain’s mass per spike and yield of grains in triticale. All these characteristics had higher values in locality of Zajechar than in locality of Kraljevo. Variety Tango, in both localities, had significantly higher values of the investigated parameters than variety KG-20. The average yield for both varieties, the locality Zajecar was 6.40 t ha -1 , and the location of Kraljevo 5.16 t ha -1 , a difference of 1.24 t ha -1 . Higher yields on the locality Zaječar very significantly higher than at the locality of Kraljevo. Variety Tango, in locality of Zajechar , had about 0.9 t ha -1 higher yield than variety KG-20, while in locality of Kraljevo that difference was only 1.05 t ha -1 in favor of variety Tango. These differences are result of favorable climatic and soil conditions in locality of Zajechar in regard to locality of Kraljevo. These results are evidence for importance and role of agroclimatic factors and variety in expression of productive characteristics oftriticale.
