Triticale is the first synthetic cereal, the result of the cross between wheat (Triticum sp.) and rye (Secale cereale L.) being one of the greatest achivements obtained by man and a hardy crop with prolific growth and adaptation to various enviromental conditions that has been grown worldwide mainly for human food consumption and animal feed. The researches were performed in Agricultural Research-Development Station Lovrin during 2019 year, which is located in the northwest side of Banat, at almost equal distances from the cities of Timisoara and Arad (45-50 km). Biological material was composed of 10 varieties of autumn triticale (Plai, Titan, Stil, Haiduc, Negoiu, Pisc, Tulnic, Cascador, Utrifun and Vifor), that were created at National Agricultural Research and Development Institute Fundulea. In general, the studied varieties realise productions close to the average experience with insignificant differences. The amplitude of variability in the 10 triticale genotypes was 1133 kg/ha. The largest increases in production compared to the average experience was recorded in the varieties Plai (497 kg/ha) and Stil (330 kg/ha), without reaching the level of statistical assurance. According to the test of multiple comparisons, it results that any genotypes do it show significant differences in terms of triticale production, but are part of the same homogenity class A. The variation of production in the 10 triticale varieties under study was between 4177 kg/ha and 5300 kg/ha . The analysis of the yield was made by the perspective of yield elements (plant heigh, number of spike/m 2 , spike lenght, number of spikelets in spike, spike weight, grain weight and number of grains in spike) and how they influence the yield capacity of the autumn triticale varieties.
