Em experimentos conduzidos de 1982 a 1984 nos municípios de Maracaí, Mococa e Paranapanema, comparou-se o comportamento de dezoito cultivares de triticale com dois de trigo. Considerando os ensaios em conjunto, as análises revelaram efeito significativo ao nível de 1% para cultivar, local e ano e para as interações cultivar x local e local x ano. A interação cultivar x ano demonstrou significância ao nível de 5%, indicando que o comportamento dos cultivares foi mais pronunciado em relação a local do que a ano. Os cultivares de triticale PFT 7882, PFT 7719, TCEP 7846, TCEP 7718, TCEP 7889, TCEP 77138, PFT 766, TCEP 7789, PFT 7893, PFT 7228 e TCEP 77140 foram os mais produtivos. Os cultivares de trigo apresentaram baixa produtividade em solos de várzea úmida, maior peso hectolítrico (PH) e menor peso de mil sementes em relação aos de triticale. A incidência de moléstias, como a ferrugem-do-colmo e da-folha, foi bem maior nos cultivares de trigo; para manchas foliares ocasionadas por Helminthosporium sp. e Septoria sp., a suscetibilidade do triticale foi semelhante à do trigo.

Eighteen triticale and two wheat cultivars were evaluated in field experiments in order to test their yield capacity, resistance to prevailing diseases and agronomic and seed characteristics. The experiments were carried out at three locations in the State of São Paulo during the years of 1982, 1983 and 1984. Grain yield, number of days from emergence to maturation, head length; head sterility; weight of 1000 grains, number of grains per gram, weight of one hectoliter, resistance to stem and leaf rust and other leaf diseases were evaluated under field conditions. In relation to grain yield it was found high significant effect of cultivars, locations, years, cultivars x location and locations x years. The interaction between cultivars and years was significant at the 5% level. The effect of locations was more evident than years in the cultivars performance. The triticale cultivars PFT 7882, PFT 7719, TCEP 7846, TCEP 7718, TCEP-7889, TCEP-77138, PFT-766, TCEP-7789, PFT-7983, PFT 7228 and TCEP-77140 showed the best grain yield considering all experiments. The wheat cultivars presented low yield compared to triticale cultivars in Mococa (lowland condition) due to occurrence of a severe head sterility. The wheat cultivars in general showed higher weight of one hectoliter and lower 1000-grain-weight in relation to triticale cultivars. Wheat cultivars were more susceptible to leaf and stem rust compared to triticale and no significant differences were found among wheat and triticale cultivars in relation to resistance to Helminthosporium sp. and Septoria sp., both species are susceptible to these diseases.
