Evaluation of triticale genotypes in lowland condition in the state of São Paulo during the period 1979-1984

Abstract

It was carried out at Paraíba Valley in lowland conditions comparative trials to study triticale and wheat cultivars. The experiments were planted in Lorena and Pindamonhangaba during the period of 1979 to 1984. The triticale cultivars presented superior grain yield compared with the wheat cultivars under study. Triticale cultivars exhibit less head sterility in relation to wheat cultivars. TCEP-77138 presented good performance among the studied triticale cultivars. Generally the triticales showed better stem and leaf rust resistence than the wheat cultivars; although triticales presented more susceptibility to Helminthosporium sp. than the wheat cultivars. The triticale cultivars showed good resistence to lodging and presented low plant height in comparison with the wheat cultivars.
