Evaluation of triticale genotypes under low land conditions in the State of São Paulo, Brazil

Abstract

Experiments involving triticale genotypes carried out under low land conditions, at the Mococa Experiment Station, in Mococa, SP, Brazil, during 1985-92, were evaluated in relation to grain yield and to the occurrence of sterile spikelets. The triticale cultivar IAC 1 showed high grain yield in comparison to the other cultivars studied, and good adaptation to these soil conditions. The wheat cultivars IAC 5 and IAC 60 used as controls presented low productivity. The triticale cultivars IT 8029, TCEP 8136, ICT 8433, ICT 8437 and BR 2 showed high percentages of occurrence of sterile spikelets: above 50%. The triticale cultivar PFT 7882 exhibited the lowest percentage of sterile spikelets.
