EVALUATION OF TRITICALE GENOTYPES UNDER L OW LAND CONDITIONS IN THE STATE OF SAO-PAULO, BRAZIL

Experiments involving triticale genotypes carried out under low land c onditions, at the Mococa Experiment Station, in Mococa, SP, Brazil, du ring 1985-92, were evaluated in relation to grain yield and to the occ urrence of sterile spikelets. The triticale cultivar IAC 1 showed high grain yield in comparison to the other cultivars studied, and good ad aptation to these soil conditions. The wheat cultivars IAC 5 and IAC 6 0 used as controls presented low productivity. The triticale cultivars IT 8029, TCEP 8136, ICT 8433, ICT 8437 and BR 2 showed high percentag es of occurrence of sterile spikelets: above 50%. The triticale cultiv ar PFT 7882 exhibited the lowest percentage of sterile spikelets.
