Nineteen wheat genotypes were evaluated in six experiments carried out in upland and under sprinkler irrigation conditions, in six different locations (two wheat production regions) of the State of São Paulo, Brazil, in 1992. The genotypes IAC 304, IAPAR 60, IAC 303, IAC 313, IAC 350, IAC 332, IAC 306, IAC 309, IAC 297, IAC 324 and IAC 325 presented good performance taking into account grain yield in upland conditions and IAC 312 and IAPAR 60 when sprinkler irrigation was used. The use of sprinkler irrigation increased the average grain yield of the experiments in 124%. The climatic conditions in Mococa region, and the use of irrigation improved the values obtained for test weight, the flour extraction, the sedimentation test, and deformation work (W), except for the farinograph parameters such as water absorption, the dough development time and stability. Only the mixing tolerance index was improved under this condition. The genotypes IAC 287, IAC 24, IAC 353, IAC 297, Anahuac and IAC 311 presented high dough stability and the genotypes IAC 24, IAC 353, IAC 297, Anahuac, IAC 306, IAC 313, IAC 311 and IAC 332 presented high W value, that is an indication of bread making quality. The correlation coefficient between sedimentation test and W was significant showing that this test may be used in the early generation of the quality genotype selection.
