FELICIO, João Carlos et al. Adaptability, stability and yield potential of Triticum durum L. genotypes under sprinkler irrigation in the State of São Paulo. Bragantia [online]. 2005, vol.64, n.3, pp.377-387. ISSN 0006-8705.

In order to evaluate Triticum durum L. genotypes having as control the T. aestivum L. cultivar IAC, 24 experiments were carried out, under sprinkler irrigation, at Votuporanga, Ribeirão Preto and Mococa locations, in the period 1998 to 2002, in the State of São Paulo. Grain yield and performance of each genotype in relation to the environment variation were evaluated. Adaptability and stability analysis were made identify genotypes with predictable performance in these environment conditions. Significant effects were observed for years, locations and genotypes. Considering the three locations, Triticum durum inbred line 11 (MEMOS"S"/YAV79/3/ SAPI"S"/TEAL"S"// HUI"S") presented the highest yield. The highest grain yields were observed in Ribeirão Preto and the lowest in Votuporanga. Inbred lines 9 and 11 (MEMOS"S"/79/3/SAPI"S"/TEAL"S"//HUI"S"), 12 and 19 (GYS"S"/3/STN"S"//HUI"S"/SOMOS"S") and 3 STN"S"/3/TEZ"S"/ (YAV79//HUI"S") showed specific adaptability, thus being responsive to high technology use. Leaf rust incidence was only verified in the T. aestivum cultivar IAC 24.

Keywords : grain yield; diseases; regional adaptation.
