Adaptability and productive stability of tomato genotypes in high temperature

The objective of this work was to evaluate the adaptability and stability of 15 tomato genotypes in the area of Gurupi, Tocantins. The experiments were carried out in two environments [greenhouse: in the summer (December to March) and in open field: winter (June to September)], with 15 experimental tomato genotypes, being: four of the type long shelf life commercial ripening mutants and pre-commercial (rin): Tyler, Rebeca, Carmem and AF 13527; nine of the type long shelf life structural commercials and pre-commercial: Lumi, Debora Max, Michelli, Tammy, AF 12525, AF 11097, AF 13363, AF 13364 and AF 13525; and two of normal fruits: Santa Clara and Drica, in randomized block design with three repetitions. The long life genotypes e Tyler, Rebeca, AF 13364, AF 13525, AF 13527 it were classified as of stability and wide adaptability and wide adaptability for yield. For the average weight of commercial fruits, the genotypes Tyler, Michelli and AF 11097 presented wide adaptability to the evaluated environments.
