Abstract

The objective of this work was to evaluate the stability and adaptability of cotton (Gossypium hirsutum L.) cultivars using the method of Eberhart & Russell (1966). Eleven varieties of cotton were tested at seven locations in Mato Grosso State, Brazil, in two growing seasons (2002/2003 and 2003/2004). The experimental design was the randomized complete blocks with four replications and the evaluated traits were lint percentage and seed cotton yield. For seed cotton yield, BRS Aroeira, BRS Ipê, BRS Cedro, BRS Jatobá and Delta Opal showed broad adaptability and stability in Mato Grosso State. However, for lint percentage there were not found cotton cultivars with both broad adaptability and stability for the studied environments.

KEY-WORDS: Gossypium hirsutum; lint; yield stability; genotype-environment interaction.
