Wheat cultivation in rainfed conditions is a good option for regions in Minas Gerais with altitudes above 800 m. The objective of this study was to estimate the genetic diversity of eleven wheat genotypes grown in rainfed conditions, using multivariate analysis based on six morpho-agronomic traits to identify which genotypes have potential for hybrid combinations. The treatments were arranged in a randomized complete block design with four replicates. The experiments were carried out during the wheat cropping season 2007/2008. Great variability was found among the wheat genotypes evaluated in rainfed conditions. The genotypes IAC 289-L22 and IAC 289-L4 were the most similar. The genotypes CD 113 and EP 011106 were the most diverging and the most promising for breeding towards generating material adapted and with good characteristics for rainfed cultivation.
