The genetic control of rust resistance was studied using the Caiapônia x IAC-100 and Luziânia x Potenza crosses. The F2 and F3 generations were evaluated. Rust severity was quantified through visual assessment of the middle third of three leaflets per plant and performed by three different evaluators; the average score was calculated foreach individual plant. From these data, we estimated the mean and variance of the genetic components by employing the weighted least squares method. The estimated number of genes and broad- and narrow-sense heritabilities were also obtained. It was concluded that rust resistance is a characteristic controlled by 2 to 23 genes that are predominantly dominant. The estimate of narrow-sense heritability was greater than 70% for...

The purpose of this study was to evaluate the phenotypic adaptability and stability for grain yield of soybean genotypes by the method of Annicchiarico and the Integrated Method of adaptability and stability analysis and to identify the genotypes with best performance under environmental variations. The agronomic performance of semilate and late genotypes maturing, was evaluated in the final evaluation trials of the Program of Soybean Genetic Improvement of the UFV, in Viçosa, Florestal and São Gotardo, State of Minas Gerais, in the 2006/2007 and 2007/2008 growing seasons. All field experiments were arranged in a complete randomized block design with 14 treatments and three replications. Line CS 02736 and cultivar UFV TN 105 were classified as adapted to...
