Performance of resistant soybean to Asian rust in different environments in rs

This study aimed to test performance resistant soybean to Asian rust in different environments of Rio Grande do Sul. The experiment was conducted in the agricultural year 2013/2014 in five producer of soybeans regions of Rio Grande do Sul. The experiment was conducted in randomized block design, arranged in four replicates. Data were subjected to variance analysis by F test, and the means were performed comparing by Duncan test at 5% probability of error, in the Genes statistic program. Soybean rust resistant does not have the same performance at all cultivation environments, indicating that a narrower agricultural zoning should be effected. The best performance of soybean rust resistant is expressed in Derrubadas, under the variable grain yield, grain yield per plant, number of branches and number of pods with 2 and 3 grains.
