Abstract

With the introduction of commercial soybean genotypes with Als1 and Als2 alleles that confer tolerance to different active ingredients of sulfonylurea group, this work aims to test soybean populations for the presence/absence of Als1 and Als2 alleles and evaluate the agronomic impact of these alleles addition. These trials were conducted in experimental stations of DuPont Pioneer at Sorriso, Mato Grosso state and Planaltina, Federal District. Four populations were evaluated with 40 genotypes each; 10 genotypes without Als1 and Als2 (null), 10 genotypes containing Als1, 10 containing Als2 and 10 genotypes containing both alleles. These populations were tested for different traits. The grain yield average at Planaltina and Sorriso were 2888 and 2456 kg ha-1, respectively. Yield for the genotypic classes null, Als1, Als2 and Als1+Als2 were 2672, 2671, 2631 and 2657 kg ha-1, respectively, and they were not statistically different from each other. Also, the other traits indicated similar behavior among classes. As the studied populations were developed for this study, they were inferior than the checks. This work demonstrated that in the four studied populations, the addition of Als1 and/or Als2 alleles did not cause significant differences in the evaluated traits.
