Procurou-se verificar a preferencia varietal da mosca-branca, Bemisia tabaci (Genndius 1889) (Homoptera, Aleyrodidae), em cultivares e linhagens de soja, semeadas em solo hidromorfico, em Santa Maria, RS, nas safras 1978/79 e 1979/80. Para determinacao do nivel de infestacao, coletaram-se 30 folhas por parcela na safra 1978/79 e uma planta por parcela na safra 1979/80, nos quais foram realizadas as contagens, determinando o numero de ninfas e a area foliar. O nivel medio de infestacao, entre safras, foi quatro vezes maior na safra 1978/79 do que na 1979/80. A intensidade de infestacao entre os materiais mais e menos infestados variou de 100 e de 10 vezes nas safras 1978/79 e 1979/80, respectivamente. As cultivares Bossier e BR-1 e a linhagem DF-74/105 compor-taram-se como resistentes a mosca-branca. |

Soybean [Glycine max (L.) Merrill] is one of the most important legumes cultivated worldwide, and Brazil is one of the main producers of this crop. Since the sequencing of its reference genome, interest in structural and allelic variations of cultivated and wild soybean germplasm has grown. To investigate the genetics of the Brazilian soybean germplasm, we selected soybean cultivars based on the year of commercialization, geographical region and maturity group and resequenced their genomes. We resequenced the genomes of 28 Brazilian soybean cultivars with an average genome coverage of 14.8X. A total of 5,835,185 single nucleotide polymorphisms (SNPs) and 1,329,844 InDels were identified across the 20 soybean chromosomes, with 541,762 SNPs, 98,922 InDels and 1,093 CNVs that were exclusive to the 28 Brazilian cultivars. In addition, 668 allelic variations of 327 genes were shared among all of the Brazilian cultivars, including genes related to DNA-dependent transcription-elongation, photosynthesis, ATP synthesis-coupled electron transport, cellular respiration, and precursors of metabolite generation and energy. A very homogeneous structure was also observed for the Brazilian soybean germplasm, and we observed 41 regions putatively influenced by positive selection. Finally, we detected 3,880 regions with copy-number variations (CNVs) that could help to explain the divergence among the accessions evaluated. The large number of allelic and structural variations identified in this study can be used in marker-assisted selection programs to detect unique SNPs for cultivar fingerprinting. The results presented here suggest that despite the diversification of modern Brazilian cultivars, the soybean germplasm remains very narrow because of the large number of genome regions that exhibit low diversity. These results emphasize the need to introduce new alleles to increase the genetic diversity of the Brazilian germplasm. MenosSoybean [Glycine max (L.)
