RESUMO: O objetivo deste trabalho foi avaliar a eficiência e a praticidade de métodos de inoculação de Sclerotinia sclerotiorum, para uso na seleção de cultivares de soja resistentes ao mofo-branco. Avaliaram-se quatro métodos de inoculação, em plantas no estádio fenológico V3/V4. Aos três e sete dias após a inoculação, mediu-se o comprimento da lesão na haste das plantas. As cultivares de soja BRS 8460RR, BRSGO Ipameri e P98Y11 apresentaram as menores lesões. O método de inoculação por meio de ponteira no pecíolo é o mais eficiente e mais prático para avaliar a resistência ao mofo?branco em soja. ABSTRACT: The objective of this work was to evaluate the efficacy and usefulness of methods of Sclerotinia sclerotiorum inoculation for screening soybean cultivars resistant to white mold. Four inoculation methods were evaluated in plants at the V3/V4 phenological stages. Stem lesion length was measured three and seven days after inoculation. The soybean cultivars BRS 8460RR, BRSGO Ipameri, and P98Y11 had the smallest stem lesions. The inoculation method with pipette tip on the petiole is the most effective and practical to evaluate soybean resistance to white mold. |

The objective of this study was to assess the impact of pedigree, historical data, dominance, and data unbalance on the estimation and precision of genetic variances and breeding values and on the selection efficiency in annual crop breeding. Expansion volume and grain yield from 12 trials of inbred progeny and four tests of non-inbred families were used in the analyses. The S1 to S5 progeny trials were designed as incomplete blocks, the S6 progeny trials were designed as complete blocks, and the half- and full-sib family trials were designed as lattices. The half-sib, full-sib, and inbred family models were fitted in across-generation analyses. One complete and four reduced models were used to assess the relevance of pedigree, historical data, and dominance. Simulated plot losses of 30% in the half- and full-sib progeny trials were used to study the influence of data unbalance. All analyses were performed using ASReml. Ignoring pedigree information or ancestor data and simulating plot losses determined relevant biases in estimating the additive and dominance variances, marked reduction in the precision of the predicted breeding values, significant changes in the classification of the breeding values, and errors in identifying superior individuals, i.e., a significant reduction in the selection efficiency. In contrast, excluding dominance had no significant effect on either the ranking of breeding values or selection efficiency. Our results revealed that best linear unbiased prediction including pedigree and historical data, based on a model with dominance, is the ideal method for genetic evaluation by plant breeders even when lost records are considered.
