Knowledge of the genetic effects that control a trait is essential to direct the breeding program for gains in the selection process. The main objective of this study was to investigate the genetic control of soybean resistance to brown spot. Two tolerant cultivars (FT-2 and Dourados) and two susceptible cultivars (Davis and Paraná) and the segregant F2 and F3 generations derived from the crosses between these cultivars were assessed for reaction to the disease after inoculation. Genetic models were adjusted to the means and variances of the generations. It could be concluded that the trait is governed by various genes with lesser effect, has low to medium heritability and selection should be made always using progeny from the F3 generation and can be made during the initial stages of soybean growth, based on the mean of at least two trifoliate leaves. |

Conteúdo: |
Aiming at determining the level of nitrogen applied through fertirrigation, appropriate for good grape plant development, better fruit quality and higher yield, an experiment was carried out in Petrolina- PE, located in the semi-arid region of the Brazilian Northeast. In a randomized blocks experimental design with split-plots were studied five seedless table grape cultivars (‘Perlette’, ‘Thompson Seedless, ‘Marroo Seedless’, ‘Catalunha’ and ‘Superior Seedless’) and four nitrogen levels (0,75, 150 and 300 kg ha-1N). Application of fertilizers was done by microsprinkler. |
