A new antagonist/pathogen combination is reported, with Bacillus pumilus showing strong antagonistic activity against Penicillium digitatum. B. pumilus (1.6 x 10^10 to 1.6 x 10^12 cfu ml-1) gave significant control of P. digitatum infection in Valencia orange, which was as effective as imazalil (500 mg ml-1) and was significantly better than benomyl treatment (500 mg ml-1). When lower concentrations of B. pumilus (1.9 x 10^7 to 1.9 x 10^9 cfu ml-1) were tested on Washington Navel orange and Lisbon lemon fruit, the antagonist caused significant control of P. digitatum infection at two inoculum levels (6.5 x 10^4 and 6.5 x 10^5 spores ml-1). Concentrations of both pathogen and the antagonist affected the biocontrol effect. |

Conteúdo: |
The autotetraploid forage Congo signal grass (Brachiaria ruziziensis) is an important component in the Brachiaria breeding programme. As with other tropical forage grass species, the association between flowering and seed yield components, the mode of inheritance and the effects of population structure on phenotypic breeding are lacking. Seventeen characteristics evaluated in 59 half-sib progeny of seven subpopulations were analysed using a mixed model methodology. According to the commonality analysis, the total seed yield (0.67) and number of days to flowering (0.22) had a greater influence on the filled-seed yield. The flowering synchrony, total number of panicles, filled-seed yield, green matter yield and dry matter yield presented statistically significant additive genetic variance between and within the subpopulations. The QST estimates ranged from 0.09 for the flowering synchrony index to 0.31 for the filled-seed yield. The effects of population structure and its use in breeding programmes are further discussed. |
