Abstract: Amyotte B., A.J. Bowen, T. Banks, I. Rajcan and D.J. Somers. Breeding apples is a long-term endeavour and it is imperative that new cultivars are selected to have outstanding consumer appeal. This study has taken the approach of merging sensory science with genome wide association analyses in order to map the human perception of apple flavour and texture onto the apple genome. The goal was to identify genomic associations that could be used in breeding apples for improved fruit quality. A collection of 85 apple cultivars was examined over two years through descriptive sensory evaluation by a trained sensory panel. The trained sensory panel scored randomized sliced samples of each apple cultivar for seventeen taste, flavour and texture attributes using controlled sensory evaluation practices. In addition, the apple collection was subjected to genotyping by sequencing for marker discovery. A genome wide association analysis suggested significant genomic associations for several sensory traits including juiciness, crispness, mealiness and fresh green apple flavour. The findings include previously unreported genomic regions that could be used in apple breeding and suggest that similar sensory association mapping methods could be applied in other plants.

Abstract: Cossentine, J., M. Robertson and R. Buitenhuis. Exposure of Drosophila suzukii adults to surfaces treated with Metarhizium brunneum, Beauveria bassiana, Isaria fumosorosea or Lecanicillium lecanii conidia under laboratory conditions resulted in fly infection and dose dependent mortality. Scanning electron microscopy confirmed that conidia accumulated on D. suzukii pretarsi after ≤48 h exposure to the dried conidia treated surfaces. Approximately 50% of the flies died post exposure to 1 × 108 conidia of each isolate distributed over approximately 148 cm2 by 7, 10, 12 and 13 days respectively at 25 °C. Temperature had an impact on fungus-induced D. suzukii mortality when tested at 20, 25 and 30 °C, although control mortality was also significant at 30 °C. Fifty percent of the control D. suzukii adults died after being held at 30 °C for 11–13 days. Significantly lower oviposition, recorded as F1 pupae, was recorded from adult D. suzukii exposed to M. brunneum compared to the number of offspring produced by control flies indicating that the fungus had a negative impact on fly fecundity. Evidence of transmission of acquired M. brunneum conidia between sexes was recorded.
