Field assays in three different experimental paddy fields, and one upland nursery field in Daisen, Gozenyama, and Inabu were used to evaluate blast resistance (Figure 2).
This study was carried out at the Agriculture and Biological Division, National Research Centre NRCC), as well as within a disease nursery field located at Gharbia Governorate, Egypt, during the 2016 growing season.
The system can also reverse the former procedures to retrieve sprouted trays from pallets and arrange the trays to be sent to the nursery field, where the seeds in the tray keep growing to the seedling stage.
The Daisen fields in Akita prefecture possess suitable field conditions for blast disease development (Shindo and Asaga [1989]), and were used in 2000 for evaluation of panicle blast resistance in an experimental paddy field, and leaf blast resistance in an upland nursery field using F3 lines.
In this study, we evaluated the resistance of the RDP1 cultivars in rice blast nurseries (field sites containing highly diverse M. oryzae populations) in three representative rice production regions of China.
Its accurate detection in nursery and field samples is of high importance for certification schemes and disease management programmes.
A systematic nursery and field research strategy was used to develop a reforestation program based on mixed plantings of more than 70 native old-growth forest tree species.
Isolates of the fungus Fusarium oxysporum cause some of the most devastating plant diseases, leading to significant crop losses in both the greenhouse nursery and field environments.
On the other hand, the Pearson's correlation coefficient between nursery and field conditions, based on family mean for height, was moderate and negative (R = −0.40, P = 0.02), indicating a low correspondence between both environments.
