“…On the other hand, it was higher than that suggested by FAO66 [7]; this may be because the K c used was calibrated and tested for olives. In fact, olive trees are an evergreen and resilient species that are well adapted to the Mediterranean environment [26,27,33]; meanwhile, hazelnut is sensitive to water stress and prefers cooler and more humid environmental conditions [34,35]. However, for the medium density (1250 trees ha −1 ), the K c,Tr determined for hazelnut in this research was very similar to that of FAO66 [7].…”

Knowledge of crop water requirements is important in supporting irrigation management. Evapotranspiration (ET) is commonly measured with a variety of instruments and field procedures, but it is also typically computed or modeled using the FAO56 or FAO66 methods. The adoption of this approach requires the assessment of the crop coefficients. Some data are available for own-rooted hazelnut trees, but no data have been reported for young and grafted hazelnut trees. There is a need to update nut–tree crop coefficients, especially considering modern cultivars and production systems, such as those with a high tree density per ha−1. In this paper, the FAO66 crop transpiration coefficient Kc,Tr and the FAO56 dual crop coefficients Kcb were assessed for the mid-growing season of a young grafted hazelnut orchard. The field data were acquired manually and using UAV. The coefficients were determined for three tree densities and for two growing seasons. The crop coefficients, obtained using the FAO66 method, agreed with the literature data referring to low densities, while the FAO56 method could allow us to better define the crop coefficients for high-density hazelnut orchards.

“…Multiple density peaks were also observed in Spain at different timings and were correlated with both optimal mean temperatures and reduced insecticide treatments [29]. In the "Altopiano del Fucino" area, the mean daily temperatures, which are known to be optimal for psyllid development (around 25 • C), were actually registered in June and then in late August 2022, whereas the temperatures were much higher in July and early August and were thus less favorable for a high population density [53]. No insecticide treatments specifically targeting psyllids were performed in the considered area, but the routine chemical control of other insect pests, mainly aphids and the carrot fly Chamaepsila rosa [54], could have affected the trend of the population density of B. trigonica.…”

“…It was observed that the number of B. trigonica specimens decreased in the absence of the host crop but was never zero, and few specimens continued to be caught until the end of the survey despite the upcoming cold season. In the "Altopiano del Fucino" area, the mean daily temperature registered in October 2022 was 9.1 • C only, and the minimum monthly temperatures even went down to 0 • C [53]. This suggests that B. trigonica, which is known to prefer mild climates, can survive the low temperatures occurring in autumn in the "Altopiano del Fucino" area.…”

Psyllids, members of the family Triozidae, represent a potential threat to the cultivation of solanaceous and apiaceous crops worldwide, mainly as vectors of the phloem-restricted bacterium ‘Candidatus Liberibacter solanacearum’ (Lso). The Lso haplotypes C, D and E are known to affect apiaceous crops, such as carrot and celery, in several European countries. In Italy, data on the incidence and natural spread of both Lso and psyllids have not been reported so far. In this study, the presence of the vectors was investigated in a main Italian district for carrot production, the “Altopiano del Fucino” area (Central Italy). Both occasional and regular surveys were carried out on a total of five carrot fields and one potato field in 2021 and 2022. Bactericera trigonica (Hodkinson), which is known to efficiently transmit Lso to carrots, was found to be well-established in the area. High levels of population density were recorded in the summer period (more than 100 adult specimens per trap caught every two weeks) and then sharply decreased after the carrot harvest, confirming the strict association of this psyllid species with crop availability. In 2022, 27.5% of the total tested psyllid samples resulted in being positive for Lso haplotypes D and E, the latter being prevalent. This survey revealed, for the first time in Italy, the presence of B. trigonica adults associated with Lso in carrot crops. Although this study was limited to a few fields located in one area, it provided important evidence of the risks for Lso outbreaks and prompted further research to assess the spread and incidence of the disease in apiaceous cultivations in Italy.

“…This production is driven by a wide range of market uses across diverse industries, including food products, pharmaceuticals, and dietary supplements (Ceylan et al, 2022). Currently, commercial cultivation relies overwhelmingly on cultivars of European hazelnut (C. avellana) adapted to Mediterranean climates (Di Lena et al, 2022) with moderate winters to satisfy their chilling requirements (Mehlenbacher, 1991). The distribution of hazelnut production reflects these climatic requirements, with major centers of production in Turkey, Italy, and Spain, with Turkey alone producing over 65% of the global supply (Semih Uzundumlu et al, 2022).…”

The native shrub American hazelnut (Corylus americana) is currently used in breeding programs that are aiming to develop commercially viable hazelnut varieties for the U.S. Upper Midwestern U.S. This species provides significant ecological benefits as it is a perennial crop and well-adapted to this region. Breeding cycles for perennial species are long, and may benefit from the use of predictive methods such as genomic selection to reduce cycle time and increase the efficiency of field trials. High-quality reference genome assemblies are very useful for the implementation marker-assisted selection and genomic prediction, and we therefore developed the first chromosome-scale reference assemblies for C. americana, using the accessions 'Rush' and 'Winkler'. Initial draft assemblies were created using HiFi PacBio reads and Arima Hi-C sequencing to assemble genomes into 11 pseudomolecules. We then utilized Oxford Nanopore reads and a high-density genetic map in order to perform error correction. N50 scores were calculated to be 31.9 Mb and 35.3 Mb for 'Rush' and 'Winkler', respectively, while 97.1% (for 'Winkler') and 90.2% (for 'Rush') of the total genome was assembled into the 11 pseudomolecules. Gene prediction was performed using both RNAseq libraries as well as protein homology data. 'Rush' had a BUSCO score of 99.0 for its assembly and 99.0 for its annotation, while 'Winkler' had corresponding scores of 96.9 and 96.5, indicating extremely high-quality assemblies. These two independent, de novo assemblies enable unbiased assessment of structural variation across the genome, as well as patterns of syntenic relationships within C. americana and the Corylus genus. These assemblies are also an important first step in providing a resource for using next-generation sequencing data in the improvement of C. americana. We demonstrate this utility through the generation of high-density SNP marker sets from genotyping-by-sequencing data for 1,343 C. americana, C. avellana, and C. americana x C. avellana hybrids, in order to assess population structure in natural and breeding populations. Finally, the transcriptomes of these assemblies, as well as several other recently published Corylus genomes, were utilized to perform phylogenetic analysis of sporophytic self-incompatibility (SSI) in hazelnut, providing further evidence of unique molecular pathways governing self-incompatibility in Corylus not exhibited in other well-studied SSI systems. We hope these assemblies will aide in the application of modern breeding methods to the development of commercially viable hazelnut varieties for the U.S. Upper Midwest.
