Abstract:
... Analysis of composite pecan leaf samples typically used to determine need for nutrient applications does not account for variability among trees in the sampled area. To account for this unmeasured variability, pecan orchard block nutrient standards are greater than actual single tree nutrient requirements. In 2018 and 2019, we measured variability in a pecan orchard block by evaluating nutrient st ...

Abstract:
... The primary approach for variety distinction in Italian ryegrass is currently the DUS (distinctness, uniformity and stability) test based on phenotypic traits. Considering the diverse genetic background within the population and the complexity of the environment, however, it is challenging to accurately distinguish varieties based on DUS criteria alone. In this study, we proposed the application o ...
... Participatory plant breeding and rapid sensory evaluation are effective techniques for organic cultivar development. Table beet is an important crop for organic growers, and geosmin, a volatile compound which confers earthy aroma, has been suggested as the attribute around which hedonic liking of beet is organized. Open pollinated table beet populations with diverse pigmentation and low (LGC) or h ...
... In forest tree breeding programs, open-pollinated families are frequently used to estimate genetic parameters and evaluate genetic merit of individuals. However, the presence of selfing events not documented in the pedigree affects the estimation of these parameters. In this study, 194 open-pollinated families of Eucalyptus globulus Labill. trees were used to compare the precision of estimated gen ...
... The study of vegetative phenology is important to understand adaptation to different environments and potential trade-offs with growth traits. Crown leaf-out and leaf-fall phenology was evaluated on 168 open-pollinated families from 19 Cedrela odorata provenances in an eleven-year-old provenance/progeny trial established in the state of Veracruz, Eastern coast of Mexico. The objectives were: (a) t ...

... Physiological responses of different interspecific Pyrus hybrids and an open pollinated Pyrus communis ‘Williams’ (Pcw) grown under in vitro culture conditions simulating lime induced chlorosis were studied. The hybrids were derived from crosses between the ‘Pyriam’ pear rootstock and four Pyrus species of the Mediterranean region, namely P. amygdaliformis Vill. (Pa), P. amygdaliformis persica Bor ...

Abstract:
... Pollinator richness, abundance and visitation frequency may be affected by the abundance of floral resources and abiotic factors, influencing plant reproductive success. We analysed whether the diversity, abundance and frequency of butterfly visitation on Lantana camara vary across the year in a tropical urban landscape and whether this variation in butterfly community influences plant’s reproduct ...

Abstract:
... KEY MESSAGE: Cytoplasmic male sterility in sugar beet becomes thermo-sensitive when combined with specific genotypes, potentially offering a means to environmentally control pollination by this trait. The stability of cytoplasmic male sterility expression in several genetic backgrounds was investigated in sugar beet (Beta vulgaris L.). Nine genetically heterogenous plants from open-pollinated vari ...
... Prosopis chilensis (Molina) Stuntz (Leguminosae) is a valuable native species in Argentina that has been proposed to be used in reforestation, afforestation and restoration programmes. Natural provenances show important differentiation in height, shape, spine size, fruits and foliar traits throughout their distribution in the semiarid Monte ecoregion. The goal of this work was to characterize the ...

Abstract:
... Breeding for new ornamental varieties is quite often a profitable occupation in the world. Worldwide breeding activities have generated a massive amount of literature. All present day ornamental varieties have evolved through bud sports, open pollinated interspecific crosses, open pollinated intraspecific crosses, planned crosses, natural chromosomal changes, chromosomal manipulations, induced mut ...

Abstract:
... Althea (Hibiscus syriacus) is a popular shrub known for its vibrant summer blooms and winterhardiness; however, althea produces capsules with numerous seeds that germinate and cause a nuisance in production and the home landscape. Breeding for sterile forms has long been a goal of Hibiscus breeders, yet many popular “sterile” cultivars have been reported as weedy. The purpose of this study was to ...

Abstract:
... Cultivated Japanese pear varieties, mostly showing self‐incompatibility, require pollen transfer from other varieties. To elucidate the underlying mechanisms of open Japanese pear insect pollination, we first collected flower‐visiting insects using plastic vials and sticky traps in orchards located at different regions in Japan. Results showed that insects assigned to the families Andrenidae (Hyme ...
... The 'NDOLA-2' (Reg. No_, PI_) is an open-pollinated non-GMO spring-type canola developed at North Dakota State University (NDSU) and approved for specialty release by the North Dakota Agricultural Experiment Station. NDOLA-2 was tested as an experimental line 'NDC-E16198' from 2017 to 2020 (16 location-year) in NDSU canola breeding nurseries, and in 2019 and 2020 (8 location-year) in North Dakota ...

... Depressed fruit and seed production and scant seedling recruitment appear to be imperiling natural populations of Colombian Magnolia species. From February 2015 to April 2017, we recorded data on flowering, pollen limitation, floral visitors, and the reproductive phenology of Magnolia jardinensis and Magnolia yarumalensis, two threatened and endemic species from Colombian Andean cloud forests. Bot ...

Abstract:
... This study assessed the levels of mycotoxins in maize from Kenyan households. Further, local open pollinated maize varieties were compared with commercial hybrids to evaluate which variety is less susceptible to mycotoxin contamination. Four hundred and eighty (n = 480) maize samples were collected in the years 2018–2020 from households in Eastern, Western, Coastal and Lake Victoria regions of Ken ...

Abstract:
... In industrialized countries, maize cultivation is mainly associated with the use of hybrid varieties and input-intensive monocultures. Despite the homogeneity of European maize landscapes, alternative models of maize production based on landraces exist. Understanding the structures and values underlying these models is essential to enable the design of new strategies linking crop diversity, plant ...
