Onion response to irrigation criteria for two varieties at two plant populations. Past research at the Malheur Experiment Station demonstrated the sensitivity of onion yield and grade to soil water tension (SWT) (Shock et al. 2000). The ideal SWT for initiating irrigations for drip... ... Repository: BDPA Publication year: 2014
Survival of Escherichia coli on onion during field curing and packout. The Food and Drug administration has expressed concern that Onions (Allium cepa) irrigated with water contaminated with high rates of Escherichia coli could harbor E. coli on their surface or interior... ...

Partial success of marker-assisted selection of A and B onion lines in Brazilian germplasm. This work aims to identify A and B onion lines in Brazilian germplasm, associating marker-assisted selection (MAS) of cytoplasm type and the Ms ocus with pollen viability analysis. MAS and pollen viab... ... Repository: BDPA Publication year: 2018
Water-use efficiency and onion quality in future climate scenarios. Considering that changes in climatic parameters directly interfere in crop yields, this study aimed to evaluate the impact of changes in carbon dioxide concentrations, temperature and soil water avail... ...

Genetic gain of Valenciana onion populations developed in the Brazilian Semi-Arid region. The aim of the present study was to estimate the genetic improvement in the last recurrent selection cycles applied in two Valenciana onion populations in Petrolina, PE. The experiments were carried o... ... Repository: BDPA Publication year: 2017
Identification of maintainer lines and evaluation of experimental hybrids derived from a Brazilian tropical onion population.. The four to five-fold price of onion hybrid seeds accounts for the wide use of open pollinated onion populations in Northeastern Brazil. Here we report the identification of maintainer and male-steril... ... Repository: BDPA Publication year: 2012
Onion storage in sterilized new plastic crates compared to storage in old wooden boxes. The United States Food and Drug Administration?s (FDA) proposed water rules to implement the Food Safety Modernization Act (FSMA). The FDA has proposed that plastic totes be substituted for wooden bin... ... Repository: BDPA Publication year: 2013
First report of Iris yellow spot orthotospovirus infecting onion in Santa Catarina State, Brazil. During 2017/18, 2018/19 and 2019/20 crop seasons, sudden leaf blight symptoms were observed in bulb onion crops in open fields in Santa Catarina State. Eventually, leaves exhibited whitish diamond-sha... ... Repository: BDPA Publication year: 2021
Yield of syn-1 synthetic varieties of tropical onion resulting form open-pollinated Brazilian populations. Due to technological limitations for the development of onion hybrids, first-cycle synthetic varieties (Syn1 -SV) could be an alternative to partially explore heterotic vigor. The growing areas of oni... ... Repository: BDPA Publication year: 2024
Outcrossing and heterozygosity rates in tropical onion populations. Outcrossing and heterozygosity rates are important to define genetic conservation and breeding strategies, and these estimates are quite rare for onions. This study aimed to estimate cross-pollination... ... Repository: BDPA Publication year: 2022
