Genetic gain of ‘Valenciana’ onion populations developed in the Brazilian Semi-Arid region

Abstract: 25CA10 and T811CR13 populations (510.5% and 522.1%, respectively), proving the efficiency of recurrent selection cycles. Genetic gains were nonlinear, and fluctuations may have occurred due to genetic drift.

“…However, unlike the results of the present study, Pasqual et al (2011), working with orchids in vitro, found a greater number of sheets with the use of calcium silicate. Moreover, Asmar et al (2011), working with in vitro banana, and Oliveira et al (2013), working with ornamental sunflower, found no differences in the number of leaves when applying sodium silicate and calcium. Sivanesan et al (2013) reported that different concentrations of silicon promoted increased dry matter in the aerial parts of the chrysanthemum and chrysanthemum plants.…”

“…The most recent studies examining the role of Si have been performed in flowers with post-harvest and production, such as calla (Almeida et al 2009), rose (Locarno et al 2011), gerbera (Guerrero et al 2012), chrysanthemum (Carvalho-Zanao et al 2012, Sivanesan et al 2013) and ornamental sunflower , Oliveira et al 2013). The only work examining the role of Si in ornamental plants grown in vitro has been performed in orchids , Soares et al 2012.…”

“…Lemus, I., & Lemus, D. (2009), indican que el mejoramiento genético vegetal tiene como finalidad incorporar resistencia a enfermedades, plagas y factores adversos del ambiente, así como mejorar la calidad de órganos antropocéntricos; esta especie es muy dependiente del fotoperiodo y termo periodo, por tanto es necesario adaptar variedades para mayor calidad en frutos, apariencia, resistencia a plagas y rendimiento (Quintana-Sierra et al (2005) & García-Velasco etal (2021). Una de las alternativas de mejoramiento es la hibridación basada en androesterelidad para obtener semilla hibrida; por tratarse de un diploide cuyo genoma comprende 15.300 Mpb/1C, organizado en ocho pares (2n=16) de cromosomas de gran tamaño, con una morfología bien definida para sus cromátidas y la posición de su centrómero; es una especie altamente heterocigoto, mostrando una variación fenotípica muy marcada (Silva de Oliveira et al 2017). El Perú dispone de excelentes condiciones ambientales en clima, suelo, agua para este cultivo (Ministerio de Agricultura, 2017) convirtiéndose en una ventaja competitiva para aprovechar la diversidad de regiones naturales y poder producir todo el año.…”
