    • Chromosome doubling in Paspalum notatum var. saure (cultivar Pensacola) 

      Weiler, Roberto Luis; Krycki, Karine Cristina; Guerra, Divanilde; Simioni, Carine; Dall'Agnol, Miguel (2015) [Artigo de periódico]
      Paspalum notatum is one of the most important native grassland species of southern Brazil, and the main forage source for livestock. The native ecotypes are tetraploid and have apomictic reproduction, which prevents the ...

    • Cytoembryological evaluation, meiotic behavior and pollen viability of Paspalum notatum tetraploidized plants 

      Krycki, Karine Cristina; Simioni, Carine; Dall'Agnol, Miguel (2016) [Artigo de periódico]
      This study evaluated the mode of reproduction, the meiotic behavior and the pollen viability of three tetraploid plants (2n=4x=40) originated from somatic chromosome duplication of Paspalum notatum plants. The plant WKS 3 ...

      The aim of this study was to determine the mode of reproduction of a hybrid progeny derived from intraspecific crosses of Paspalum notatum through cytoembryological analysis and use of RAPD (random amplification of polymorphic ...

    • Forage yieldof tetraploid bahiagrass hybrids 

      Ghellar Júnior, Ilson; Antoniolli, Júlio; Krycki, Karine Cristina; Lima, Mariana de Oliveira; Weiler, Roberto Luis; Brunes, André Pich; Simioni, Carine; Dall'Agnol, Miguel (2022) [Artigo de periódico]
      In Southern Brazil, much of the livestock activity is developed in native grasslands. Studies about forage traits, frost tolerance and nutritional value of native forage species there has been increasing with better results ...

    • Herbage accumulation of bahiagrass hybrids in two different environments in southern Brazil 

      Barbosa, Marlon Risso; Motta, Eder Alexandre Minski da; Machado, Juliana Medianeira; Krycki, Karine Cristina; Conterato, Ionara Fatima; Weiler, Roberto Luis; Dall'Agnol, Miguel; Simioni, Carine (2019) [Artigo de periódico]
      The native grasslands of southern Brazil have sustained livestock farming for many years; however, decline in pasture areas has led to the loss of genetic diversity of forage species.The development of forage grass cultivars ...

    • Hybrid progenies of Bahiagrass : agronomic evaluation
