    • Agronomic characterization of paspalum atratum swallen and P. lenticulare kunth 

      Marcón, Florencia; Urbani, Mario Hugo; Quarin, Camilo Luis; Acuña, Carlos Alberto (International Center for Tropical Agriculture (CIAT), 2018-05-31)
      Paspalum atratum and P. lenticulare are perennial grasses, native to South America. The objective was to evaluate seasonal growth, frost tolerance, cattle preference, nutritional characteristics, seed yield and germination ...

    • Diversity in apomictic populations of Paspalum simplex Morong 

      Brugnoli, Elsa Andrea; Urbani, Mario Hugo; Quarin, Camilo Luis; Zilli, Alex Leonel; Martínez, Eric Javier; Acuña, Carlos Alberto (Crop Science Soc Amer, 2014)
      Paspalum is considered a genetic model for studying the sources of genotypic variability and breeding techniques in apomictic plants. Pas­palum simplex is a warm-season forage grass that well represents the genus since it ...

    • Diversity in diploid, tetraploid and mixed diploid-tetraploid populations of paspalum simplex 

      Brugnoli, Elsa Andrea; Urbani, Mario Hugo; Quarin, Camilo Luis; Martínez, Eric Javier; Acuña, Carlos Alberto (Crop Science Society of America, 2013-07)
      The tetraploid cytotype of Paspalum simplex has a wide geographical distribution and reproduces by apomixis, while the diploid grows in a restricted area in northern Argentina and behaves as cross-pollinated. The objective ...

    • Genetic and morphological characterization of Acroceras macrum Stapf 

      Ferrari Usandizaga, S. C.; Brugnoli, Elsa Andrea; Weiss, A. I.; Zilli, Alex Leonel; Schedler, Mara; Pagano, E. M.; Martínez, Eric Javier; Acuña, Carlos Alberto (Wiley, 2014-04-03)
      Acroceras macrum is a warm-season grass used for pastures, and it has high nutritive value. The scarce genetic and reproductive information about this grass is limiting its breeding for forage. The objective of this research ...

    • Genetic relationship among paspalum species of the subgenus anachyris : taxonomic and evolutionary implications 

      Zilli, Alex Leonel; Hojsgaard, Diego Hernán; Brugnoli, Elsa Andrea; Acuña, Carlos Alberto; Honfi, Ana Isabel; Urbani, Mario Hugo; Quarin, Camilo Luis; Martínez, Eric Javier (Elsevier, 2014-10)
      Paspalum is one of the most important genera of the Poaceae family due to its large number of species and diversity. The subgenus Anachyris comprises six species mainly from South America grouped together by sharing rare ...

    • Genetic transfer from several apomictic tetraploid paspalum species to an elite group of sexual plants 

      Novo, Patricia Elda; Acuña, Carlos Alberto; Urbani, Mario Hugo; Galdeano, Florencia; Espinoza, Francisco; Quarin, Camilo Luis (Crop Science Society of America, 2020)
      Basic findings from classical genetic studies are available for exploiting apomixis in the breeding of several forage grass genera. Most Paspalum species are multi- ploid with a sexual diploid cytotype and conspecific ...

    • Harnessing apomictic reproduction in grasses : what we have learned from paspalum 

      Ortíz, Juan Pablo Amelio; Quarin, Camilo Luis; Pessino, Silvina Claudia; Acuña, Carlos Alberto; Martínez, Eric Javier; Espinoza, Francisco; Hojsgaard, Diego Hernán; Sartor, María Esperanza; Cáceres, María Emilia; Pupilli, Fulvio (Oxford University Press, 2013-09)
      Background: Apomixis is an alternative route of plant reproduction that produces individuals genetically identical to the mother plant through seeds. Apomixis is desirable in agriculture, because it guarantees the perpetuation ...

    • Heterosis and expressivity of apospory in tetraploid bahiagrass hybrids 

      Zilli, Alex Leonel; Brugnoli, Elsa Andrea; Marcón, Florencia; Billa, M. B.; Ríos, Esteban Fernando; Martínez, Eric Javier; Acuña, Carlos Alberto (Crop Science Soc Amer, 2015)
      Breeding procedures developed for apomictic species are based on the idea of fixing superior hybrids by apomixis. However, scarce information is available about the occurrence of heterosis in apomictic hybrids. The objective ...

    • Hybridization and heterosis in the plicatula group of paspalum 

      Novo, Patricia Elda; Acuña, Carlos Alberto; Quarin, Camilo Luis; Urbani, Mario Hugo; Marcón, Florencia; Espinoza, Francisco (Springer, 2017)
      Most forage cultivars released for thegenus Paspalum belong to a section named Plicatula.The species of Plicatula are mostly apomictic andconsequently the genetic diversity is locked for theirgeneticimprovement. The ...

    • Identification of Genes Related to Endosperm Balance Number Insensitivity in Paspalum notatum 

      Depetris, Mara Belén; Acuña, Carlos Alberto; Pozzi, F. I.; Quarin, Camilo Luis; Felitti, Silvina Andrea (Crop Science Society of America, 2018-02)
      The endosperm balance number (EBN) theory states that genomic contribution ratio should be kept at maternal/paternal (m:p) ratio for normal endosperm development. However, the endosperm formation in apomictic Paspalum ...

    • Registration of ‘Boyero UNNE’ Bahiagrass 

      Urbani, Mario Hugo; Acuña, Carlos Alberto; Doval, D. W.; Sartor, María Esperanza; Galdeano, Florencia; Blount, A. R.; Quesenberry, K. H.; Mackowiak, Cheryl L.; Quarin, Camilo Luis (Crop Science Society of America, 2017-01)
      ‘Boyero UNNE’ (Reg. No. CV-5, PI 676021) bahiagrass (Paspalum notatum Flüggé) was registered with the National Register of Plant Cultivars and the National Register of Property for Plant Cultivars, Ministry of Agriculture, ...
