Abstract: For many decades, animal production in southern Brazil has been based on native forage grasses. Paspalum notatum Flügge (bahiagrass) is one of the most frequently used native grass in southern Brazil. The native germplasm of P. notatum is tetraploid and displays apomictic reproduction; hence, chromosome doubling of sexual diploid accessions is required to facilitate hybridization. The main goal of this study was to evaluate forage production and other agronomical evaluation of P. notatum intraspecific hybrids … Show more

“…Pensacola were subjected to N fertilization levels of 0, 60, 120, 240 and 480 kg N ha -1 . The apomictic hybrids evaluated were derived from artificial hybridizations performed by Weiler et al (2018), who used tetraploids artificially polyploidizated using colchicine obtained from IBONE (Instituto de Botânica del Nordeste, Corrientes, Argentina), specifically genotypes Q4205 and Q4188, as female progenitors (Quarín et al, 2003); and native ecotypes of Rio Grande do Sul 'André da Rocha' and 'Bagual' as male progenitors. The hybrids assessed were named B26 and B43 (Q4188 × Bagual) and C22 and C9 (Q4205 × André da Rocha).…”

“…The grass genus Paspalum is an important forage constituent in natural grasslands in South America (Chase, 1929), and its center of diversity covers a wide range of ecological zones in Argentina, Uruguay, and southern Brazil (Zuloaga & Morrone, 2005). Paspalum species have been genetically improved in the United States, Argentina, and Brazil with the aim of generating forage cultivars for subtropical regions (Acuña, Blount, Quesenberry, Kenworthy, & Hanna, 2009; Aguilera, Sartor, Galdeano, Espinoza, & Quarin, 2011; Weiler et al., 2018). Plicatula group is a taxonomic informal category within the genus Paspalum (Chase, 1929), and its species comprise different ploidy levels ranging from sexual diploid to apomictic polyploid cytotypes (Novo et al., 2016).…”

“…As a general rule for the genus, a large diversity is observed for agronomic traits as a result of crossing sexual and apomictic genotypes [ 13 ]. Heterosis for traits of interest, such as forage yield and cold tolerance, have been repeatedly reported in P. notatum [ 72 , 73 , 75 , 134 ] and for interspecific hybrids between P. plicatulum and P. guenoarum [ 70 , 135 ]. An apomictic hybrid of P. notatum identified as upright and fast-growing was recently released as a forage cultivar named Boyero UNNE, resulting from a collaborative research between the University of Florida and the National University of the North-East, Argentina [ 136 ].…”
