“…These diploids, which probably present sexual reproduction, could be used for crossing between each other or even with Pensacola, without chromosome doubling. These findings would ensure sexual accessions for crossing since chromosome doubling can lead to apomixis (Quarin et al 2001, Krycki et al 2016.…”

“…In P. notatum, sexual tetraploids plant were obtained by the chromosome duplication of cultivar Pensacola (Quarin et al 2001, Weiler et al 2015, Machado et al 2017. However, in some cases, the mode of reproduction changes after duplication, and tetraploidized plants become apomictic (Quarin et al 2001, Krycki et al 2016. Quarin et al (2001) state that the apomixis gene is present at the diploid level, but it is unexpressed in the diploid plant.…”

“…Recent studies in native species of the state of Rio Grande do Sul show irregularities in meiotic behavior similar to that of crem, but with a predominance of regularity and high pollen viability in lemon grass (Elionurus muticus) (Füller et al 2015), cherry tree accessions (Eugenia involucrata) (Guerra et al 2016), and Paspalum notatum tetraploidized plants (Krycki et al 2016). According to Pagliarini (2000), irregular chromosome segregation is the most common meiotic abnormality in both cultivated and native species, being characterized by the presence of chromosomes in precocious chromosome ascension and laggard choromosome.…”

“…Mature pollen was analyzed, of which the stained grains were considered viable and wrinkled or colorless grains unviable (Singh 1993). About 1000 mature pollen grains per plant were counted in four flowers per plant (250 pollen grains per plant), following the protocol established and used (Dahmer et al 2008, Guerra et al 2013, Krycki et al 2016. The pollen viability estimate was calculated by the percentage of viable grains: number of grains considered viable divided by the total number of grains multiplied by 100 (Tedesco et al 2019).…”
