Apomixis is the predominant reproduction method in polyploid species of the genus Paspalum.
An evaluation of variability in the expression of forage characteristics of interest and of the genetic diversity of ecotypes and hybrids of different species of the genus Paspalum by means of a meta-analysis enables the comparison of data from different trials, thus increasing the number of ecotypes, hybrids, and repetitions evaluated.
Data were obtained from studies conducted between 2002 and 2014 by the Department of Forage Plants and Agrometeorology of the Universidade Federal do Rio Grande do Sul, in which the forage characteristics of ecotypes and hybrids of the genus Paspalum were evaluated.
As criteria for inclusion in the database, the studies had to have been conducted in Rio Grande do Sul with ecotypes and/or hybrids of the genus Paspalum in plots, free from animal grazing for two agricultural years and total dry mass production (TDMP), leaf dry mass production (LDMP), and stem dry mass production (SDMP) had to be determined by means of cuts and expressed as kg of DM per hectare per year (kg DM [ha.
2015) analyzed the agronomic ecotypes and hybrids of the genus Paspalum (individual plants) and reported that the relative variability contribution of TDMP to genetic divergence was 46.
In the genus Paspalum, the absence of antipodal cells usually indicates aposporous sacs.
Findings from this study demonstrated the cytological diversity within the genus Paspalum.
