Reproductive analyses of intraspecific Paspalum notatum Flügge hybrids. [PDF]

Crop Breeding and Applied Biotechnology, 2020
Abstract Paspalum notatum is an important forage native to Southern Brazil and one of the most promising fodder species in terms of productivity, quality, resistance and growth speed. The objective of this study was to evaluate the reproductive mode and fertility of hybrid progenies resulting from artificial crosses among artificially duplicated sexual

Multivariate analysis reveals genetic diversity in Paspalum notatum Flügge [PDF]

Revista Brasileira de Zootecnia, 2021
ABSTRACT The objective of this study was to evaluate 94 Paspalum notatum genotypes over two growing seasons to estimate genetic dissimilarity through agronomic traits and the distance between genotypes. This information is used to create an ideotype from the best averages obtained for the set of characteristics evaluated.

Variation in carbon sequestration in response to water limitation in a diverse panel of switchgrass genotypes. [PDF]

J Environ Qual
Abstract Switchgrass (Panicum virgatum L.) has been identified as a “model” herbaceous species for bioenergy production by the United States Department of Energy. Switchgrass can provide several ecosystem services, including biodiversity support, soil erosion control, runoff filtering, and reclamation of marginal land.

Small RNA-seq reveals novel regulatory components for apomixis in Paspalum notatum. [PDF]

BMC Genomics, 2019
L'apomixie est considérée comme une déviation évolutive de la voie sexuelle et reproductive conduisant à la génération de descendants maternels clonaux par les graines. Des preuves récentes provenant d'espèces modèles et non modèles ont suggéré que ce trait pourrait être modulé par des mécanismes épigénétiques impliquant de petits ARN (ARNs).

Inheritance of Apospory in Bahiagrass, Paspalum Notatum

Hereditas, 2004
Previous studies on the inheritance of aposporous apomixis in bahiagrass showed a wide range of segregation ratios in crosses involving sexual and aposporous apomictic plants. The F1 progenies were classified through a visual progeny test carried out on few F2 plants.
