Diversity in diploid, tetraploid and mixed diploid-tetraploid populations of paspalum simplex
(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 ...
Agronomic characterization of paspalum atratum swallen and P. lenticulare kunthCaracterización agronómica de paspalum atratum swallen y paspalum lenticulare kunth
(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 ...
Transcriptome analysis of seed development in apomictic Paspalum notatum
(Ricardo Antunes Azevedo, 2015-01-01)
The seed developmental process involves various tissues with several ploidy levels and different genetic origins. Therefore, its characterisation at the transcriptome level is certainly a challenge. The hypothesis of ...
Genetic and morphological characterization of Acroceras macrum Stapf
(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 ...
Hybridization and heterosis in the plicatula group of paspalum
(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 ...
Widening the gene pool of sexual tetraploid bahiagrass : generation and reproductive characterization of a sexual synthetic tetraploid population
(Crop Science, 2018)
The improvement of bahiagrass, Paspalum notatum Flüggé, has been inhibited by reduced levels of genetic diversity in sexual tetraploid germplasm. A few experimental sexual tetraploid genotypes (ESTGs) have been generated ...
Heterosis and expressivity of apospory in tetraploid bahiagrass hybrids
(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 ...
Respuestas ecofisiológicas a la fertilización nitrogenada en genotipos tetraploides apomícticos de Paspalum notatum Flüggé
(Universidade Federal de São Carlos, 2019)
Las gramíneas megatérmicas perennes muestran una fuerte respuesta en su Producción
Primaria Neta Aérea (PPNA) a la fertilización nitrogenada (FN), sin embargo los
mecanismos ecofisiológicos que la generan aún son poco ...
Identification of Genes Related to Endosperm Balance Number Insensitivity in Paspalum notatum
(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 ...
Diversity in apomictic populations of Paspalum simplex Morong
(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 ...
