Bahiagrass (Paspalum notatum Flugge) is one of the major forage grasses used for beef cattle production in the southern USA. Description of the reproductive characteristics of bahiagrass germplasm is needed for genetic improvement of this forage crop. The objective was to determine and compare the mode of reproduction of diploid and tetraploid germplasm of bahiagrass. Reproductive behavior was determined by embryo sac observations and a series of controlled pollination studies in the greenhouse… Expand
Bahiagrass Tetraploid Germplasm: Reproductive and Agronomic Characterization of Segregating Progeny
TLDR
Heritability estimates obtained for these characteristics indicate that selection can be successfully used for the genetic improve-ment of this species. Expand
Breeding apomictic bahiagrass (Paspalum notatum Flügge) with improved turf traits
TLDR
While mutant plants exhibited great morphological variation, the random mutations did not affect their reproductive mode, validating the use of mutagenesis in apomictic species and indicated that selection for improved turf attributes could be successfully performed with the advantage of clonal seed propagation. Expand
Reproductive analyses of intraspecific Paspalum notatum Flügge hybrids.
TLDR
Evaluating the reproductive mode and fertility of hybrid progenies resulting from artificial crosses among artificially duplicated sexual plants, selected intraspecific hybrids of the UFRGS breeding program and apomictic ecotypes of the species confirmed all plants as promising parents for future crosses. Expand
Reproduction mode and apospory expressivity of selected hybrids of Paspalum notatum Flgge
TLDR
The aim of this study was to determine the reproduction mode of selected hybrids derived from intraspecific crosses through cytoembryological analysis and to evaluate the level of apospory expres¬sivity. Expand
Doubling the chromosome number of bahiagrass via tissue culture
TLDR
Diploid bahiagrass embryogenic callus tissue was exposed to three concentrations of three antimitotic chemical agents, colchicine, oryzalin and trifluralin and the high rates of success indicate that all agents can be successfully used to double chromosome numbers in bahiAGrass. Expand
Tetraploid bahiagrass hybrids: breeding technique, genetic variability and proportion of heterotic hybrids
TLDR
The objectives were to create a second generation of hybrids by crossing sexual first-generation tetraploid hybrids and unrelated apomictic FGTH or ecotypes, determine the segregation for mode of reproduction, and estimate the resulting genetic variation and heterosis for several agronomic characteristics.

Chromosome doubling in Paspalum notatum var. saure (cultivar Pensacola)
TLDR
The objective of this study was to artificially produce polyploid cv. Expand
Seed and forage performance for an elite group of Paspalum notatum intraspecific hybrids
TLDR
There were differences among genotypes, years and seasons for most of the variables assessed, and different performances for the traits allowing different patterns of seasonal forage yield, flowering period, seed yield and quality. Expand
Seasonal expression of apospory in bahiagrass
TLDR
Cyto-embryological analysis has been used to determine the mode of reproduction in bahiagrass, a perennial warm-season grass widely used for forage and utility turf in the south-eastern US due to its persistence in sandy, infertile soils. Expand
Análises reprodutivas e avaliações agronômicas de híbridos intraespecíficos de paspalum notatum
TLDR
Evaluating an intraspecific hybrid progeny of P. notatum on reproduction mode, pollen viability and meiotic behavior and evaluating its productive potential in field trials shows hybrids with superior characteristics will go through additional stages in the breeding program and may be candidates for new cultivars.

TLDR

TLDR
