Miles, John W.Clements, Robert J.Grof, BelaSerpa, Aryno[Genética y mejoramiento de Centrosema]Genética y mejoramiento de Centrosema

Two essentials for breeding new cultivars of Brachiaria are germplasm diversity and information on basic biological aspects of major species. This paper reviews current knowledge on the cytological behavior, mode of reproduction and its inheritance, and crossing compatibility of different species...


Valle, Cacilda Borges doSavidan, Yves H.[Genetics, cytogenetics, and reproductive biology of Brachiaria]Genetics, cytogenetics, and reproductive biology of Brachiaria

Seed of six commercial Brachiaria species is extensively produced for pasture sowing. Production is restricted geographically and seasonally by photoperiodic flowering reactions. It also requires a prior control of vegetative tiller production, and therefore a reliable dry season. The necessary c...


Hopkinson, J.M.Souza, Francisco Humberto Dübbern de[Reproductive physiology, seed production, and seed quality of Brachiaria]Reproductive physiology, seed production, and seed quality of Brachiaria

Until 10 years ago, genetic improvement of Brachiaria species depended entirely on selection among naturally existing genotypes, genetic recombination being impossible because of prevailing apomictic reproduction. However, recent advances in understanding the genetics and cytogenetics of Brachiar...

Simpson, CEValls, JFMMiles, John W.[Reproductive biology and the potential for genetic recombination in Arachis]Reproductive biology and the potential for genetic recombination in Arachis

Data on the reproductive biology of three native glossoscolecid species from the Colombian Llanos are presented here. The seasonal dynamics of reproduction varied among the species considered which displayed either one or two reproductive periods per year. Cocoons were laid at different depths to...
