H. aBreeding Panicum maximum in Brazil. 1. Genetic resources, modes or reproduction and breeding procedures.h[electronic resource] c1989 aABSTRACT - Apomixis is widely distributed among tropical forage grasses, and has long been merely regarded as an impediment to breeding. Panicum maximum is presented as the first opportunity for Brazilian geneticists to develop and test original breeding schemes adapted to an apomictic species. A large and representative germplasm of P. maximum has been introduced and is currently being evaluated. Basic knowledges on biology and reproduction are also available, which demonstrate an easy manipulation of apomixis and sexuality. Several limiting traits have already been detected during evaluation, which justify breeding attempts. An ideal scheme is given to transfer new qualities to already selected varieties. aApomixis aBrazil aForage grasses aGenetic improvement aPlant genetics aTropical grasslands aTropical pastures aMelhoramento Genético Vegetal aPanicum Maximum aReprodução aBrasil aTropical grass breeding1 aJANK, L.1 aCOSTA, J.
