We studied and characterized populations PCT-4 and PCT-7 and gene pool GPIRAT-10 at the Instituto de Investigación del Arroz at rice experiment station, situated south of Jíbaro in the Province of Sancti Spíritus, Cuba, between the 1996 wet season and the 1999 dry season. We aimed not only to cha...

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...

Allogamous reproductive behavior and the demonstrated existence of ample genetic variation for a number of agronomic traits in Andropogon gayanus suggest a substantial potential for genetic manipulation of the species. Possible breeding objectives are considered and appropriate breeding methods d...

The genus Stylosanthes Sw. has provided ample germplasm for a wide variety of agroecological situations in the tropics. The most important attributes of successful Stylosanthes cultivars used as pasture or ley in the tropics are resistance to diseases, high seed yield and adaptation to poor soils...
