| Summary, etc |
Se estudiaron el no. cromosomico y el comportamiento meiotico de Leucaena leucocephala, L. diversifolia, L. pulverulenta, hibridos F1, F2 y F3 de L. leucocephala x L. diversifolia y F1 de L. leucocephala x L. esculenta y L. leucocephala x L. shannoni. Se detecto amplia variacion intraespecifica en el no. de cromosomas de L. leucocephala y L. diversifolia, debido probablemente a la hibridacion natural. Se observaron no. cromosomicos bajos (aprox. 2n = 52 de L. diversifolia diploide), intermedios y altos (aprox. 2n = 104 de L. leucocephala y L. diversifolia tetraploide). Ocurrio lo mismo en hibridos F1 de estas 2 especies. En arboles F2 y F3 de cruces L. leucocephala x L. diversifolia diploide solo se detectaron no. cromosomicos intermedios y altos, indicando una tendencia hacia el incremento de no. cromosomicos en generaciones avanzadas, seleccionadas por su tolerancia a suelos acidos. El comportamiento meiotico fue principalmente regular en las especies e hibridos, con predominio de celulas madre del polen con solo bivalentes en la metafase. Se sugiere que ocurre solamente apareamiento intraespecifico homologo y homoeologo y, consecuentemente, los genes de cada especie presente en un cromosoma particular son transmitidos en bloques a los hibridos, con implicaciones teoricas importantes para el fitomejorador.
