Leucaena cytogenetics in relation to the breeding of low mimosine lines.
cf. F.A. 28 No. 1829.] Meiotic and mitotic chromosomes were studied in L. leucocephala and L. pulverulenta (2n = 56), L. trichodes, L. lanceolata, L. stenocarpa and accessions designated as Buitenzorg (2n = 52) and L. esculenta (2n = 104). All species appeared to hybridize freely. The 80-chromosome hybrids of L. pulverulentaXL. leucocephala were grown and studied in detail. Genetic variation in mimosine content is discussed.
