Meiotic stability in two valuable interspecific hybrids of Brachiaria (Poaceae)

With 2 figures and 2 tables ABSTRACT: In an attempt to increase genetic variability in the genus Brachiaria, crosses were made between sexual tetraploidized accessions of B. ruziziensis and apomictic tetraploid accessions of B. brizantha (2n = 4x = 36). Among the F1 progenies, two hybrids (Hb331, ap...
