Cytological studies in Saccharum and allied genera. VIII. F2 and BC1 progenies from 112- and 136-chromo-some S. oflicinarum x S. spontaneum hybrids
Bot. Gaz 124: 186-90
"Pollen mother cells of 112-chromosome (2n + n) Saccharum officinarum x S. spontaneum hybrids usually showed 56n or 55n + 2I. Tri-valents also occurred. Pollen mother cells of 136-chromosome (2n + n) S. officinarum x S. spontaneum hybrids showed a range of 66II + 4I to 61II + 14I. 2. "Chromosome numbers in an F2 progeny from a 112-chromosome F1 ranged from 2n =109 to 113. Chromosome numbers in BC1 progenies from S. officinarum x 112-chromosome F1 hybrids ranged from 2n = 120 to 141.
