The synthesis of a new cassava-derived species, Manihot vieiri Nassar*
Abstract
A new species was synthesized artificially by chromosome doubling in a hybrid. The ensuing polyploid type exhibits an apomictic nature and maintains its morphological characteristics in the progeny. It showed a frequency of multiembryonic sacs of 29% in the ovules examined, whereas sacs were absent in the diploid type.
*In honor of deceased Professor Vieira who dedicated a part of his life to cassava breeding
