“…The chimera fruit exhibited a winged form, in spite of being carried on a stalk of M. fortalezensis, whose fruit is normally spheric ( Figure 1B). Because the outer layer of fruit normally comes off of the outer layer (LI) (Goffreda et al, 1990;Zhou et al, 2002), it was concluded that the chimera was formed in the epidermis of the cassava, M. esculenta (E). The meiotic investigation of the chimera flowering bud revealed that the chimera chromosome number was 2n = 54, which is the same as that of M. fortalezensis (Figure 2A), indicating that the formation of LII layer of the chimera was from M. fortalezensis ( Figure 2B).…”

“…Sporadic interspecific chimeras have commonly been shown to arise from adventitious shoot graft union formation of the scion and rootstock (e.g., Stewart et al, 1972;Burge et al, 2002;Zhou et al, 2002;Chen et al, 2006;Deng et al, 2007). Although no direct economic value of these chimera was determined in previous studies, these researchers foresaw the future potential of synthesizing chimeras for this purpose.…”

ABSTRACT. We provide the first report on the synthesis of a very productive interspecific periclinal chimera of cassava, with large and edible roots. The epidermal tissue of the chimera was formed by the cultivated species Manihot esculenta (E), and the subepidermis and internal tissue were formed by the wild species, Manihot fortalezensis (F). We used cytogenetics and morphological analyses to determine the origins of all tissues. These results may offer potential for the development of new lines for crop improvement based on the use of chimera composed of different combinations of wild species and cultivars.

“…Sporadic interspecific chimeras have been documented by some authors (Stewart et al, 1972;Burge et al, 2002;Zhou et al, 2002;Chen et al, 2006;Zhang et al, 2007). They arose from adventitious shoot formed on a graft union of a scion and rootstock, on field or tissue culture conditions, for different purposes, but not for formation of advantageous varieties, under plant breeding view, and with no significative economic value (Marcotrigiano and Gouin, 1984;Goffreda et al, 1990;Kaddoura and Mantell, 1991;Marcotrigiano, 1997b;Burge et al, 2002;Chen et al, 2006).…”

“…There are sporadic reports of interspecific chimeras that had arisen from an adventitious shoot formed on a graft union of a scion and rootstock (Stewart et al, 1972;Burge et al, 2002;Zhou et al, 2002, Chen et al, 2006Zhang et al, 2007). A few chimeras have also been produced by tissue culture, but they have no economic value (Marcotrigiano and Gouin, 1984;Kaddoura and Mantell, 1991;Chen et al, 2006).…”

ABSTRACT. Plant periclinal chimeras are genotypic mosaics arranged concentrically. Trials to produce them to combine different species have been done, but pratical results have not been achieved. We report for the second time the development of a very productive interspecific periclinal chimera in cassava. It has very large edible roots up to 14 kg per plant at one year old compared to 2-3 kg in common varieties. The epidermal tissue formed was from Manihot esculenta cultivar UnB 032, and the subepidermal and internal tissue from the wild species, Manihot fortalezensis. We determined the origin of tissues by meiotic and mitotic chromosome counts, plant anatomy and morphology. Epidermal features displayed useful traits to deduce tissue origin: cell shape and size, trichome density and stomatal length. Chimera roots had a wholly tuberous and edible constitution with smaller starch granule size and similar distribution compared to cassava. Root size enlargement might have been due to an epigenetic effect. These results suggest a new line of improved crop based on the development of interspecific chimeras composed of different combinations of wild and cultivated species. It promises boosting cassava production through 820
