Resumen
Buffel grass is a fodder grass that reproduces mainly via apomixis. Using in vitro tissue culture in apomictic species provides alternatives that can be applied in a breeding program. The aims of this work were to establish a protocol for in vitro generation of apomictic buffel grass genotypes using anthers as explants and to evaluate the genetic stability of regenerated plants via flow cytometry (FCM). Three genotypes were able to induce embryogenic

dc.description.abstract | Buffel grass is a fodder grass that reproduces mainly via apomixis. Using in vitro tissue culture in apomictic species provides alternatives that can be applied in a breeding program. The aims of this work were to establish a protocol for in vitro generation of apomictic buffel grass genotypes using anthers as explants and to evaluate the genetic stability of regenerated plants via flow cytometry (FCM). Three genotypes were able to induce embryogenic calli in Murashige and Skoog (MS) medium supplemented with 6 mg/l of 2,4-dichlorophenoxyacetic acid. Seedling regeneration occurred in a MS medium supplemented with 0.5 mg/l napthaleneacetic acid + 1 mg/l 6-benzylaminopurin. Seedlings were derived from somatic embryos and the morphogenic process was induced using the somatic tissue of the stamens. Induction and regeneration efficiency depended on the genotype and was affected by date of tiller collection, different pretreatments or the interaction of these variables. FCM analyses in in vitro regenerated plants showed genetic instability in their nuclear DNA content. Plants with lower nuclear DNA content may indicate DNA aneuploids (8.6 %), whereas plants that had twice the value of nuclear DNA content (4.7 %) suggest in vitro polyploidization. This variation observed in apomictic genotypes provides an opportunity to obtain new variants, which may then be included as sources of genetic variability in buffel grass breeding programs. | eng |
