Descripción
Embryo rescue techniques have been used as an approach to raise hybrids from incompatible crosses. Thesetechniques have also proved to be valuable tools for maize improvement, since they allow reducing the durationof the generation cycles for speed breeding. The aim of this study was to identify an efficient embryo rescueprotocol to evaluate the response of maize (Zea mays L.) embryo culture and compare its generation time (seedto seed) with the generation time of plants obtained by mature seed germination. To this purpose, we evaluatedthe germination efficiency, in vitro protocol efficiency, and days to flowering of three advanced maize inbred linesdeveloped at the National Institute of Agricultural Technology of Argentina. A greenhouse traditional strategywas used as control. The embryo rescue technique allowed obtaining nearly four generations per year comparedto the two generations obtained in greenhouse. All the plants obtained by the embryo rescue technique weremorphologically normal and fertile. The results confirmed the possibility of using embryo rescue strategies tosignificantly reduce the duration of the generation cycles in maize.
