Abstract

The genotypes studied in our present research manifested different degrees of culturability, differences that were registered also between species. From the 15 genotypes of wheat tested, at only 6 genotypes, we obtained plants with gynogenetic origin, while at sugar beet 12 from the 22 genotypes tested responded well to the experimental conditions utilized in our research. The best culturability was registered at genotypes: Fundulea 4, at wheat, Barsa, Record, CV40, CV14D at sugar beet. Due to the fact that there are significant differences between varieties, lines or hybrids, in what concern the gynogenetic ability and outturn, we underline the necessity of selection of genotypes able to respond to "in vitro" gynogenesis technique, or, their creation through repeated hybridization, the gynogenetic aptitude having a complex control polygene system, that can be gradually accomplished, with many components independently transmitted.
