The objective of the present paper was to develop a new population of the pollinator cultivar Lara from the progenies of superior genotypes kept in in vitro conditions. The monogerm hybrid cultivar Lara was developed through crosses using a monogerm male-sterile family with a narrow genetic base characterized by good combining abilities, tolerance to Cercospora and the possession of the Holly gene conferring resistance to rhizomania. The pollinator is a diploid multigerm population having tolerance to Cercospora and Rizor genes for tolerance to rhizomania. Used in the study were phenotypically superior pollinator genotypes contained in individual plants within the population. The newly developed homogenous clonal population was kept in a gene bank. A high propagation rate was obtained by stimulating axillary buds from the vegetative tissue of the infloresecence. Based on the hybrids production chatacteristics, superior pollinator genotypes were propagated vegetatively and a new population of the pollinator Lara was developed.
