Origin, evolution and strategies for the genetic improvement of physalis

ABSTRACT: Physalisperuviana L. (physalis) has significant economic potential by virtue of the unique flavor its fruit. However, productivity Brazilian plantations is low because limited number varieties or cultivars available. The main obstacle in selection superior genotypes lack information about genetic variability within- and between- populations basis that likely resulted from evolutionary, domestication processes natural artificial populations. Physalis currently cultivated Brazil tetraploid, such polyploidy may have led to reproductive isolation species, preventing occurrence intraspecific hybridization. Moreover, derive a common gene pool undergone long process carried out empirically farmers. In Colombia other Andean countries there are wild exhibit diversity which; although, fundamental for conservation development with agronomic traits. order create expand physalis, breeders employed various strategies including induction mutation, chromosome duplication, interspecific Furthermore, production double haploid lines vitro anther cultures shown good results hybrids. mutant and/or hybrids obtained using these methods association those wide genomic can generate
