IN SITU DEVELOPMENT OF IN VITRO DERIVED HAPLOID AND DOUBLED HAPLOID CUCUMBER PLANTS

Haploid and doubled haploid plants are valuable materials for genetic and cytogenetic studies as well as for plant breeding purposes.
Several in situ and in vitro methods are being studied to obtain high frequencies of haploids and doubled haploids in vitro, development patterns of which appear to be similar.
It was our aim, that in case in situ development pattern is different from that of in vitro, to determine plant characteristics and some morphological features of the haploids and doubled haploids after transplanting to soil to be grown under greenhouse conditions.
Marked differences were observed and illustrated between the cucumber plants from the both ploidy level.
These differences were mainly on plant height, lateral branching, length of internodes, flowers, anthers, pollen production and fruit set.
It was also determined that some of the characteristics studied were dependent on either the open pollinated or the hybrid origin of the plants.
