Studies on different breeding systems in nerium cultivars (Nerium oleander L.)

The objective of this work was to study the different breeding systems, seed viability and seed germination in four nerium Cultivars (Nerium oleander L.). Different breeding systems like natural open pollination, autogamy, controlled pollinations and geitenogamy were studied in two seasons. In both the season of pollination no fruit set was observed in autogamy. In case of natural open pollination both the season of pollination up to five per cent of fruit set was observed in nerium cultivars.
