Hibiscus rosa sinensis has a good response from people due to its medicinal and aesthetic
values. Since it is a bisexual and complete flower, it still needs deep observation of flowering
stages to identify the best stage for breeding purposes and genetic improvement of the crop.
This experiment was carried out by three male and female parents in BCKV, Mohanpur, West
Bengal. Flowers from selected varieties were plucked at five different stages in the morning
hours, and each part of the flower was carefully separated for further observation. The report
of this research reveals that the Versicolor Pin Wheel variety shows good pollen parent
features in each stage, especially in the after-senescence stage (stamen length: 1.385cm,
anther amount: 108.13 cm, and pollen viability: 95.11%), while in the Brilliant variety it was
less. Regarding seed parent, the variety that has less style and style arm length (Agni: 7.43cm
and 3.93mm), more ovary length and diameter (Cinnamon Girl: 11.817 mm and Double
Peach: 8.7 mm), a higher percentage of ovule development and stigma diameter (Double
Peach: 91.33% and 3.157 mm), and more stigma receptivity (Cinnamon Girl: +++++) at the
end of the flower is considered a suitable one. From this report, breeders can select a variety
at the perfect stage of flowering for their breeding program.
