25 Jul Hybrid seed production technique of Okra
भिण्डी की फसल में संकर बीज का उत्पादन करने की विधि। Okra commonly known as ‘bhendi’ or lady’s finger is native of tropical Africa, Okra is widely cultivated in Andhra Pradesh, West Bengal, Bihar, Orissa, Maharashtra, and Gujarat are important okra producing states of India. Okra belongs to family Malvaceae with 2n=8x=72 or 144 chromosomes and is polyploidy in nature. It is often pollinated crop. Hybrid Seed Production of Okra The most productive and desirable hybrid seed obtained from the female parent when there is a perfect coincidence of stigma receptiveness and pollen viability. Pollination The transfer of pollen from male parent to female parent is called as pollination. The just opened flowers were picked from the male parent in a separate brown paper pockets and used for crossing of emasculated flowers. Different colour thread was tied to the pedicel of the crossed buds for easy identification. Pollination was carried out daily between 8-00 am to 4-00 pm. The crossing was carried out for a period of eight weeks from the initiation of flowering and avoid the selfed seeds in the hybrid. Therefore, time of pollination and ratio between female to male flower crossing is to be optimized to get increased seed set and yield in female parent of bhendi.
