Success and Challenges of Commercial use of Frozen Pollen Production
The popularity of F1 hybrids is due to their vigor, uniformity, disease resistance, stress tolerance and good horticultural traits including; early ness and long shelf life and giving consistent stable yield. From the Breeder’s point of view, it is a fast and convenient way to combine desirable characters of vegetables together and also a way to control IP rights through control and protection of parent lines by Breeders. F1 hybrid seed production can be divided into hand pollinated and gene-control pollinated. The gene-control system can be due to Self-Incompatibility or Male-sterility. In the absence of gene-control system, a tedious hand-emasculation and pollination system has to be used to produce F1 seed. This method in principle is simple as it involves manual emasculation of pollen producing organs, anthers; followed by the pollination of pollen from the Male parent and preventing the other pollen from contaminating the pollinated flowers. This Male parent also can be controlled by Breeders through supplying Pollen and not the Male Parent. Frozen Pollen technology comes in hand to aid these Breeders. Pollen can be produced in the Breeder’s farms, dried, Frozen and supplied to the F1 seed Producers as and when they need pollen to pollinate their female parent. Producing & supplying Frozen pollen is a challenging job but by following proper protocols, this could be a successful way to protect Breeder’s rights.
