How to carry out sugar cane hybridization?
The sugarcane cross must first check the fertility of the pollen in the flowering ears. The parents with good pollen development are generally used as male parents, and the parents with poor pollen development are generally used as female parent. Before crossing, the female parent must also be emasculated to avoid self-crossing; when the parents are crossed, they should be placed above the female parent. The male parent's pollen can easily fall on the mother's stigma, so that the hybridization can be successful; the air flow makes the sugarcane pollen drift easily. In order to avoid other paternal pollination, cross-pollination needs to use special density and breathable white cloth to create a new house for the “groom†and “brideâ€; sugar cane hybridization time generally takes 7 days, in order to increase the pregnancy rate, every morning 9 It is also necessary to manually shake the male parent at ~11:00 to allow the pollen to fall on the stigma of the female parent to increase the success rate of hybridization. Commonly used hybridization methods are: sulfite and high pressure methods.
