THE BREEDING PROCESS 1. Stalks of sugarcane whose arrows are ready for pollination are cut in 12-foot lengths and piled on a special truck provided with a container of a weak acid solution where the cut stalks are immersed. 2. The stalks are then lined in a temporary rack where they are properly labeled. Their ends are immersed in plastic buckets containing a weak acid solution to maintain freshness throughout the breeding period. Some of the collected crosses are used in the open biparental crosses where the morther and the father are known. 4. Others are used in the closed biparental crosses where the purity of the mother and the father are ensured by a covering known as the breeding lantern. 5. The arrows are maintained in their respective crossing racks for 10 days to complete the fertilization process. They are then transferred to the ripening racks for another 10 days after which they are collected. 6. The collected sugarcane seeds are bagged and dried in a dehumidified romm for 3 to 4 days. 7. The sugarcane seeds are stripped off their branches after drying. 8. A germinating medium of mill ash and filter cake is prepared. This is subjected to heat sterilization for 1 hour to kill all disease pathogens. 9. The seeds are sown in seedling flats which are kept moist at all times, and covered with a black plastic sheet to hasten germination. 10. Two-week old seedlings will be thinned out and transferred to the field after 3 months.
