1. Sugar cane varieties and observationsThe general conditions <strong>of</strong> <strong>Jamaica</strong> suggest that varieties specially adapted to highphotosynthesis efficiency are desirable because they convert solar energy to accumulate totalcarbon as sugars and fiber. More specifically, <strong>Jamaica</strong> should trial varieties with characteristics<strong>of</strong> the following types:a) High total sugar varieties rather than high sucrose, since rum and ethanol do not requiresucrose as granular sugar doesb) High fiber varieties where more bagasse is needed to allow a modern cogenerationplant to run year round, including varieties with high sucrose content and salinitytolerancec) Varieties that mature early or late to allow an ethanol plant to receive feedstock over alonger period annuallyd) Varieties <strong>of</strong> sweet sorghum as a supplement to sugar cane where it can help increaseoverall pr<strong>of</strong>itability or require less water and grow in dryer areasTo develop suitable varieties, the current cane-breeding program should be expanded in orderto select those that match the changes to the products and not just to focus on good varietiesfor granular sugar, as has been the past need.The ripening period seems to be quite challenging due to the absence <strong>of</strong> low temperatures orsevere drought throughout the year. The yields found in the visited mills show that there is alot <strong>of</strong> room to increase cane yield and sucrose content, especially through the introduction <strong>of</strong>new varieties.The SIRI plots visited are a testimonial that there is a huge potential to increase production withnew varieties, but the numbers are still relatively small for future sector growth plans. Thebreeding program receives material from the West Indies Central Sugar Cane Breeding Station(WICSBS), Barbados, but this source should not be relied upon solely. Cooperation with otherbreeding programs must be initiated with priority to programs with similar weather conditionsas <strong>Jamaica</strong>. Many breeding programs around the world are willing to have agreements withother places and countries in order to develop new varieties. We recommend that <strong>Jamaica</strong>considers contacting the following breeding centers with a view to establishing a workingrelationship with at least two in addition to the current relationship with WICSBS:(1) Sugar Breeding Institute (Indian Council <strong>of</strong> Agricultural Research), Combitore, Tamil Nadu,India [www.sugarcane-breeding.tn.nic.in](2) Philippines Sugar Research Institute (PHILSURIN), Victorias City, Negros Occidental,Philippines. [www.philsurin.org.ph](3) Indonesian Sugar Research Institute (P3GI), Jalan Pahlawan No 25, Pasuruan 67126,Indonesia [www.sugarresearch.org](4) Centro de Technologia Canavieira (CTC), Piracicaba, Sao Paulo, Brazil[www.ctcanavieira.com.br]13
