Table 12. (Continued). Area Technology Status R&D Gaps Water relations and fruit development of different banana cultivars are not known. Crop protection IPM for Bugtok, Sigatoka, and Field evaluation of available IPM banana bunchy top is available. techniques is needed. IPM for fusarium wilt, nematodes, thrips, weevils, beetles, weeds, other leafspot diseases, and other emerging pests/ diseases need to be studied. There is limited information on identity, biology, and ecology of pests and diseases. Cropping system · There is lack of new planting schemes for monocropping and intercropping systems. Postharvest System Delayed/enhanced ripening Proper postharvest handling technology technology is available. of major cultivars is lacking. Harvesting index for Cardaba Information on maturity indices of was developed. local cultivars is lacking. MA storage is available. Packaging and transportation system is poor. Product and quality standard for local cultivars is lacking. Postharvest treatments to get rid of pests and diseases are inadequate. Processing and Utilization Village-level processing is Processing facilities in production available for chips, sauce, areas are lacking. puree, strings, frozen turon, New high value and novel processed pinoy fries, and wine/vinegar. products and utilization of by-products are lacking. Standards for consistent quality of processed products are lacking. Socioeconomics and Marketing There is absence of economic assessment of different technologies generated for banana. There is lack of timely market information and intelligence for fresh banana and banana chips. Marketing strategies for selected banana varieties and their products are lacking.

Table 13. Major R&D problems on mango. Area Technology Status R&D Gaps Preproduction Variety Eight registered Carabao Improved Carabao variety with better strains are available. fruit quality (size, color, Varietal identification is not peel thickness), longer shelf fully established. life, and resistance to adverse environmental conditions is lacking. The eight registered Carabao strains have not been tested in different locations. Alternate variety for export is lacking. Further verification of procedures for varietal identification need to be studied. DNA fingerprinting of varieties and strains needs to be done. Planting materials Certified planting materials Present method of propagation (cleft are available. grafting) is wasteful of scion materials. Knowledge on the best rootstocks is lacking. Certification and accreditation system of mango nurseries (D) is poor. There is lack of supply of quality planting materials (grafted) (D). There is no concerted effort to establish scion groves (D). Production Planting density Technology on how to manage high density planted trees is lacking. Training and pruning Pruning technique is not fully Technology on how to properly train established. young trees and prune mature trees is lacking. Nutrition Recommendation is not fully Critical nutrient levels on Carabao mango established. leaves are not yet established. Nutrient management in relation to tree phenology is not yet established. Deficiency symptoms (leaves) and physiological disorders (fruits) are not yet studied. Nutrition and fruit development relationship are not known. d. Water relations Recommendation is not fully Optimum water requirement based on established. tree phenology is not known. Water relations and fruit development are not known. 24 ............................................................................................................. R&D Status and Directions
