This amount was only one fifth of the investments made in mango (P171 M) and more than half in banana (P53 M) or in ornamental horticulture (more than P58 M from 1990 to 2000). These commodities, including papaya, have been accorded high priority by DOST under its Science and Technology Agenda for National Development (STAND) and by DA through its High Value Commercial Crops (HVCC) Program. Projects and Studies on Papaya With the government’s investment for papaya R&D, 43 studies were conducted from 1990 to 2003. The studies focused on varietal improvement (14), crop production and management (11), crop protection (10), biotechnology (5), postharvest handling (2), and socioeconomics and marketing (1) (Table 8). Biotechnology studies, however, got the bulk of the budget (74%) followed by studies on varietal improvement (14%). Biotechnology projects on papaya came in 1997 as part of the DOST-approved biotechnology Table 7.

From 1998 to 2003, there were five approved biotechnology studies on papaya with funding from DOST, PCARRD, and the Australian Center for International Agricultural Research (ACIAR). The support amounted to P23 M. IPB researchers solely implemented the studies to produce papaya with resistance to PRSV and papaya with delayed ripening characteristics. Varietal improvement studies on papaya mainly revolved around collection, evaluation, purification, and hybridization. About 82% of the R&D investment on varietal improvement went to papaya breeding at IPB. The papaya breeding project started in 1981 even when PRS was still unheard of (Villegas 1996). During the first phase (1981– 1990), this UPLB-funded project lost a lot of breeding lines developed because of PRS. Hence, the project objectives had to be refocused to include PRSV resistance/tolerance. PCARRD and UPLB funded the second phase from 1990 to 1995. It came up with a PRSVtolerant Sinta papaya, which is considered as an R&D milestone. DOST supported the third phase (1996–2002). This involved further breeding work that identified four promising PRSV-tolerant F 1 hybrids and adopted micropropagation as an alternative method to produce planting materials. Together with this breeding project were other projects or studies related to PRS. Almost 6% of the R&D investments were put to crop protection (vector control, virus eradication, and management strategies), while 5% went to crop production and management. In fact, DOST funded the PCARRDpackaged papaya rehabilitation and development program in Southern Tagalog and in the Bicol region where PRS had taken its toll on papaya plantations. Among the R&D efforts, postharvest handling (2%) and socioeconomics and marketing (0.05%) researches got the least budget from the total investments. PCARRD funded basic research on reducing fruit injury of the Solo papaya that is subjected to VHT. Technological Breakthroughs and Information Generated The National Agriculture R&D Network (NARRDN) has reported 13 research findings on papaya from 1990 to 2003 (Table 9). These were published in the PCARRD’s R&D Highlights and in the PCARRD-based Horticulture Information Network (HORTINET) Web site (http:// www.hortinet.pcarrd.dost.gov.ph). The research findings have generated information and technologies that give significant development or new knowledge, offer bright prospect for business, possess significant social and economic implications that need to be disseminated and validated under the actual farming situations.
