    Executive summary The fourth joint workshop between AVRDC – The World Vegetable Center (AVRDC) and the Asia and Pacific Seed Association (APSA) held on 17-18 May 2010 was a time to evaluate the status of the working relationship and chart a new course for future collaboration. Twenty-six APSA members, 28 AVRDC staff, and Victoria Henson Apollonio and Guat Hong Teh, observers from the CGIAR Central Advisory Service on Intellectual Property (CAS-IP), participated in the meeting at the Center’s Headquarters in Shanhua, Taiwan. Jackie Hughes, AVRDC’s Deputy Director General for Research and Anthony Tse of the Clover Seed Co. Ltd., welcomed seed company owners, managers and scientists from Thailand, Philippines, India, China, Taiwan, and Japan to discuss issues of mutual interest with AVRDC’s management and scientists.

    Presentations and discussions were followed by a field tour. Twelve scientists presented the Center’s recent work in vegetable breeding, germplasm, biotechnology,

    gene discovery, nutrition, and plant protection. Some highlights:

    • Peter Hanson discussed the incorporation of marker- assisted selection (MAS) into the AVRDC tomato breeding program to develop tomatoes resistant to biotic stress. He noted a recent comparison of costs indicated MAS was slightly more expensive than conventional means, but can save a lot of effort in transplanting, provides much more information, and can improve the efficiency of selections.

    • Andreas Ebert presented a review of the AVRDC genebank—the world’s largest public-sector collection of vegetable germplasm, with more than 57,000 accessions from 408 countries. He emphasized the need to collect data on abiotic stress from many locations, to give more full characterization to existing lines in the collection.

    • Edwin Javier introduced genotype-environment analysis of AVRDC’s International Chili Pepper Nursery. The international nurseries provide a set of improved lines for evaluation in different countries and environments.

  • Proceedings of the 2010 APSA-AVRDC Workshop6

    • Nutritionist Ray-yu Yang gave an overview of global nutritional status, and discussed the Center’s work in developing vegetable lines with improved nutritional qualities. Breeding for nutritional content has produced tomatoes with high levels of beta-carotene, providing 3 to 9 times the vitamin A of normal tomatoes, and heat-tolerant peppers with high carotenoid and very high vitamin C content.

    • In her presentation on the development of tomato simple sequence repeat markers and their use in mapping bacterial wilt resistance, Jaw-fen Wang explained why the markers are becoming indispensable to plant pathologists: the markers are highly reproducible, inexpensive, and simple to handle; they can be used by small labs; and can differentiate homozygous and heterozygous lines.

    All twelve presentations were followed by question-and- answer sessions.

    On the field tour organized by the AVRDC Virology team, participants visited a preliminary yield trial of multiple TY tomato lines and the International Sweet and Chili Pepper Nurseries. An evaluation trial of leafy Brassicas and a cucumber yield

    trial were also toured. Tomato differentials to Phytophthora infestans races were on display in the glasshouses, and participants received a begomovirus resistance screening demonstration in the virology screenhouse.

    As always, the Center will ship seed from its collection at the request of any APSA member. APSA can help the Center’s genebank expand further by sharing lines with interesting horticultural characteristics with our Genetic Resources and Seed Unit. The Center encourages all APSA members to acknowledge the use of AVRDC germplasm in their catalogs.

    High-quality vegetables that fetch good prices in domestic and export markets—and improve incomes and nutrition for small-scale farmers—begin with quality seed. Both AVRDC and APSA will seek to increase farmers’ access to improved vegetable seed in developing and developed countries alike by building on the strong partnership that has been forged during the past four years.
