The FNCA 2007 Sub-Project Meeting on Insect Resistance in Orchid took place as follows;

Opening Ceremony

The Opening Ceremony began with the report on the background of Sub-Project Meeting on Insect Resistance in Orchid by Assoc. Prof. Arunee Wongpiyasatid, the Project Leader on Mutation Breeding of Thailand, and followed by the Opening Address by Dr. Surapol Patharakorn, Dean of the Faculty of Science, Kasetsart University.

Special lectures

Four special lectures were given by the invited speakers.

Special Lecture 1: "Project Review on FNCA Mutation Breeding"
Dr. Hitoshi NAKAGAWA

Special Lecture 2: "Mutation breeding for 46 years in Japan"
Dr. Hitoshi NAKAGAWA

Special Lecture 3: "Screening of resistant cultivars of Brassica crops and development of genetic markers for marker assisted selection"
Assoc. Prof. Dr.Keiichi OKAZAKI

Special Lecture 4: "Introduction to Gamma Irradiation Service and Nuclear Technology Center (GISC) "
Dr. Somchit PALAKAS, Head of the GISC.

Final Reports on Insect Resistance in Orchid by Each Country

Final Reports on Insect Resistance in Orchid were presented by the participants from Indonesia, Malaysia and Thailand.

Technical Visit

Participants made technical visits to two private orchid nurseries which were Salaya Orchid Nursery, Salaya District, Nakhon Pathom Province (Phalaenopsis nursery) and Thai Orchids Co., LTD., Damnoen Saduak District, Ratchaburi Province (Dendrobium commercial cut flower production)

General Discussion on Methodologies, Problem and Solution of the Project

1. It is needed to select at least one or two promising lines that are resistant to the thrips or mites within the time frame. The problems for orchid breeding are long regeneration and reproductive periods. Extension for another two years is required to complete this project in order to get the mutants or at least the establishment of the techniques for selection.
2. Proper screening facility to conduct artificial tests is very limited, and requires longer time to screen a large number of plants. Proper artificial screening method at flowering stage including severity index, for selecting insect resistant plants will be developed by the end of this year.

Conclusion:

Almost participants came to the conclusion that this project to be extended for another two years to be able to get mutants or at least the establishment of the techniques for selection.

Minutes :

The Minutes were discussed and agreed upon by all participants. This will be reported at the FNCA 2007 Mutation Breeding Workshop to be held in Korea.

Special Lectures

Four special lectures were given by the invited speakers.

Special Lecture 1: "Project Review on FNCA Mutation Breeding"
Dr. Hitoshi NAKAGAWA

He reviewd on the overall activities of the FNCA Mutation Breeding Project including drought tolerance in soybean and sorghum, disease resistance on banana, and insect tolerance in orchid.

Special Lecture 2: "Mutation breeding for 46 years in Japan"
Dr. Hitoshi NAKAGAWA

He reviewed on the research activities and varieties by mutation breeding conducted in Japan for 46 years. He presented the number of mutation cultivars, advantages of mutation breeding, and facilities of gamma ray irradiation in the Institute of Radiation Breeding.

Special Lecture 3: "Screening of resistant cultivars of Brassica crops and development of genetic markers for marker assisted selection"
Assoc. Prof. Dr.Keiichi OKAZAKI

He presented development of screening method of B. rapa against dark leaf spot disease by considering various factors including inoculation temperature etc., and reported quantitative trait loci of disease resistance genes, which are useful for marker assisted selection on disease resistant breeding.

Special Lecture 4: "Introduction to Gamma Irradiation Service and Nuclear Technology Center (GISC)"
Dr. Somchit PALAKAS, Head of the GISC.

He presented an introduction to GISC which includes the history and all activities conducted in the center and followed by a visit to the gamma facilities including gamma cell and gamma room.

Final Reports on Insect Resistance in Orchid by Each Country

Final Reports on Insect Resistance in Orchid were presented by the participants from Indonesia, Malaysia and Thailand (in Attachment 3). The abstract of all presentations are in Attachment 4, 5 and 6.

Technical Visit

Participants made technical visits to 2 private orchid nurseries which were Salaya Orchid Nursery, Salaya District, Nakhon Pathom Province (Phalaenopsis nursery) and Thai Orchids Co., LTD., Damnoen Saduak District, Ratchaburi Province (Dendrobium commercial cut flower production)

General Discussion and Present Status and Future Work Plan of the Project

It is needed to select at least one or two promising lines that are resistant to thrips or mites within the time frame. The problems for orchid breeding are long regeneration and reproductive periods. Extension for another 2 years is required to complete this project in order to get the mutants or at least the establishment of the techniques for selection.

Proper screening facility to conduct artificial tests is very limited, and requires longer time to screen a large number of plants. Proper artificial screening method at flowering stage including severity index, for selecting insect resistant plants will be developed by the end of this year.

Participants came to the conclusion that this project to be extended for another two years without the participation of Thailand. Participants hope by extending another 2 years we will be able to get mutants or at least the establishment of the techniques for selection.

The Minutes were discussed and agreed upon by all participants. This will be reported at the FNCA 2007 Mutation Breeding Workshop to be held in Korea.
