Thailand Background

Thailand, officially the Kingdom of Thailand,

formerly known as Siam.

Bangkok is capital of Thailand.

Thailand is the world's 51st-largest country.

An area of 513,000 km2 (198,000 sq mi).

Bhumibol Adulyadej (Rama IX) is the king of

Thailand.

Thailand is located in the center of peninsular Southeast Asia, 76 provinces.

Agricultural regions divided into

5 regions, namely:

1) North

Potato in Thailand is an important in the north and

northeastern part of Thailand because potato chip

consumption is an increasing rapidly.

The potato farmer income: 2,679-4,464 $US/hec

(15,000-25,000 baht/rai).

The entrepreneur required more potato production for

processing and farmer also required basic seed

production (G1) and certified seed production (G2-G3)

to support them.

DOA produced pre-basic seed (G0) and basic seed

(G1) for farmer but it not adequate.

The enterprises of potato chip are imported certified

seed >>> high unit cost and difficult for a

management system.

Farmers are stored low quality (virus, bacteria, scab

etc.) certified seed potato for planting in next

season.

The effect to the quantity and quality of potato, by

reduce the total yield and also reduce the

marketable quality.

Problem of potato production in Thailand

11

To find technology or protocol are produced high

yields, more easy, rapid, flexible, more security for

the phytosanitary quality and at lesser cost through

research and development.

The purpose of this study to find the new technology

of propagate potato plantlets by tissue culture

technique in solid media or microtubers production

by bioreactor and pre-basic seed production under

aeroponic system that improve quality and quantity

and lower costs.

How to solve the problem

Project Impacts & Recommendations

The high temperature and unsuitable fertilizer ratio are affected

to impact crops.

Potato virus are seed-borne, reduce mass production of seed

potato.

The technique of in vitro micropropagation in potato cv. Atlantic

will be done.

The technique of induce microtuber in solid and liquid media

should be develop.

The minituber production under aeroponic system should be

improves technique, lower costs and increase the farmers’

income.

Aeroponics is a soilless method for producing pre basic potato

seed.

The method can produce higher yields, easier, rapid, flexible

and more security for the phytosanitary quality.
