But through the introduction of improved varieties, local varieties so called landraces are now on the verge of extinction. It is a critical stage to explore, collect and conserve domestic plant genetic resources in the country for future utilization. Thus a joint rice exploration program of MAFF Genebank project and Myanmar Seed Bank was carried out in the Northern Shan State and Kachin State of Myanmar from November 16 to December 15,2000. Of the lowland rice varieties collected, 80 percent were improved varieties introduced from foreign countries in the past 3~5 years. However some landraces suitable for the eating habitat of local people or local agro-ecological conditions such as alkali soil are still remained. On the other hand, most of the upland rice varieties were landraces although improved varieties have been gradually introduced. A total of 104 varieties including landraces, improved varieties and wild rices were collected. In the landraces, a big variation was observed on grain shape, grain color, plant type, tolerance to cool weather and resistance to pests and diseases.}, pages = {67--79}, title = {ミャンマー連邦シャン州北部およびカチン州における稲遺伝資源の探索収集}, volume = {17}, year = {2001}, yomi = {タキタ, タダシ and タムラ, ヤスアキ and イリエ, ケンジ} }
