Abstract

“Beu Ner Moo” rainfed aromatic highland rice varieties were planted on rice terrace by hilltribe Pwakin-nyaw (Karen). The name means aromatic rice which were selected by Pwakin-nyaw farmers long time ago and still grown as a special varieties until now. Due to their impurity, pure line selection was the breeding methodology and geographical indications (GI) was the way to increase their value. There were three steps to develop Beu Ner Moo. 1) Collecting 48 Beu Ner Moo rice varieties from 4 districts of Chiang Mai including Mae Ai, Chiang Dao, Chai Prakan and Mae Chaem. 2) Purifying Beu Ner Moo rice by pure line selection according to their morphological characters and can be classified into 10 groups. Then selected only 6 groups with long grains and aroma as the rice owner described. 3) Establishing Beu Ner Moo yields database by selecting only 6 groups of Beu Ner Moo to plant and compare their yields with recommend varieties (KDML 105 and PTT1) and local varieties (Beu Chaw Me and Beu Taw Mae). Results found that the 6 selected groups had yield of 246 – 409 kilograms per rai with no significant difference among those varieties but less than PTT1 (686 kg/rai) and higher than KDML 105 (173 kg/rai). Introducing and expanding pure Beu Ner Moo varieties into Pwakin-nyaw’s rice terrace in Chiang Mai may lead to have new GI product in the future.
