To select appropriate Korean varieties in Myanmar, a serial experiments using rice varieties developed in Korea were conducted for 2 years, 2014 and 2015. Among the yield components, panicle number per hill of Shwe Thwe Yin, Myanmar variety, was 14, 19, 17 for 2014 dry season, 2014 wet season and 2015 dry season, respectively, which are 6, 1.3 and 5 panicles more than that of Korean varieties. The grain number per panicle, the ripened grain rate, 1,000 grain weight and yield of Korean rice varieties higher than that of Shwe Thwe Yin, Myanmar variety, at 2014 dry season and wet season. However, grain numbers per panicle, ripened grain rate of Shwe Thwe Yin were similar to that of Korean varieties, the yield of Myanmar variety was higher than yield of Korean varieties, at 2015 dry season. And to study the wide area adoptability, korean rice varieties and Shwe Thwe Yin were tested for 2 years, 2014, 2015 and 3 regions, the yield of Hanareum, Hangangchal 1 and Dasan 2 were higher than the yield of Shwe Thwe Yin and the regional variation of these korean varieties lower than that of Shwe Thwe Yin at 2014 wet season. Dasan 2 and Hangangchal 1 were selected as promising rice varieties in Myanmar.
