Abstract
The characters associated with the quality of rice and the factors involved in the production of high quality rice as the proper transplanting time was examined at Unbong the southern alpine area from 2002 to 2004. The rice cultivars tested were Samcheonbyeo (Early maturing one), Sangmibyeo (Sub-early maturing one). The number of spikelets were increased as earlier the transplanting date in all cultivar, The ripened grain rates were highest transplanted on May 21 for Samcheonbyeo, and May 1 for Sangmibyeo. The highest head rice yield was obtained when transplanted on May 21 and May 1 for Samcheonbyeo and Sangmibyeo, respectively. The optimum transplanting dates according to maturing types with respect to the yield of head rice, ripened grain rates and rice quality were May 21 for early maturing type and May 1 for sub-early maturing type.
