Abstract

Sanho is a new japonica rice cultivar with brown pericarp color (Fig. 1). This cultivar was developed from the cross Ilmibyeo//Ilmibyeo/Pyeongtaekaengmi 4, where the recurrent parent Ilmibyeo is a japonica cultivar with high eating quality, and the donor parent Pyeongtaekaengmi 4 is a japonica weedy rice from Korea. The preliminary and replicated yield trail on Sanho was carried out at Yeungnam University in 2001, 2002 and 2003, and the local adaptability test was carried out by the National Seed Management Office, Korea, in 2004 and 2005. This cultivar was registered as variety Sanho in 2006. Sanho has about 125 days growth duration from transplanting to harvesting. This cultivar has short stature with 75cm of culm length. The milled rice yield of Sanho is about 5.07 MT/ha under standard fertilizer level of the ordinary transplanting cultivation. Amylose content of this cultivar is 19.5%.
