A new Middle-late Maturity rice cultivar with Excellent Grain Quality “Hopyeongbyeo”

Abstract

Hopyeongbyeo is an anther culture derived Japonica rice (Oriza sativa L.) cultivar from the cross between Hitomebore and Hwajinbyeo by the rice breeding team of Honam Agricultural Research Institute (HARI), NICS, RDA, in 2003. This cultivar has a about 126 days growth duration from transplanting to harvesting. The short and round grain shape of Hopyeongbyeo is translucent with non-glutinous endosperm. Amylose content of rice grain is about 17.8% and high palatability of cooked rice compared with Nampyeongbyeo. This cultivar shows resistant to bacterial blight pathogenes of K1. The milled rice yield of Hopyeongbyeo is about 5.13MT/ha at ordinary transplanting culture in the local adaptability test. Hopyeongbyeo would be adaptable for the southern plain area of Korea.
