A New High-quality, High-yielding and Lodging Tolerant Rice Cultivar “Kwanganbyeo” Adaptable to Direct Seeding

Abstract

Kwanganbyeo is a japonica rice variety developed from the cross between Namyang 7 and SR14779-HB234-31, anelite line derived from the cross between Cheonmabyeo and Aichi 37 at the National Crop Experiment Station, RDA, and washi-tecture and light-dark gren leaf color. It has good panicle shape with rare awn ocurrence, having 103 spikelets per panicle. Milledgrain shape is short and bold with translucent colors, characteristics of non-glutinous endosperm grain. This variety is moderateresistant to leaf blast and highly resistant to stripe virus while susceptible to other diseases and insect pests. The milled rice yieldsof Kwanganbyeo is 5.08 MT/ha at direct-seeding culture and 5.43 MT/ha at transplanting culture, respectably, in the local adapt-ability test for three years. Kwanganbyeo would be adaptable to middle and southern plain areas in Korea.
