A New High-yielding and Lodging Tolerant Rice Cultivar “Andabyeo” with Multiple Resistance to Diseases and Brown Planthopper

Abstract

Andabyeo, a new Tongil-type rice (Oriza sativa L.) cultivar, is developed by the rice breeding team of National Cropbetween SR11532-4 and SR14502F2. This cultivar has about 115 days of growth duration from seeding to heading and is semi-dwarf (culm length 81 cm). It has erect pubescent leaves and thick stif culm with strong lodging tolerance. This cultivar has a fewtillers per hill and markedly more spikelet numbers per panicle. Andabyeo has good germinability but slightly sensitive to lowduring the ripening stage. This cultivar is considerably multi-resistance to blast, bacterial leaf blight (K1, K2), stirpe virus diseaseand insect pests. Milled rice of this variety is non-glutinous endosperm with slightly less translucency and more chalkiness com-amy-lose content and low gelatinization temperature. The yield performance of Andabyeo is 7.24 MT/ha in milled rice at ordinaryplanting cultivation of 1996~1998 local adaptability test in the low-land area of midle-Southern zone. Andabyeo may be adapt-able to ordinary transplanting in the low-land area of the middle and Southern part of Korea.
