벼멸구 저항성 Bph18 유전자가 벼의 수량구성요소에 미치는 영향

국문 초록 (Abstract)

벼멸구 저항성 Bph18 유전자를 가진 SR30071-3-7-23-6-1-1-1계통과 감수성인 '새누리'를 교배하여 육성한 약배양집단 192계통에 대해 벼멸구 저항성 유전자 Bph18이 벼의 수량구성요소에 미치는 영향을 검토하였다. 벼멸구 저항성 유전자 Bph18과 밀접히 연관된 7312.T4A 마커의 유전자형을 분석한 결과, 저항성 유전자형을 가진 계통은 24계통이었고 감수성 유전자형을 가진 계통은 168계통이었다. 벼멸구 저항성 유전자 Bph18은

Brown planthopper(BPH) is one of the most destructive insect pests of rice. The use of genetically resistant cultivars has proven to be a more economical, efficient and environment friendly means to combat this pest. This study was carried out to investigate the relationship between BPH resistant gene, Bph18 and yield components of rice using DH(doubled haploid) lines derived from 'Saenuri'/SR30071-3-7-23-6-1-1-1. SR30071-3-7-23-6-1-1-1 line has Bph18 gene derived from wild species, Oryza australiensis. BPH resistant gene, Bph18 shortened heading days, enlarged culm length and panicle length and reduced ratio of ripened grains of rice. The results indicate that backcrossing breeding is necessary to develop elite cultivars carrying Bph18 gene.
