摘要

Haihui 818 is a new restorer line by cross breeding with Hua 23 S and Huahui 8131.Good plant type,high tillering ability,fine grain quality,strong restoring ability and high yield were shown in hybrid production.After artificial inoculation and field stress and molecular market-assisted selection,the results showed that rice-blast resistance genes Pi1,BB resistance genes Xa7,and brown planthopper resistance genes Bph3,Bph14 and Bph15 were pyramided together.Among its hybrids,Bo II You 818(Bo II A/Haihui 818)was approved for commercial production by Hainan Provincial Crop Variety Approval Committee in 2015.
