水稻恢复系信丰9328的功能基因分析及应用
Functional Gene Analysis and Application of Rice Restorer Line Xinfeng 9328
摘要
Abstract
Xinfeng 9328,featuring large panicles with abundant grains and high combining ability,is an excellent restorer line of rice independently bred by Xinyang Academy of Agricultural Sciences.Among the combinations bred from Xinfeng 9328,2 combinations have been approved by the National Crop Variety Appraisal Committee,and 2 combinations have been approved by provincial crop variety appraisal committees.To explore the molecular basis of Xinfeng 9328,this study identified and analyzed its functional genes through gene chip technology.The results showed that Xinfeng 9328 pyramided a variety of excellent genes including yield-related genes(PTB1,Gn1a/OsCKX2,etc.),heading stage-related genes(Hd17/Hd3b,HESO1/OsHESO1,etc.),plant type-related genes(D2/CYP90D2/SMG11,TAC1,etc.),eating quality-related genes(Wxb),fertility-related genes(Rf3,DPL2,etc.),biotic stress-related genes(Bph3,Xa26/Xa3,etc.),abiotic stress-related genes(BET1,bZIP73,etc.),and other related genes(BOC1,NRT1.1B,etc.).The gene chip analysis results confirmed the breeding value of the restorer line Xinfeng 9328 as an excellent hybrid breeding material at the molecular level.This not only provides a molecular genetic basis for the innovation of rice germplasm resources but also offers guidance for the practice of molecular design breeding of hybrid rice.关键词
