摘　　要：HR132是以鄂中5号为母本,与优质低垩白恢复系绵恢725杂交,F2代选单株为母本,再和扬稻6号复交选育而成的优质籼型恢复系。该恢复系糙米率、直链淀粉、垩白粒率、垩白度、整精米率等多个指标达到国标一级标准,而且花粉量充足。HR132, deriving from the multiple cross of E-Zhong 5/Mianhui 725（a restorer with low grain chalkiness and good grain quality）//Yangdao 6, was a new indica restorer with good grain quality. It reached first class national standard in the major quality traits, such as brown rice rate, amylose content, low chalky grain rate, chalkiness degree and high head rice rate. It also had heavy pollen load.
