A male sterile plant of pollen abortion was discovered in Ma Wei Zhan,of Chinese native rice variety in China.Using Xie Qing Zao crossing and backcrossing,Ma Xie A has been bred. The study went on the character,flowering habits,cytological character of pollen abortion,cytoplasmic qaulity,mt DNA and COD isozymes etc.The results indicated that Ma Xie A is a new CMS type.It possesses important value in theory and in practice.Ma Xie 63,Ma Xie A/Ming Fei 63,posseses high yield,good grain qaulity and multir-resistance.It had passed the comparison experiments of both Hubei province abd national regional trial of hybrid rice in 1990 and 1991,respectively.Now Ma Xie 63 will widely plant in grain production. 中国农家品种 马尾粘 细胞质马协雄性不育系 Q321.6;Q321.8 国家自然科学基金、国家教委、国家“八五”攻关和湖北省农牧业厅资助的课题 1993-06-01 2021-04-01 6
