| 摘 要： | 通过选育稻米品质优的不育系,为杂交稻配组提供熟期适中、品质优的中间育种材料。从2002年开始,用江ⅡB与中21B杂交得到的保持系与金23A测交,经过多代回交转育,育成了籼型优质不育系瑞115A。其具有育性稳定、柱头外露率高、株叶形态理想、米质优、抗病、配合力强等特点。并配组育成了优质早稻新组合瑞丰优106。

| Abstract: | To provide the intermediate materials with medium maturity and high quality for the breeding of hybrid rice,the present study was conducted to breed high-quality male sterile rice lines.Since the year 2002,rice material Jin 23A was test-crossed with the maintainer line derived from Jiang ⅡB and Zhong 21B,and the testcross material was successively backcrossed for several generations,finally high-quality indica rice male sterile line Rui 115A was bred.Rui 115A showed the characteristics of stable fertility,high stigma exsertion rate,ideal plant and leaf shape,fine grain quality,strong disease-resistance and high combining ability.The new high-quality early rice combination Ruifengyou 106 was bred from Rui 115A. |
