| 摘 要： | 对13个籼型杂交稻不育系及其保持系的异交、花器、农艺和米质等24个性状较系统地进行比较分析.结果表明,新近选育的籼型不育系趋于长颖花、长柱头、长花柱、较高的柱头外露率和天然异交率;较长、窄的剑叶和倒二叶,穗也较长;稻米的外观品质也相对较优.本文还对柱头外露率和米质性状的选育途径进行了讨论.

| Abstract: | Comparison analysis of 24 characters involving outcrossing, floral, and rice quality traits as well as sone agrocharacters were investigated in 13 cms lines and the maintainers in indica hybrid rice. The results indicated that spikelet, stigma, style, grain shape and panicle length were longer in cms lines developed in recent years than those in cms lines developed in 1970s; stigma exsertion, outcrossing rates and rice quality were improved in newly developed cmslines. The improvemeut of the stigma exsertion and rice quality of cmslines and maintainers was also discussed in this paper. |
