| 摘 要： | 紫兴05A是以野败型籼稻不育系嘉浙A为母本,嘉浙B/嘉红B的F4代优质株系为父本杂交,经连续回交转育而成的大穗型早籼不育系。其不育株率达到100%,花粉不育度99.99%,套袋自交不育度99.94%,具有大穗、米质较优、配合力强、中抗稻瘟病等特点。2005年通过浙江省科技厅技术鉴定。

| Abstract: | Zixing 05A is a new indica CMS line with large panicles and good quality.It is developed by crossing Jiazhe A to a selected F4plant from the cross of Jiazhe B/Jiahong B,followed by successively backcrossing to the corresponding selected paternal plants.It has a complete male sterility with 100% of sterile plants,99.98% of pollen sterility and 99.94% of spikelet sterility and is characteristic of large panicles,better grain quality,high combining ability and medi-um blast resistance.In 2005,it was technically identified in Zhejiang Province. |
