摘要
Chuanxiang No.2058 is a new combination of three-line late indica hybrid rice bred based on sterile line Chuanxiang 29A and restorer Qiannanhui No.2058. In order to promote its application, seed production techniques of Chuanxiang No.2058 were explored during 2009-2010. The research detailed the seed production tech- niques from selection of seed production bases, rational arrangement of sowing gap stage, seedling cultivation in different stages, scientific arrangement of male/female parents, management of fertilizer and water, adjustment of florescence, artificial pol- lination, comprehensive treatment of disease and pest damages, and timely control- ling of abnormal and poorly-qualified rice.
川香2058是用优质香型不育系川香29A与自选优质高配合力恢复系黔南恢2058组配选育而成的迟熟籼型三系杂交水稻新组合。为促进该组合在生产上的应用,于2009~2010年在贵州省岑巩县对川香2058的制种技术进行了探索。在介绍了川香2058父母本特征特性的基础上,从制种基地选择;合理安排播差期;采用分段式育秧;科学安排父母本行比;统筹肥水管理;巧用激素调整花期;做好人工辅助授粉;综合防治病虫草害;及时除杂除劣,确保种子质量等方面阐述了川香2058的制种技术。
