This specification is of guiding significance for the production of hybrid pepper seed and ensuring the purity of hybrid pepper seed.展开更多
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.展开更多
