| Abstract: | Gui A,developed from crossing 95A to Guizhan and successively backcrossing its filial male sterile plants to Guizhan by the Agricultural Development Center of Guangxi University,is a new indica CMS line with super large panicles(more than 250 spikelets per panicle).It showed stable and complete male sterility,vigorous stigma with high exsertion rate,high outcrossing rate,easy to multiply and produce its F_1 hybrid seeds.Furthermore,it had tall and thick stems with good lodging resistance,fine grain quality,good restorability and high combining ability.In October,2003,it was technically identified in Guangxi. |
