广西杂交稻产量、米质及抗性综述

A review on yield, grain quality and resistance of hybrid rice in Guangxi

以2000～2005年通过广西区农作物品种审定的部分杂交稻组合为依据,从产量、米质、抗性等方面分析了广西杂交稻选育的概况,指出当前广西杂交水稻在产量、抗性、米质等方面还不能完全适应现实的需要。提出野生稻优异种质是今后杂交水稻突破性育种的必需种质,应加强对超级杂交稻的选育工作,并充分利用广西野生稻种质资源,选育适合广西生态条件的超级杂交稻组合,以丰富广西杂交稻类型,进一步提高杂交水稻的单产、品质和抗性。

The general aspects such as yield, quality and the resistance of hybrid rice in Guangxi have been studied using these hybrid rice combinations which have been certified and registered by Guangxi Committee for Crop Variety Registration from 2000 to 2005. It was pointed out that the yield, resistance and quality of hybrid rice could not fully meet with the real needs. It was put forward that elite germplasm of wild rice was essential for making breakthrough in hybrid rice breeding, and hybrid rice selective breeding should be strengthened. In order to enrich the diversity of hybrid rice type and further improve the yield, quality and resistance, super hybrid rice combinations should be selectively bred according to the ecological conditions in Guangxi by fully exploring the wild rice germplasm resources in Guangxi.
