摘要
由Rastonia solanacearumE.F.Smith引起的青枯病是中国及一些东南亚国家花生生产的重要限制因子。综述了近年来中国在花生青枯病的病原鉴定、抗病机理、抗性遗传规律、抗病种质鉴定发掘、抗病品种选育方面取得的研究进展及成就,并就存在的抗性品种产量较低、品质性状差、抗性鉴定费时费力、所利用抗源单一等问题进行了讨论,提出今后研究的重点在于采用多重杂交方式或借助现代生物技术引进疏枝亚种为抗源,同时要大力发掘利用野生花生抗性材料,完善分子标记辅助选择体系。
Bacterial wilt was a major biotic factor affecting groundnut production in China and several other counties in Asia. The current studies on groundnut bacterial wilt and resistance breeding were reviewed . Particular emphasis was given to recent advance to pathogen identification , mechanisms of resistance,inheritance of resistance , resource evaluation and resistant variety breeding. Some problems such as lower pod yield, worse quality, complicated resistance identification and unitary resistance origin were discussed, and the latter researches were suggested to be concentrated on expanding resistance origin by multiple hybridization or modern biotechnology or taking use of wild species resistance, the system of molecular makers assisting choice also should be perfected in the future.
