摘要： 经过严格的抗性鉴定筛选,发掘出6个白背飞虱抗源材料，即石崖粘、白秆糯、Nabeshi、IR64、Rathu Heenati。 经抗性遗传分析,明确了6个抗源中4个国内品种对白背飞虱的抗性遗传方式。 石崖籼和5006携带单显性抗白背飞虱基因,抗性为显性遗传;白秆糯 和Nabeshi携带单隐性抗白背飞虱基因,抗性为隐性遗传。

Abstract: Six rice varieties resistant to whitebacked planthopper(WBPH) were found by Standard Seedbox Screening Test in 18 rice varieties. Genetical analysis of resistance showed that a single dominant gene governs the resistance to WBPH in Shiyazhan and 5006, and a single recessive gene governs the resistance to WBPH in Baigannuo and Nabeshi.

Key words: genetical analysis, germplasm resource, resistance, whitebacked planthopper
