摘　　要：选用具有代表性的辽粳系列8个水稻品种,通过对不同品种抗逆性生理进行研究。结果表明,辽粳系列品种的抗病性均好于对照品种,但不同品种在不同地区的抗病性不同,其一与不同地区不同生理小种有关,其二与不同地区的施肥水平、栽培措施有关。为此,新品种的推广,除了良种良法配套以外,还应根据各稻区的生理小种变化情况,注重品种的区域布局和适时更新换代。A study on diseases resistant physiology of 8 typical rice varieties from Liaojing series was carried out. The results showed that disease resistance of Liaojing series of rice varieties was higher than that of the control. The level of resistance was different in different area, which was caused by both strains of pathogen and culture methods possibly. The results suggest that varies of strains of pathogen in different areas should be considered when new varieties were popularized besides cultural methods. The varieties also should be renewed in time.
