摘要 本文对浙江省早籼稻区域试验中多品系、多年、多点、非平衡、无重复的白叶枯病抗性鉴定数据,作了统计分析。分析结果表明,浙江省近年早籼稻区域试验,品种抗病性效应的方差最大,其次为地点×年份、品种×地点、品种×地点×年份互作效应。杭820显著比对照广陆矮4号抗白叶枯病,而G90-316、G90—280、杭8820白叶枯病抗性显著高于对照浙852。本文还进行了各参试品种抗性分析。 The bacterial blight resistance of early season indica rice varieties tested in rears'regional trial of Zhejiang Provincial was analized with unbalanced and unreplicated data derived from multivarieties and multiyear trials.The results showed that for the early season indica varieties tested in recent years'provincial trial,the variance effect of variety resistance was the most significant,followed by the interaction effects of location × year,variety×location and variety×year×location.Hang8820 had significantly higher leaf blight resistance than the control variety Guangluai 4.G90-316,G90-280 and Hang8820 were significantly resistance to bacterial blight than control variety Zhe852.In addition,the stability of bacterial blight resistance of the varieties tested was also studied.
