1999～2004年对河南省育成的460份小麦推广品种、优良品系等材料,在河南省漯河市进行了田间综合抗病性鉴定,分析病害对产量的影响。结果表明,病害与产量的关系成负相关,其中纹枯病对产量的影响最明显。另外,从参试的小麦品种(系)中选出了41份综合抗病性较好且产量较高的材料。
From 1999 to 2004, 460 wheat cultivars, fine lines and other materials bred in Henan Province were appraised in the field of comprehensive resistance in Luohe City, Henan Province, and the impact of disease on yield was analyzed. The results showed that the relationship between disease and yield was negatively correlated, and the effect of sheath blight on the yield was the most obvious. In addition, 41 wheat cultivars with better overall disease resistance and higher yield were selected from the tested wheat varieties (lines).
