摘要
本文讨论了我国南方稻区和江西省稻区区域试验中抗病性鉴定工作不足之处，并提出了４点改进建议：（１）产量因素鉴定和抗病性鉴定应区别开来，各自按自身要求选用对照品种．（２）多点人工接种鉴定和自然诱发鉴定并举，以抗性幅度说明品种的抗性；（３）抗白叶枯病性鉴定可用强致病力菌株接种；（４）产量因素试验田块的纹枯病可用药剂防治。
This paper first pointed out the shortcomings of the disease resistance identification forthe new rice cultivars in the regional test in South china and made four pieces of suggestions:1.theidentifications for yield and disease resistance should be carried out,respectively,with its own checkcultivars;2.the identifications by artificial inoculation and by natural nurseries in many regions shouldproceed at the same time and the resistence range might be taken as the index of the disease resistance;3.the virulent strains of Xanthomones campestris pv. oryzae could be used for inoculation to identify theresistance of rice to leaf blight;4.the sheath blight should be controlled by fungicides in the test fieldfor yield factors.
