1·The evaluation of the lines resistant to SMV over three years it showed that the resistance was genetically stable.

抗病性鉴定结果表明，获得的抗性是遗传稳定的。

2·Primary infection source may be reduced by breeding and selecting the variety with the lower infected seedling rate of seed-borne SMV.

可以通过选育和筛选种传病苗率低的品种推广，减少本病的初次侵染来源。

3·Resistance of new soybean varieties to Soybean Mosaic Virus (SMV) were evaluated during the period from 2003 to 2005 in Jilin province.

通过2003～2005年对吉林省大豆新品种（系）大豆花叶病毒病的抗性鉴定，初步明确，吉林省新育成的大豆品种和后备材料较抗大豆花叶病毒病。

4·SMV, SCN, insects, and physiological stresses e. g. drought, salt; to study technology of resistance characterization; to study genetics of germplasm with specific resistance, etc.

研究病源物小种、株系、生物型的分化及抗性的差异反应以及抗性的鉴定技术和方法等。
