摘 要：本文对大豆重组自交系Jinf群体进行苗期抗旱性筛选鉴定，对筛选出的抗旱材料和不抗旱材料进行抗孢囊线虫4号小种抗性鉴定,并对其抗孢囊性和抗旱性之间的抗性关系进行分析研究。结果表明：Jinf群体苗期抗旱材料抗孢囊线虫4号生理小种的抗性远高于不抗旱的材料，长籽粒株系的抗旱性和抗孢囊性潜力大。

Abstract: The drought resistance of the soybean RIL Population named as Jinf was screened and appraised, Drought and Non-drought Resistant materials Was appraised to Cyst Nematode Race 4, and the resistance between the cyst and drought resistance were studied. The results showed: Resistant to SCN4 of drought resistant materials of Jinf Population is much higher than the non-drought resistant materials, Potential of long grain of drought resistance and resistance to cyst of potential was great.
