Abstract: In order to study the resistance of soybean lines with different protein contents in RIL Jinf population to SCN4, the resistance of different lines was studied. The protein content was determined by Grain Analyzer, and the cyst volume of root system of high resistant lines and interval of protein content level were obtained. The result showed that the resistance to SCN4 race was not uniform among lines with different protein content in Jinf population, and cyst reaction was from 1.1 to 106.5, with an average of 68.6. High protein lines and low protein lines had low resistance to SCN4. Lines with prominent resistance had the protein content of 42% to 45%, cyst reaction was from 0.4 to 7, and the average was 3.14.
