Abstract:

The soybean cultivar Yudou No. 25 was sown at different dates in 5 locations of Henan Provincein 2001 and 2002. One hundred and nine samples of soybean fat content and 38 ecological factors were re-ceived. The stepwise regression was used to screen the correlated factors, which significantly affected fatcontent of soybean. Results showed that :the less sunshine hours, higher mean temperature, more rainfalland higher diurnal temperature variation from seed-filling to maturing were better for fat accumulating ,and higher mean temperature it emerging , more rainfall in blooming and poding were suitable for fat accu-mulating ;the higher total nitrogen and total potassium , lower sulfur were fit for fat forming ;in the rangeof pH 6. 95 to7. 89, higher pH 7. 89 was the best value for fat forming ;the fat content would not be affect-ed by rest ecological factors in the range of this test.
