500 wheat varieties were grown and screened, and 18 of them with better characters identified in the low phosphorus, low zinc, low boron soil and in contrast with the control (applied with N, P, Zn and B). A few varieties showed able to efficiently utilize P, Zn or B in soil, and it has been demonstrated by the analysis that their roots can secrete more organic acids making the soil pH around the roots decrease. Six organic acids in the roots of four representative varieties were analysed, their contents were of difference among the varieties and had a positive correlation with the yield of the varities in low nutrition soil. All the above-mentioned provided the scientific basis of crop breeding for efficient utilization of soil nutritions.
