The field experiment under medium fertility soils indicated that the maize varieties was almost as normal distribution, 22 maize inbreds were selected to study genotypes of high phosphorus efficiency. The result showed that the maize's bio-mass and grain yield were significant. According to the integration index of the low P endurance and variety adaptability, four breeds with high phosphorus efficiency were selected and their names were Jiao51, Su37, 5311,035-6. According to Date Proceeding System analyzing, shoot dry weight, root/brown ratio, leaf areas index could be regarded as important screening indexes, their accumulative contribution rate is 95%,The accumulative contribution rate of P concentration, P uptake efficiency and P utilizing efficiency was less than 5%,It was difficult to regard them as screening indexes of maize genotypes of high phosphorus efficiency.
