| 摘 要： | 以50个自交系和24个杂交种为材料，测定其总磷、植酸磷、无机磷含量，分析不同基因型玉米子粒中植酸磷及其他形态磷含量的差异性和相关性。结果表明：不同自交系和杂交种间3种磷形态的含量均存在显著差异，植酸磷与总磷间呈正相关，与无机磷间呈弱度正相关。在低植酸玉米选育时，应该同时采用植酸磷和无机磷两个指标作为选择标准。自交系丹黄02是选育较低植酸磷、高无机磷含量杂交种的优良亲本材料。

| Abstract: | The concentration of total P, phytic acid P and inorganic P in 50 inbred lines and 24 hybrids seeds were studied, and then the difference and relationships among these P indices were analyzed. The results showed that there were significant differences in inorganic P, phytic acid P and total P among 50 inbred lines and 24 hybrids, and phytic acid P was positively correlated with total P. However, there was not obvious relation between phytic acid P and inorganic P in 50 inbred lines. Phytic acid P and inorganic P were suggested as both indicators when maize varieties with low phytic acid P and high inorganic P were developed. Among inbred lines, Dan Huang 02 was a better variety with low phytic acid P and high inorganic P content. |
