Abstract

Allometric growth has been widely studied as an important law in biology. In order to reveal allometric growth and its pleiotropism, a new model is proposed to map the QTL which is related to allometric growth based on the framework of functional mapping in this paper. Using this model, a soybean population of recombinant inbred lines(RIL)is demonstrated to analyze the QTLs which affect allometric growth between leaf biomass and total weight. The QTLs in the 24th linkage groups detected by this model are testified by the Logistic model to find out pleiotropism. This extended model improves the accuracy of QTL mapping and estimate of the parameters of allometric growth by means of two merits, which the dynamic traits of biological growth processes are conceived and multiple time points in the experimental data are employed.
