This modelling approach simulates the amylose content of rice grain as function of days from flowering date using a quadratic relationship.

The general equation for Indica and Japonica ecotypes (Liu et al., 2013) is given below:  

Where:

AC (%) is the amylose content of rice kernel as percentage of grain dry weight (D.W.);

daysFl (days) are the days accumulated starting from flowering date;

ai, bi, ci (unitless) are the coefficients of the equation, specific for Japonica and Indica varieties.
