Simulation Model for Percentage of Total Yield by Fruiting Branch Based on Different Growth and Development Type of Cotton Abstract£ºField investigation was conducted in Huarong County , Anxiang County , Datonghu District and Li County of Hunan Province from 2004 to 2005 to analyze the characteristic of yield constitution and the percentage of total seed-cotton yield by fruiting branch according to different types of growth and development of transgenic hybrid cotton. The different growth and development types were studied and classified into normal type, early-development and early-aging, early-development and early-maturing, late-development and late-maturing, two phase-growth. Six simulation models of percentage of total yield by fruiting branch corresponding to the different growth type were developed. Six simulation models were exponential-decrease, positive-skewness, negative-skewness, normal-distribution, double-peak and fluctuation-distribution, respectively. Test plots were conducted to study different growth and development types in the four counties and Hunan Agricultural University from 2006 to 2009. Models were validated by the data collected from test plots in different survey sites in different years. Models matched the different growth and development types well, and the simulated values agreed well with the observed values.The result showed that the model was accurate and applicable under different conditions, with the root mean square errors (RMSE) between simulated and observed values of the six simulation models varied from 0.3419 to 0.7092.
