Abstract:
This experiment was designed to study the nutritional composition and gossypol content of different transgenic cottonseed in China and then analyse their correlation.Samples of transgenic cottonseed of 9 main different varieties were collected and then their nutritional composition and gossypol content were determined.The result showed that:The average content of CP,EE,ADF,Ca and P of transgenic cottonseed were(27.89±1.66)%,(17.39±1.66)%,(23.34±1.14)%,(0.16±0.03)% and(0.36±0.04)% respectively,the average content of free and total gossypol were(3 970.35±1 109.45),(5 996.19 ±1 002.43)mg/kg respectively.The correlation coefficient of total gossypol and EE was 0.8721,and the regression equation of the two was y=525.162x-3 134.62(R2=0.760 5).The conclusion was:the nutritional and gossypol content of transgenic cottonseed showed big C.V;the content of free gossypol between transgenic and non.transgenic cottonseed had no significant difference;correlativity between EE content and total gossypol content was the highest.
