Abstract:

Abstract: Ten sorghum varieties were planted in Shanxi, Liaoning, Gansu, Guizhou and Hunan. Starch, protein, tannin and fat were tested and analyzed. The results showed that there were significant differences of the four quality traits among sorghum varieties and planting sites. Different regional test results indicated that the starch content variation was the smallest with an average of 2.59%, tannin was the largest of variation averaged 21.57%, protein and fat variation were 11.13% and 18.63%, it was higher than the starch and lower than tannins. It indicated change of starch content in different species is relatively small, while the tannin content was a great variation. There is a large choice and greater improvement potential. Analysis of the primary and secondary factors affecting the quality traits, results showed that the starch content was that interactive effects of genotype and environment were the main effects, but genotype was also great. Tannin content was that genotype was the main factors, protein content was that interactive effects of genotype and environment were the main effects, fat content was the average results of the environment, genotype, genotype × environment, because their squares percentage is closer. In the future, the introduction and breeding of species should consider these traits genotype, environment and interaction effects to enhance selection effects and production levels of the variety.
