TEST Ⅲ Intrinsic Line ANOVA The average of all the traits and grading traits in inbred lines in each decade showed extremely significant variations. The interdependence of the average of each trait and the environment was significant, while the interaction with the density was not significant. In the past 50 years, the grain yield of inbred lines, the number of panicles per plant and the number of stalk blight and major spot blight were all significantly improved. However,
