Abstract: For exploring how genome expresses a trait and whether or not the gene spectrum is as a sub-sys- tem to operate, the experiment is to be taken. There are twenty-four hybrids to be made by the di-allel crossing method with the three line parents of two male sterile lines A1 and A2 from Tengqiao and Lizigou wild abortive rice in Hainan Island. Two maintaining lines of IR160 B1 and Zhenshan 97 B2 derived from different ecological areas, China and the Philippines. In the Six returen lines, three are subspecies Shan Indonica and three are middle type between Shan and Gen Jopanica also. Through plot experiment, plants investigation and statistics analysing, the results is that there are broad heredity with nine traits of grain yield. This just explains that those traits are true inherit-ance. And so, from the perspective of narrow heredity, the five traits, namely, the number of the highest plant, spikelet per panicle, seed set ratio, grain weight and plant height are higher. It means that there exists dominant epistatic gene. Of course, there is a reason to agree that this is a sub-system in rice genome expressing grain yield by profiles.
