In connection with our former studies (7), some anatomical observations were made on the formation of unfilled peanut fruits and the results obtained are summarized as follows: (1) In reclaimed land where is seen a high production of unfilled fruits, the occurrence of unfilling seeds was 75 0n 1954. Meanwhile, the remained ones identified as normal from their external appearance were proved, when examined anatomically, to contain abnormal seeds of 33-0x1.fcedp+0t showing cell shrinkage or collapse on surface of cotyledon, plumule or other organs and inducing brown colored spot or coloration when advanced. The abnormality of this type, though hidden at inner part of seeds, was ascertained, through microscopical examination, as same sign of unfilling to the previously reported nonpathological phenomena that existed on seed surface. And therefore it was revealed that the occurrence of unfilling is strikingly greater than the actual number counted by external appearance. (2) Usually the sign of unfilling does not develop isolately on the organs of seedcoat, cotyledon and plumule, but there is found an apparent tendency that it begins to appear earlier on plumule and cotyledon than on seedcoat, and furthermore initialiy at the inside of respective organ. It should be accordingly concluded that the sign of unfilling is induced from inner parts and gradually advances towa d the outer parts of seed.
