The judgement which is subject of research has denied legal rescission of division of the inherited property by agreement based on (1) the fact that the division of inherited property terminated at the time of concluding mutual agreement in its nature while only the relationship of claim and obligation between the inheritor who has paid for such obligation and the inheritor who has acquired such obligation in the mutual agreement remains (2) and the fact that the legal stability is considerably hindered as the re-partition of inherited property having retroactive effect becomes unavoidable in case of approving the legal rescission of the division of the inherited property by agreement. But it is reasonable to also approve legal rescission on the division of the inherited property by agreement in case the division by agreement actually has the nature such as conditional donation between joint heirs (1) from the fact that the division of the inherited property by agreement gets the nature of disposal equivalent to exchange, transfer and abandonment of share between joint heirs in actuality, (2) and the fact that there are no other theories in approving the validity of mutually agreed rescission despite the fact that the re-partition of inherited property having retroactive effect is unavoidable even in case of the mutually agreed rescission of the division by agreement among all joint heirs. However, as the division of the inherited property by agreement is a contract that gets concluded only if all joint heirs participate, even the legal rescission for the reason of not fulfilling the obligations paid by one party of the heirs during the division by agreement must be considered as possible only by expression of intentions from all other joint heirs excluding this one party.

Due to the lack in storage facility, considerable amount of rice is stocked in the open air, which causes increased stale flavor and deteriorates palatability and merchantable quality. Lipoxygenase-3(LOX-3) is involved in the production of volatile constituents in stored rice, and the development of stale flavor is delayed in LOX-3 null rice. LOX activity in the rice grain is localized in bran fraction and the tropical Japonica cultivar 'Dawdam' was reported that the absence of LOX-3 is inherited as a simple recessive trait. Also, it was reported that the peroxidation of unsaturated fatty acids occurs at lower levels in the 'Dawdam' bran fraction during storage than in rice varieties with LOX-3. This study was conducted to develop LOX-3 null rice lines using 'Dawdam' and investigate changes of physicochemical properties of the lines stored at different storage temperatures and periods. So we analyzed texture, toyo glossiness value, germination rate and lipoxygenase activity of 15 LOX-3 null rice lines on the condition of which rough rice had been stored at different temperatures (high temperature condition at $35^{\circ}C$ and low temperature condition at $15^{\circ}C$ for 4months. Hardness and stickiness of the lines tendered to be increased when it was stored at high temperature and adhesiveness, springiness, cohesiveness and chewiness was not considerably different according to storage temperatures and periods. The germination rate of HR29062-B-98-2-1-B among LOX-3 null rice lines was higher than another lines, 99.3, 94.0% after 4months stored at low temperature and high temperature, respectively. The lipoxygenase activity was 3,304, 1,601unit/mg protein after 4months stored at low temperature and high temperatures, respectively. So, it is thought that this line will be useful to breed rice varieties with high storability after tested on agricultural traits.
