Plant genome design method defines DNA markers M1 to M5, for each target region, DNA marker M2 is at an upstream side of a target region, or upstream thereof, DNA marker M1 is upstream of DNA marker M2, DNA marker M4 is at a downstream side of the target region, or downstream thereof, DNA marker M5 is downstream of DNA marker M4, and DNA marker M3 is in the target region; and designs a genome so that a substitution region, containing the target region, in a chromosome of the original cultivar to be substituted with a chromosome fragment derived from the foreign cultivar has an end on an upstream side between DNA marker M1 and DNA marker M2, and an end on a downstream side of the substitution region between DNA marker M4 and DNA marker M5.

Method of plant genome design, method of creating new cultivar and new cultivar

Plant genome design method defines DNA markers M1 to M5, for target region, DNA marker M2 is defined at an end on an upstream side of a target region, or upstream thereof, DNA marker M1 is defined upstream of the DNA marker M2, DNA marker M4 is defined at an end on a downstream side of the target region, or downstream thereof, DNA marker M5 is defined downstream of the DNA marker M4, and DNA marker M3 is defined in the target region; and designs a genome so that a substitution region, containing the target region, in a chromosome of the original cultivar to be substituted with a chromosome fragment derived from the foreign cultivar has an end on an upstream side between DNA marker M1 and DNA marker M2, and an end on a downstream side of the substitution region between DNA marker M4 and DNA marker M5.

An object of the present invention is to provide a new rice cultivar that matures earlier than the original cultivar, and a method for causing a rice individual to mature earlier. The present invention relates to a rice cultivar Koshihikari kazusa no. 6 having the cultivar registration application number 25587, a progeny individual obtained by crossbreeding two individuals selected from the group consisting of an individual of the aforementioned cultivar and a progeny individual thereof, and a method for causing a rice individual to mature earlier that comprises replacing a region corresponding to a region containing base number 31,720,064 to base number 31,724,043 of the third chromosome of rice cultivar Nipponbare with a chromosome fragment composed of the corresponding region of rice cultivar Koshihikari kazusa no. 6 or rice cultivar Habataki in the third chromosome of the rice individual.

Cultivar, method for differentiating plant cultivars, and method for causing earlier maturing of rice individual

An object of the present invention is to provide a new rice cultivar that matures earlier than the original cultivar, and a method for causing a rice individual to mature earlier. The present invention relates to a rice cultivar Koshihikari kazusa no. 5 having the cultivar registration application number 25586, a progeny individual obtained by crossbreeding two individuals selected from the group consisting of an individual of the aforementioned cultivar and a progeny individual thereof, and a method for causing a rice individual to mature earlier that comprises replacing a region corresponding to a region containing base number 31,720,064 to base number 31,724,043 of the third chromosome of rice cultivar Nipponbare with a chromosome fragment composed of the corresponding region of rice cultivar Koshihikari kazusa no. 5 or rice cultivar Habataki in the third chromosome of the rice individual.

A plant information management system comprising: a seed identification information input device; an individual plant identification information retrieval device; an individual plant identification information input device; a new seed identification information retrieval device; a storage location information retrieval device; a project database management device; a seed database management device; a project database memory device; and a seed database memory device.

Plant information management system and plant information management method

A gene that regulates the increase and decrease of the particle-bearing number (including glumous flowers, fruits, and seeds) of plants was successfully isolated and identified by a linkage analysis. In addition, breeding methods that utilize this gene to increase the particle-bearing number (including glumous flowers, fruits, and seeds) of plants were also discovered. The present invention is useful in fields such as breeding of improved plant varieties.
