The rice plant according to the present invention is a rice plant obtained by crossing the rice plant varieties 'Koshihikari' with 'Kasalath' and having improvement in both lodging resistance and decorticated grain size, wherein said rice plant has on the chromosome any one of base sequences selected from the groups consisting of: (i) a base sequence of SEQ ID NO: 1, (ii) a base sequence having at least 80% identity with the base sequence of (i) above, and (iii) the base sequence of (i) above, in which one or several bases have been deleted, substituted, inserted or added, and wherein the remaining region of the chromosome is composed of chromosomes derived from Koshihikari. According to the present invention is to provide a new rice plant which maintains the good eating quality as a characteristic of Koshihikari and has excellent lodging resistance and large grains is provided.

Rice plant and method for producing the same

A gene relating to the regeneration ability of plants was successfully isolated and identified using linkage analysis. Furthermore, methods for breeding highly regenerative varieties, methods for transforming unculturable varieties, and methods for selecting transformed cells, wherein these methods utilize this gene, were also discovered. The present invention is useful in fields such as cultivar improvement and gene analysis that uses transformation methods.

Genes that confer regeneration ability to plants, and uses thereof

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.
