Descendants
Relations are counted along the shortest line of descent. The rows in the diagram follow the order of crosses, so a variety with more than one path down can sit lower in the diagram than its relation here suggests.
It took on the "autumn-declining" fields
"Hokuriku No.36" was crossed in 1937 at the Ou Testing Site of the Ministry of Agriculture and Forestry Agricultural Experiment Station, taking "Ou No.199" as the mother and "Paddy Rice Norin No.1" as the father; the F3 seed was received in 1940, selection and fixing were pursued at this station thereafter, and from fiscal 1946 it was distributed to the relevant prefectures under the line name "Hokuriku No.36" while its regional suitability was examined.
Ishikawa Prefecture decided to adopt it as a recommended variety in fiscal 1950.
The cross was made in 1937; the father Norin No.1.
Its destination is written plainly.
The area expected for its spread in Ishikawa Prefecture, as the variety that should replace "Paddy Rice Norin No.1" on the flat land where "autumn decline" is severe, is estimated at roughly 6,000 cho.
"Autumn decline" is a soil condition in which the plant loses vigour late in the season and fills poorly. It replaces Norin No.1 on the fields where that is severe — about 6,000 cho.
Its own document and a later variety's document disagree about it
This document describes Kaganishiki this way:
Its blast resistance, in both leaf and panicle neck, is stronger than "Paddy Rice Norin No.1"'s, and the culm is strong.
Stronger than Norin No.1, with a strong culm.
But Tedoriwase's historical document, three years later, describes Kaganishiki inside Ishikawa's reason for adoption like this:
"Kaganishiki", adopted as a recommended variety in 1950, gradually increased its area and reached 20 cho by 1952, but while its blast resistance is slightly stronger than "Norin No.1"'s, its thin and somewhat long culm is not strong and it lodges easily; its fertiliser tolerance is weak, making it unsuited to fertile land and heavy fertilisation, and its grain quality is also somewhat inferior.
"Slightly stronger." "The culm is not strong and it lodges easily."
Its own document says strong, with a strong culm; the successor's document says slightly strong, and not strong. The same variety, written up differently by the same prefecture.
Neither says which is right. This site carries both as they stand. A breeding report is written to put a variety into the world. The next variety's report is written to replace it. When the purpose of the writing differs, so does the assessment of the same thing.
Note also "reached 20 cho by 1952". The area expected at adoption was 6,000 cho. The actual area is one three-hundredth of the forecast.

How the seed parent of Norin No.1 is written
- Moritawase, written 森多早生 — イネ品種データベース検索システム 交配系譜図「北陸4号」
- Moritawase, written 森田早稲 — イネ品種データベース検索システム「北陸4号(水稲農林1号)」品種来歴文書
The two spellings appear in the same NARO database, in the pedigree field and in the historical document respectively. We use the pedigree field's spelling and list the other.
How Kamenoo No.4 is written
- 亀の尾4号 — イネ品種データベース検索システム 交配系譜図「陸羽132号」
- 亀ノ尾4号 (the common spelling)
We follow the NARO database. The commonly seen spelling uses a katakana no; we prefer the spelling we can cite.
On naming
Variety names are proper nouns. We use a name in this language only where a published source for it can be cited; otherwise the Japanese name stands.
What we have not yet confirmed
We have not looked below the top twenty
The site covers the twenty most widely planted varieties of the 2024 crop and the varieties that connect them back to Koshihikari. Many descendants exist below that line; we have not yet verified them against primary sources.
The year Masshigura was crossed
Neither Aomori Prefecture's table of recommended-variety characteristics nor the NARO database gives the year Masshigura (Aokei No.138) was crossed. The cross itself, Ou No.341 / Yamagata No.40, and its adoption as a recommended variety in fiscal 2004 are confirmed from primary sources; the year of the cross is not. For the same reason we do not say which parent was the seed parent. On 8 October 2026 we went back to the breeder's own side. The Masshigura page in the variety database of the Aomori Prefectural Industrial Technology Research Center's Agriculture and Forestry Research Institute carries a heading reading “The origin of Masshigura” — with nothing under it. Of the institute's bulletins, only No.42 (2015) onward are online, and the issue that would hold the breeding report for Masshigura is not among them. So the year of the cross is absent from the breeder's own published material as well.
