Kinki No.35 is the later Norin No.23

At the Konosu Testing Site of the Ministry of Agriculture and Forestry Agricultural Experiment Station, an artificial cross was made in 1943 taking "Kinki No.35", later Norin No.23, as the mother and "Norin No.1" as the father

"Kinki No.35", later Norin No.23. One sentence ties the line name to the Norin number.

At the time of the cross it was Kinki No.35; by the time the document was written it had become Norin No.23. Koshihikari's mother was likewise Kinki No.34 at the cross and Norin No.22 afterwards. This is why building a pedigree from variety names alone trips you up.

The father is Norin No.1. The cross was made in 1943, the year before Koshihikari's.

A prefecture counting off Norin No.1's weaknesses

Giving Ishikawa's reason for wanting it, the document sets out where Norin No.1 stopped.

"Norin No.1", which occupies % of Ishikawa's paddy area, has a great many excellent traits, but its blast resistance is somewhat weak and it lodges somewhat easily, so growing it in districts where blast is endemic is extremely difficult.

The share of planted area is left as a blank. Whether it was never written or was lost, we cannot tell.

The document then records that the earlier replacement had not been enough either.

"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.

Put in one replacement and another defect appears. So the next one is needed. That repetition is what the pedigree diagram actually records.

The document gets its own name wrong

The conclusion of the Ishikawa section opens like this:

However "Etsunan No.5" is a slightly short-culmed, panicle-number-type early non-glutinous variety ripening about when "Norin No.1" does

This is the document for Etsunan No.6, and it says Etsunan No.5. The surrounding description matches Etsunan No.6.

The document does not say which is the error, so it is left uncorrected and noted. The historical document for Hatsunishiki carries the same kind of discrepancy.

It became Chidori's mother

Ten years later Tedoriwase became the mother of Chidori. The partner was Norin No.22 — Koshihikari's mother.

Norin No.22 crossed onto Tedoriwase, a child of Norin No.1. The same two varieties that made Koshihikari meet again, one generation out of step.
