Norin No.19

Both parents are Hokkaido landraces

"Paddy Rice Norin No.19" was crossed in 1929 in the Ministry-designated paddy rice breeding trial at the Kamikawa Branch of the Hokkaido Agricultural Experiment Station, taking "Hashiribozu" as the mother and "Nibushi" as the father

The mother is Hashiribozu, the father Nibushi — both Hokkaido landraces, with neither a Norin number nor a regional one.

Follow this site's pedigrees back and almost everything arrives at Honshu lines: Rikuu No.132, Aikoku, Asahi, Ginbozu. Norin No.19 comes from another root.

That Norin No.19 became the father of Paddy Rice Norin No.42, whose mother was Paddy Rice Norin No.1.

Hashiribozu × Nibushi → Norin No.19 (Hokkai No.79)
                   │
Norin No.1 × Norin No.19 → Norin No.42 (Hokkai No.103)

The Honshu line and the Hokkaido line join at Norin No.42. Seen from Koshihikari, Norin No.42 is a half sibling — and that half sibling's father's side alone runs off into a different pedigree.

The provisional name was "411"

From April 1934 under the provisional name "411", and from April 1936 under the line name "Hokkai No.79", its seed was distributed within Hokkaido, chiefly to the northern districts with a short rice-growing season, to confirm regional suitability; in April 1941 it was given the variety name "Paddy Rice Norin No.19".

The name changed in three stages.

Paddy Rice Norin No.42's provisional name was "1735". At the same Kamikawa Branch, provisional names were nothing but numbers.

Crossed in 1929, named in 1941. Twelve years.

The preface's count matches Norin No.20's

And the fine new varieties bred by this system already reach 38. March 1943, Agricultural Policy Bureau, Ministry of Agriculture and Forestry

Paddy Rice Norin No.20's preface also says "already 38", in the same March 1943.

Two documents of the same year carry the same number. The count belongs to the year the report was issued, not to the variety — something only two documents side by side could confirm.

Stronger in the years the weather breaks

Its grain is medium, and compared with "Hashiribozu No.2" it is about equal or a little higher-yielding when the weather is settled, while the trial plantings show it higher-yielding when the weather is unsettled. This tendency is conspicuous on clay-soil paddies rather than sandy ones.

Level in settled years, higher-yielding in broken ones.

Chiyohikari was the reverse: "superior when the year's yields are generally high and inferior when they are not" — a variety that rises when conditions do.

Norin No.19 is a variety that shows its difference in the bad years. And the document goes on to say the difference depends on the soil.

Its suitable ground is judged to be the cold-damage districts — the Kitami district of northern Hokkaido, and the Soya districts north of Wassamu — where blast damage is locally light but the risk of cold-weather damage is great.

A variety aimed at cold-damage country. "The Soya 船 districts" appears to be a transcription that has broken down, but since there is no telling how, it is quoted as it stands.
