Frequent Occurrence of Precocious Flowering in Zygotic Seedlings Derived from Crosses with a Monoembryonic and Male Sterile Acid Citrus Hybrid between Yuzu (C. junos Sieb. ex Tanaka) and Hanayu (C.hanaju Hort.exShirai)
Bibliographic record
Abstract
We successfully produced a male sterile and monoembryonic acid citrus hybrid plant that generated seedlings showing precocious flowering with high rates. Of 26 crosses wlth 16 acid citrus cultivars, three ('Sudachi'X'Yuzu', 'Hanayu' X 'Kabosu' and 'Hanayu' X 'Yuzu') were firstly found to generate precociously flowered seedlings with low rates. Second, 23 hybrid seedlings with 'Hanayu', 'Kabosu' and 'Sudachi' in their parents were crossed wlth 'Hanayu', 'Kabosu' and 'Yuzu', and then one cross (HY-16 X 'Yuzu') was found to generate precocious seedlings wlth a high rate of 60/0. When the hybrid plant HY-16 derived from 'Hanayu' X 'Yuzu' was crossed with 'Yuzu' in different years, it constantly generated seedlings showing precocious flowering with a rate of about 60/0, but it did not generate them when it was crossed with 'Hanayu'. When HY-16 was crossed with grapefruit cultivars, it generated seedlings exhibiting precocious flowering with very high rates of about 150/0. The seedlings derived from 'Hanayu' X'Yuzu' and selfing of 'Hanayu' and 'Yuzu' generated seedlings showing precocious flowering wlth low rates of about 10/0. HY-16 was a male sterile and monoembryonic plant with fruitful and seedy characters. The precociously flowered seedlings derived from crosses with HY-16 developed 6-33 Ieaves until flower bud formation that occurred between February to August on the shoot tip. Three-fifths of the seedlings for HY-16 X 'Yuzu' and one-second for HY-16Xgrapefruit were male sterile. These results suggested that HY-16 accumulated genes related to precocious nowering and that this hybrid was useful for rapid genetic analysis of various characters such as male sterility in Citrus.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
