Studies on genetic variation in reed canary grass, Phalaris arundinacea L.: III. Seed yield and seed yield components
Bibliographic record
Abstract
Norwegian, Russian, and North-American populations of reed canarygrass, Phalaris arundinacea L., have been described in previous papers in this series as to the variation in alkaloid type and -concentration and forage yield and quality. The present paper presents the seed yielding aspects and gives a general view of the results. The local materials were generally late, though, as to their seed yielding capacity they were inferior only to the selected Canadian population Castor, which was superior in all characters. The two Russian populations showed genetic instability. Broad sense heritabilities over all clones were estimated to 0.77 and 0.84 for earliness in 1984 and 1985. respectively, and to 0.49,0.41 and 0.20 for number of panicles, seed yield, and estimated seed yield per panicle, respectively, in one year (1986). Concerning the total investigation, wide genotypic variations were obtained in all populations for most of the characters studied. Clear differences were revealed between the local adapted populations, still with wild type characters, and the selected populations. No significant relationships were found between the alkaloid concentration and the other characters studied, though the populations were different in this aspect. Synthetic varieties will be established from the present material.

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.
