The Restoring and Maintaining Characteristic among K-type and F-type Wheat Male Sterile Lines
Bibliographic record
Abstract
In order to study the pollen abortive characteristics of male sterile lines of K-type and F-type wheat and to screen their strong restorers lines and maintainers, the I 2 -KI staining method was used to observe the pollens types of sterile lines in flowering period, and 583 quality wheat varieties (lines) were hybridized with sterile lines to investigate the self-seed set ratio on F 1 of combinations. The results show that:(1)the pollen sterility rate of K-type and F-type male sterile lines were as high as 96.97% and 97.73%, respectively. The main types of pollen abortion were stained aborted tape and typical aborted tape. (2) the self-seed set ratio of K-type and F-type sterile lines (domestic) were 4.61% and 1.98%, respectively. (3) 34 self-seed set ratio of F 1 (international) were more than 100% and 11 below 20%. (4) ‘Liangxing805’, AQ001, ‘Lin7287’, ‘Jimai22’ were excellent restorer lines to K-type sterile line. ‘Bao8696’, ‘Nongda3291’, ‘Ke1201’, ‘Ji8906069’ could be used as good maintainers for K-type sterile line. ‘Bao8696’, ‘15Zhan24’, ‘Luomai23’, ‘Linyuan801’ were excellent restorer lines to F-type sterile line. ‘15Zhan11’, ‘Wenhang6’, ‘Linyu5’, ‘Fengyou8’ could be used as good maintainers for F-type sterile line. The results showed that both K-type and F-type sterile lines were completely aborted and stable, and they were easy to find good maintainer lines and restorer lines, and the latter had stronger recovery capability.

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.
