Studies on Distribution of Fertility Genes for Male Sterile Lines with Aegilops Cytoplasm in Wheat
Bibliographic record
Abstract
In order to breed or selection restorer lines with high restoring ability to male sterile line in wheat effectively,8 male sterile lines in wheat with Ae.kotschyi,Ae.variabilis,Ae.ventricosa and Ae.bicornis cytoplasms were crossed to 310 wheat varieties from different regions,the restoring property of F1 had been tested and the distribution of fertility genes were studied as well by using clustering methods.The results showed:(1)The restoring gene from every wheat ecological region varies in proportion.The high-fertile varieties were beyond 50% in Chinese Spring Wheat Region and Southern Winter Wheat Region.And the varieties with maintenance ability were most in Canada and Northern Winter Wheat Region and were least in Spring Wheat Region.(2)The restoring abilities of different wheat varieties differed among regions.(3)Clustering results for the restoration ability of 48 wheat varieties showed that they were subdivided into 3 groups.In groupⅠ,all varieties were complete-sterile or high-sterile,and the average seed-set were less than 20%.In groupⅡ,most varieties were half-sterile,and the average seed-set varied from 20% to 55%.In groupⅢ,the varieties were high-fertile or complete-fertile and the average seed-set were more than 55%.(4)Clustering results for male sterile lines showed that K-type and V-type were included into the same group,while Ven-type and B-type into another group with 90-110 nucleus.V-type and B-type were clustered into the same group firstly,then K-type and Ven-type with 224 nucleus.Under the same cytoplasm,nucleus 90-110 and 224 were categorized into different groups.

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.
