Molecular and cytological analyses of 1BL/1RS wheat and fertility-restoring locations for male sterile lines with Aegilops cytoplasm.
Bibliographic record
Abstract
【Objective】 The present study aims to explore potentially superior sources of fertility-restoration and possible distribution for 1BL/1RS male sterile lines of Aegilops cytoplasm and to provide a guarantee for practical application of three lines system of strong vigor in wheat hybrid breeding and production via identifying 1BL/1RS translocation and categorizing restoring degrees of fertility among a vast number of wheat varieties(lines) randomly selected world-widely including different ecological areas in China and Canada.【Method】 Combining molecular and cytological techniques,the selected 256 wheat varieties(lines),as well as 8 male sterile lines,were tested for 1BL/1RS translocation,and the degrees of fertility-restoration were evaluated by Chinese domestic methods.【Result】 Approximately 20 % of the tested 256 wheat varieties(lines) were characterized with 1BL/1RS translocation,and the non-1BL/1RS wheat varieties(lines) were grouped into semi-sterility(about 86.15%),high-fertility(91.67%) and compete-fertility(100%);and the 1BL/1RS wheat varieties(lines) were mainly grouped into high-sterility and complete sterility accounting for 40%,respectively.The potential sources of fertility-restoration for male sterile lines were Chinese spring wheat region(60%) and South winter wheat areas including the middle and low Yangtze valley winter wheat region(65.85%),Southwestern winter wheat region(68.42%) and South of China winter wheat region(71.43%).【Conclusion】 The results indicate a potential basis of non-1BL/1RS wheat varieties(lines) for superior restoration of fertility for 1BL/1RS male sterile lines of Aegilops cytoplasm in Chinese spring wheat region and South winter wheat areas.

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.
