Abstract
本研究采用ISSR标记技术,从公开发表的文献中选取多态性丰富,稳定性好,重复性高的12条IS-SR引物对马铃薯品种‘转心乌’及其100个实生个体的遗传变异性进行研究。研究结果表明,12条引物共检测到77条带,其中每条引物检测到5～7条带,平均每个位点的等位基因变异数为6.4条;多态性条带数为43条,多态性比例为55.84%。供试材料间的遗传相似系数的变异范围介于0.78～0.96之间,在0.785处可将所有供试材料划分为3大类。UPGMA聚类分析结果表明,100个材料与母株相比,虽然遗传相似性很高,亲缘关系较近,但均有不同程度的变异,没有1个材料与母株在基因型上表现完全相同;实生群体内在分子水平上也没有检测到完全一致的两个个体,这表明要利用实生群体获得完全一致的群体有相当的难度。该结果也表明利用实生种子保存种质,不失为保存马铃薯遗传多样性的有效方法。

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; both teacher heads agree on what is shown here.
