Toward the development of highly homozygous diploid potato lines using the self-compatibility controlling<i>Sli</i>gene
Bibliographic record
Abstract
Cultivated diploid potatoes (2n = 2x = 24) are self-incompatible, but can be altered to become self-compatible using the Sli gene. Previously, a diploid clone 97H32-6 was selfed up to S3 using the Sli gene. To explore the usefulness of the Sli gene for the production of highly homozygous diploid potatoes, 2 S4 families from the above 97H32-6 derived S3 lines (inbred series A) and 3 S5 families by continuous selfings from a different F1 (= S0) plant (inbred series B) were developed. The level of heterozygosity and the location of heterozygous loci on the genetic map were investigated using RFLP and AFLP markers. The average heterozygosity levels of the originally heterozygous loci decreased from 100% in S0 to 10.7% in S4 and 8.6% in S5 (inbred series A and B, respectively). The average rate of reduction in heterozygosity per generation (38.4% and 38.5% for inbred series A and B, respectively) was lower than the theoretically expected rate (50%). However, none of the loci or chromosome sections was exclusively heterozygous in the advanced self-progeny. Thus, highly homozygous and seed-propagated diploid potatoes could be obtained by repeated selfing using the Sli gene.

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.
