Interspecific hybridization in wild <i>Cicer</i> sp.
Bibliographic record
Abstract
With 2 figures and 5 tables Abstract Interspecific hybridization between closely related wild Cicer species was performed. The Cicer judaicum × C. pinnatifidum cross resulted in sterile F1’s because of abnormal flowers. Backcrossing the F1 plant with C. pinnatifidum pollen resulted in mostly sterile BC1F1 plants. Similarly, poor fertility was observed among the C. bijugum×C. judaicum F2. The annual C. cuneatum × perennial C. canariense F1’s was partially fertile with intermediate morphology. Meiotic chromosome pairing in the annual × perennial F1’s was mostly normal, but pollen fertility was approximately 50%. These plants flowered profusely but produced only a meagre yield of viable F2 seeds and many shrivelled seeds. Similar to the situation in other interspecific crosses, the fertility and vigour of the F2 plants derived from the annual × perennial cross were lower compared with that of the F1, yet another demonstration of the complex crossing barriers prevalent in the genus Cicer. The implications of the above findings to chickpea breeding are discussed with emphasis on the actual value of distantly related wild relatives for chickpea improvement.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
