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 F 1 ’s because of abnormal flowers. Backcrossing the F 1 plant with C. pinnatifidum pollen resulted in mostly sterile BC 1 F 1 plants. Similarly, poor fertility was observed among the C. bijugum × C. judaicum F 2 . The annual C. cuneatum × perennial C. canariense F 1 ’s was partially fertile with intermediate morphology. Meiotic chromosome pairing in the annual × perennial F 1 ’s was mostly normal, but pollen fertility was approximately 50%. These plants flowered profusely but produced only a meagre yield of viable F 2 seeds and many shrivelled seeds. Similar to the situation in other interspecific crosses, the fertility and vigour of the F 2 plants derived from the annual × perennial cross were lower compared with that of the F 1 , 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.

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.
