Combining Ability Estimates for Yield and Fibre Quality Traits in Line X Tester Crosses of Upland Cotton, (Gossypium hirsutum)
Bibliographic record
Abstract
This study was to estimate the GCA of the parents and SCA considered for the development of high yielding and betterquality cultivars. Eleven genotypes and 28 F1 hybrids obtained by crossing 4 lines and 7 testers in line X tester matingsystem were sown in randomized complete block design. L X T analysis revealed significant GCA and SCA effects forall the traits except earliness. Among the parents: MCU 12 for number of bolls per plant, boll weight, seed cotton yieldper plant, F 1861 for seed cotton yield and number of bolls per plant, SOCC 17 for earliness, SURABHI for number ofsympodia and TCH 1641 for ginning outturn and lint index with high GCA. Parent F 776 and F1861 were goodcombiners for fibre quality traits. The high yielding quality hybrids were deducted with significant SCA effects for seedcotton yield and fibre characteristics.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
