Studi Keragaman Galur F4 Hasil Persilangan Padi Varietas IPB 4S dengan Situ Patenggang
Bibliographic record
Abstract
Penelitian ini bertujuan untuk mendapatkan informasi keragaman galur-galur F4 hasil persilangan padi IPB 4S dan Situ Patenggang dan membandingkannya dengan varietas pembanding. Penelitian ini dilaksanakan di Kebun Percobaan Cikabayan, Institut Pertanian Bogor. Penanaman dilakukan dengan menanam populasi F4 hasil persilangan IPB 4S dengan Situ Patenggang sebanyak 100 galur terpilih dengan 4 varietas pembanding yaitu IPB 4S, Situ Patenggang, 7R dan 6R. Peubah yang diamati yaitu tinggi tanaman, jumlah anakan total, jumlah anakan produktif, panjang malai, jumlah gabah bernas, bobot gabah bernas, bobot gabah hampa, dan bobot 100 butir. Hasil perhitungan nilai tengah menunjukkan beberapa karakter populasi F4 memiliki nilai tengah lebih baik dari pembandingnya. Nilai heritabilitas dan koefisien keragaman genetik yang tinggi terdapat hampir pada seluruh karakter. Seleksi dilakukan berdasarkan bobot gabah bernas per tanaman karena memiliki nilai heritabilitas arti luas dan koefisien keragaman genetik yang tinggi.
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.
How this classification was reachedexpand
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.
