Analysis on Combining Ability of Major Quality Characters in Three-line Indica Hybrid Rice of South China
Bibliographic record
Abstract
Twelve widely utilized indica parents of north China,including 6 sterile lines and 6 restorer lines,were chose to analyze the combining ability of 12 quality characters by the way of NCⅡ mating design.The results showed that both general combining ability(GCA) and specific combining ability(SCA) of all the quality characters determined were significant at 5% or 1% level.It meant that all characters were both affected by the additive effects and non-additive effects,and the former were more important than the latter.The GCA and SCA effect were independent each other,which suggests that it is essential to make widely testcrosses in the selection of hybrid combinations.Based on the GCA effect and SCA variances of the parents,sterile lines Shuangqing A,Wanjin A,Bo A and Ⅱ-32 A and restorer lines Guanghui 998,gui 99 and HR 15 were recommendable at the major quality characters.

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.
