Study on the Genetic Variations of Main Traits Among Superior Tree Progenies of Jatropha curcas L. at Seedling Stage
Bibliographic record
Abstract
In order to improve the breeding level and provide excellent materials of Jatropha curcas for constructing seed orchard and scion-plucking nursery.Randomized complete-block designs were used to the superior tree progeny test of main wild or semi-wild plants of Jatropha curcas in Qiaoma forest farm and Luodian state-owned forest.The results showed that there were not significant differences in seedling height and seedling base diameter among the 8 provenances,e.g.,Ceheng(Guizhou),Lurong(zhengfeng,Guizhou),Lugong(zhengfeng,Guizhou),Leyuan(Wangmo,Guizhou),Lekang(Wangmo,Guizhou),Luodian(Guizhou),Longlin(Guangxi),Tianlin(Guangxi),and there were also not significant differences among different families within the same provenance.In Qiaoma experiment site,seedling height of and seedling base diameter 80 superior tree progenies had significant differences had great significant differences.In Luodian experiment site,24 superior tree progenies had great significant differences in both seedings height and base diameter.In both experiment sites,the degree of variation of seedling height was higher than that of base diameter.The CVs,i.e.coefficient of variations,that of the seedling height and seedling base diameter in Qiaoma were 42.79% and 17.75% respectively.and that in Luodian were 18.95% and 8.88% respectively.Both seedling height and seedling base diameter had higher family heritability in Luodian experiment site,and the family heritability of seedling base diameter was higher than that of seedling height.The family heritability of seedling height in these two experiment sites was 0.29,0.68 respectively,and that in ground diameter were 0.41 and 0.68,respectively.The different performances of seedling height and base diameter of superior tree progenies were mainly controlled by both heredity and environment,but the variation degree of the ground diameter was highly controlled by heredity.It is concluded that the breeding of Jatrohpa curcas should be started with the superior tree selection,whereas it is not appropriate to start with the selection of the seedling height and ground diameter performance by the provenance trial at seedling stage.

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.
