Quality Difference of Near-Isogenic Lines with HMW Glutenin Subunits 7+8~* and 17+18 in Wheat Cultivars Longmai 20
Bibliographic record
Abstract
【Objective】 Determining the genetic differences between high molecular weigh glutenin subunits (HMW-GS) 17+18 and 7+8*.【Method】 HMW-GS 7+8* was introduced into Longmai 20 (1,17+18, 5+10) by 5 consecutive backcrosses with biochemical marker assisted selection from a Canadian extra strong wheat cultivar Glenlea possessing an over expression of the Bx7 subunit. The near isogenic lines (NILs) of HMW-GS 17+18 and 7+8* were obtained and grown in the experimental field of Crop Breeding Institute of Heilongjiang Academy of Agricultural Sciences, Harbin in 2005. The experimental design was a randomized block with six replicates. 【Result】In comparison to NILs with 17+18 subunit, the average of quality parameters of NILs with 7+8* subunit were 5% (P=0.012), 4% (P =0.018), 10% (P=0.013), 13% (P=0.258), 256% (P=0.029) and 86% (P =0.020) higher in flour protein content, dry gluten content, Zeleny sedimentation, development time, stability and breakdown time, respectively, and were 2% (P =0.043) and 35% (P=0.007) lower in the ratios of wet gluten content to dry gluten content (wet gluten/dry gluten ) and degree of softening, respectively. 【Conclusion】The subunits 7+8* have a strong positive effect on dough strength.

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.
