Introgression of teosinte branched1 gene from wild-progenitor enhances prolificacy in subtropically-adapted maize.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
MAIN
conclusionIntrogression of the tb1-T allele from teosinte into subtropically adapted maize inbreds led to an ~3-fold enhancement in prolificacy in reconstituted hybrids, underscoring its significant utility in baby corn breeding. Traditional maize generally possesses one ear per plant in contrast to >100 ears found in its wild relative - teosinte. The teosinte branched1 (tb1) gene has been identified as the master regulator for prolificacy (>1 ears per plant) in maize. So far, tb1 gene has not been introgressed into subtropical maize germplasm for enhancement of prolificacy using marker-assisted backcross breeding (MABB). Here, tb1-T allele present in teosinte (Zea mays ssp. parviglumis) has been introgressed into seven elite parental inbreds using molecular breeding. Seven inbreds with tb1-M allele were parents of nine popular maize hybrids. We developed an InDel functional marker (MGU-tb1-Hopscotch) that successfully differentiated the tb1-T (722 bp) allele from tb1-M (559 bp) allele, and used in BC
