Genome analysis and introgression of multiple disease resistance into pre-breeding lines derived from greengram × ricebean crosses.
Article in Molecular biology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundGreengram (Vigna radiata) productivity is constrained by major pests and diseases, and introgression of ricebean (Vigna umbellata) derived genomic segments conferring disease resistance through interspecific hybridization offers an effective strategy to broaden the genetic base and enhance resistance to biotic stresses. METHODS AND
resultsIn the present study, three advanced pre-breeding lines (COGRISC 1, COGRISC 2 and COGRISC 3) developed through interspecific crosses between greengram (CO 6 and CO 7) and ricebean (RBL 35 and LRB 576), were evaluated. These lines exhibited ricebean-like qualitative traits, including hypogeal germination and purple hypocotyl colour, while biometrical traits showed intermediate expression between the parents. The pre-breeding lines exhibited partial fertility, ranged from 37.50 to 78.50%. To confirm ricebean genome introgression, 155 adzuki bean-derived SSR markers were screened for parental polymorphism, of which 124 (80%) were polymorphic and used for genotyping. Ricebean-specific marker alleles predominated in the pre-breeding lines, with 71 (57.30%) markers detected in COGRISC 1 and COGRISC 2 and 65 (52.40%) markers in COGRISC 3. Graphical genotype analysis revealed a mosaic pattern of introgression across all linkage groups with predominance of ricebean genomic segments. Cluster analysis grouped ricebean parents and pre-breeding lines together. All lines exhibited disease-free reactions against Mungbean Yellow Mosaic Virus (MYMV), powdery mildew, and leaf crinkle disease under artificial screening, and to cercospora leaf spot under field conditions.
conclusionsThe results demonstrate that ricebean-derived genomic segments confer multiple disease resistance, highlighting the potential of these lines as donor material for greengram improvement.
