Novel haplotype combinations reveal enhanced seedling vigor traits in rice that can accurately predict dry biomass accumulation in seedlings.

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
Seedling vigor is of vital importance for the initial plant establishment of direct-seeded rice. Here, 166 recombinant inbred lines were employed to assess eight seedling vigor traits over the first 25 days of germination. Significant correlations were found between most traits, and statistical analysis has revealed, for the first time, a linear relationship that uses seedling height and fresh weight to accurately predict the accumulation of dry biomass. Further, a subset of 20 lines, spanning the phenotypic range of the larger population, were genotyped by using 16 simple sequence repeats (SSR) markers known to be associated with seedling vigor traits. Markers RM317 and RM348 linked with significantly different phenotypes, including seedling height and fresh weight. One combination, haplotype II-1 (RM317 (I/II) and RM348 (1/2)), consistently produced superior values for seedling height, root length, and leaf length. The new prediction tool for seedling dry weight, namely the haplotype of RM317 and RM348, will have a wide range of applications in breeding strategies by using marker-assisted selection to produce elite lines that optimize genetic composition contributing to seedling vigor.
