Marker-assisted selection of diploid and tetraploid potatoes carrying Rpi-phu1, a major gene for resistance to Phytophthora infestans.
Article in Journal of applied genetics, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The Rpi-phu1 gene originates from an interspecific hybrid between Solanum stenotomum and S. phureja, and confers a high level of resistance to Phytophthora infestans (late blight) in potato. The Rpi-phu1 was introduced by crossing at the diploid level into the S. tuberosum gene pool and then transferred to the tetraploid level by means of 2n gametes. Tetraploid lines carrying the Rpi-phu1 were selected for further crosses. A molecular marker GP94, linked in mapping population 97-30 with the Rpi-phu1 (6.4 cM), was applied to other unselected populations (2 diploid and 1 tetraploid), and was shown to be useful in marker-assisted selection (MAS) of the resistant individuals. GP94 was applied also in commercial breeding in 2 tetraploid populations. Although the marker allele of GP94, characteristic for the Rpi-phu1 presence, was rare in the S. tuberosum gene pool, it seemed to be common in 2 other sources of resistance to late blight: S. ruiz-ceballosii and S. kurtzianum.
