1 · What the graph read from it

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.

2 · The registry

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

key messageAlloplasmic male sterile breeding lines of Eruca sativa were developed by intergeneric hybridization with CMS- Brassica oleracea, followed by recurrent backcrosses and determination of the breeding value. ABSTRACT: Male sterile breeding lines of rocket salad (Eruca sativa) were developed by intergeneric hybridization with cytoplasmic male sterile (CMS) cauliflower (Brassica oleracea) followed by recurrent backcrosses. Five amphidiploid F1 plants (2n = 2x = 20, CE), achieved by manual crosses and embryo rescue, showed an intermediate habit. The plants were completely male sterile and lacked seed set after pollination with the Eruca parent. Allotetraploid F1-hybrid plants (4n = 4x = 40, CCEE) obtained after colchicine treatment were backcrossed six times with pollen of the Eruca parent to select alloplasmic diploid E. sativa lines. The hybrid status and the nucleo-cytoplasmic constellation were continuously controlled by RAPD and Southern analysis during subsequent backcrosses. The ploidy level was investigated by flow cytometry and chromosome analysis. Premeiotic (sporophytic) and postmeiotic (pollen abortive) defects during the anther development were observed in the alloplasmic E. sativus plants in comparison to the CMS-cauliflower donor. No further incompatibilities were noticed between the CMS-inducing cybrid cytoplasm and the E. sativa nuclear genome. The final alloplasmic E. sativa lines were diploid with 2n = 2x = 22 chromosomes and revealed complete male sterility and restored female fertility. Plant vigor and yield potential of the CMS-E. sativa BC5 lines were comparable to the parental E. sativus line. In conclusion, the employed cybrid-cytoplasm has been proven as a vital source of CMS for E. sativa. The developed lines are directly applicable for hybrid breeding of rocket salad.
