Unequal chromosome division and inter-genomic translocation occurred in somatic cells of wheat-rye allopolyploid.

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
Newly synthesized wheat-rye allopolyploids were investigated by genomic in situ hybridization, over the first, second, third and fourth allopolyploid generations. Inter and intra chromosome connections were observed in 12 root-tip cells of CA4.4.7 (S(2) generation), and translocations between wheat and rye chromosomes were also detected in five root-tip cells. In root-tip cells of CA4.4.7.5 and CA4.4.7.2.2 (S(3) and S(4) generation), the chromosome connections occurred again, a dissociative small rye segment was detected in seven cells of CA4.4.7.5. In plants MSV6.1 and MSV6.5 (S(1) generation), almost half of the root-tip cells contained 13 rye chromosomes and the rest held 12 rye chromosomes, and all the cells of the two plants contained 42 wheat chromosomes. Five pairing configurations of rye chromosomes, including 5 II + 3 I, 6 II + 1 I, 6 II, 5 II + 2 I and 4 II + 4 I, were observed in pollen mother cells of the two plants. The two plants' progeny, including S(2), S(3), and S(4) generation plants, contained 42 wheat chromosomes and 12 rye chromosomes. Therefore, the inter chromosome translocation and unequal chromosome division could occur in somatic cells of wide hybrids. The unequal chromosome division in somatic cell could induce chromosome elimination at the early stages of allopolyploidization.
