Yoshitaka IMAI, Benso KANNA1935 Volume 11 Issue 4 Pages 215-218

JOURNAL FREE ACCESS1. The occurrence of sterile flowers, as recessive mutation, was observed. The recessive segregates, which show a marked deficit in their segregating proportions, seem to be caused by the certation that takes place between normal and sterile microgametophytes.
2. Male-sterile-2 shows marked deficit in segregation, and so does male-sterile-3, although not so conspicuously.
3. Digenic segregation in the male-steriles shows conspicuous deficit, the recessive male-sterile ratio being low, even to the extent of appearing to be a monogenic.
4. The piebald seed character, which appeared by a new recessive mutation, is linked with the male-sterile-2, the recombination frequency being 9.1 percent.View full abstractDownload PDF (393K) -
CHROMOSOME PAIRING AND CHIASMA BEHAVIOUR IN THE MALE RUMEX ACETOSA WITH SPECIAL REFERENCE TO THE TRIPARTITE SEX-CHROMOSOMED. SATO, Y. SINOTO1935 Volume 11 Issue 4 Pages 219-226
Published: 1935
Released on J-STAGE: April 04, 2007
JOURNAL FREE ACCESSThe chromosome pairing and the chiasma behaviour were studied in the male Rumex Acetosa of the BB type. The triradial pairing of a tripartite sex-chromosome was ascertained and the crossing-over among tripartite chromosomes is predicted by the occurrence of chiasmata, based on the chiasma theory.View full abstractDownload PDF (669K) -
K. Tabuchi1935 Volume 11 Issue 4 Pages 227-233
Published: 1935

JOURNAL FREE ACCESSStudying the delicate character of the Japanese morning glory, the writer found two lines, the one being constant and the other inconstant. In the inconstant line, in which the delicate gene freqently changes to “normal, ” the mosaic individuals making vegetative mutation occur at 8.5 percent and the seminal mutants at 4.9 percent. A pedigree with 33.3 percent mosaics appaered sporadically. Two periclinals, normal-like leaf with split corolla and delicate-like leaf with entire corolla, arised as bud-variations, the former being due to the mutation from “delicate” to “normal” in the mesohistogen and the latter in the ectohistogen. The inconstant delicate acts as incomplete dominant to the constant form.View full abstractDownload PDF (1482K) -

Y. Ono1935 Volume 11 Issue 4 Pages 238-240
Published: 1935

JOURNAL FREE ACCESSThe numbers of chromosomes counted in twenty-two species, five varieties and ten agronomical varieties of Allium have been reported (Table 1) and of these, those of twelve species, three varieties and ten agronomical varieties (with asterisk in Table 1) are newly determined in the present work. As seen in the table, there are seven kinds of chromosomes in this genus, of which three (7, 8, 9) are a succesive series while the rest seem to be the respective multiples of these. The chromosome number of A. rubens is not yet precisely determined, though it is known to be over thirty-four. A. fistulosum var. viviparum shows a mixoploid tissue in the root-tip (Figs. 3, 4).View full abstractDownload PDF (244K) -
