ジャーナル フリー1) Hybrids among cultivated rice varieties are sometimes fertile and sometimes sterile according to the degree of afiinity between parental varieties. There is, however, no difference in the hybrid fertility between the reciprocal drosses, regardless whether the hybrid is fertile or poorly fertile. Such is the case with the crosses between an Indian variety, Surjamkhi, and two Japanese varieties, Sensho and Tsurumochi No. 1, as shown in Figures I and 2. 2) The situation with the crosses between cultivated and wild varieties is quite different. Seven cultivated varieties, including five Japanese and two Indian, were crossed reciprocally with two wild ones in ten combinations, the latter consisting of one Indian, O. sativa L. var. fatua L. and one Chinese variety, f. spontanea. All these crosses showed a remarkable difference in fertility between the hybrids from reciprocal matings. llybrids originated from the cross in which a wild variety partook as [the female parent showed, always a lower degree in both the seed-setting and pollen fertility than those from the reciprocal cross did (Figures 3 and 4).抄録全体を表示PDF形式でダウンロード (625K) -

ジャーナル フリー(1) In 1955 and 1956, we investigated the relationships between low t, emperature treatment period and autumn seed production in typical Chinese varieties. (2) The relationships between time of flower-bud differentiation and low temperature treatment period was recognized in middle and late stages, but was not noted in the early stage. The time of flower-bud differentiation varied in proportion to the length of the treatment period. Observation concerning the varietal difference of flower-bud differentiation showed that Kashin was early but Aichi was late, while Matsushima No. 2, Hakushoku-Hotoren and Mikawa were intermediate. (3) The plant which flowered in the warm season or before the 20 th of September, produced good pods, seed-setting, many seeds per pod, and high quality seeds. The quality of these seeds was not inferior to that of spring mattLring seeds, for all practical pur poses. However, extra early flowering plants did not show these good results.抄録全体を表示PDF形式でダウンロード (1633K) -

ジャーナル フリー1) To ascertain the sexual affinity of the new lines obtained from the japonica-indica intersubspecific hybrid of rice, 27 strains corresponding to Fll and F12 were crossed to their original parents. 2) 133 F1 plants from 17 strains crossed to japonica parent and 172 F1 plants from 23 strains to indica parent were grown, and the seed fertility of each F1 plant was determined for three strong panicles. The results were tabulated in table 1, as the values of max. min. and mean seed fertility with their variances and grain shape index. 3) Sexual affinitie, s of those newly tested lines were r6ughly grouped into two ; one group, having 26 lines, showed strong affinity to japonica type parent and weaker afiinity to indica type parent, in the former case the mean seed fertility of F1 was higher than 85%, but in the later case it remained below 45% The other group, represented by only one line, showed on the contrary weak affinity to japonica parent, that is 52% seed fertility, and strong affinity to indica parent namely 87% seed setting. Such relationship is clearly represented in fig. 1 and 2.抄録全体を表示PDF形式でダウンロード (609K) -

ジャーナル フリー1・水稲の収量に関与する量的形質を支配する遺伝子の作用と環境の影響との間の関係を究明せんとして，播種期を変えて栽培することによって遺伝子の作用，遺伝力，形質間相関が如何に変化するかを考究した。2.実験材料として出穂期に関してE3及びE乱遺伝子が関与している(赤藤外，1954)交配組合せ愛国×銀坊主のF7世代(1956)の出穂期に関する9遺伝子型(第1表)を用いた。これら遺伝子は稗長(赤藤外，1954)及び個体穂重(赤藤外，1957)にも関与する多面的発現の遺伝子である。抄録全体を表示PDF形式でダウンロード (798K) -

ジャーナル フリーThe authors decided the 3 genes affecting the growth habit of wheat in previous report. Among these 3 genes, E factor determines erect-type, both P and T factors control prostrate-type, but differ in their effect on prostrate as clarified in report l. In this paper, we clarified following points, changes in growth .habit, development of plant height, variation of heading dates in 4 experimental plots, control, long day, short day (10 hours) and glass house culture. Results obtained are briefiy summarized as follows : 1. Varieties having the E-gene affecting the erect-type are not aff6cted fcr growth habit, development of plant height and heading date by temperature and short day treatment. 2. Between the 2 genes (P, T), varieties containing the P factor affecting the prostratetype showed remarkable effects by temperature. So P factor seems to have intimate relation to thermo-reaction. 3. Change in growth habit, plant height and heading date, was increased by long day and decreased by short day in the varieties having the T gene controlling the prostratetype. So the gene T seems to have deeper relationship to photoperiodism. 4. Both P and T genes affecting the prostrate-type were observed having the intimate relationship to both thermo-effect and photoperiodism.抄録全体を表示PDF形式でダウンロード (1121K) -

ジャーナル フリーAccording to the results of Cucurbita-crosses the author has investigated, bud pollen grains; at 5 p. m. of the day before anthesis were found to have already high germination power. but to be unable to germinate and grow on styles, because they were contained in anther wall and wet. If only anther dehiscence had been hastened by some way, bud pollen grains would be able to germinate and grow on styles even at 5 p. m. of the day before anthesis. In this experiment the author attempted to make successful pollination in the evening with bud pollen grains from artificially dehisced anthers and futhermore to elucidate the relation between the preparation for ger'mination and anther dehiscence by artificial methods. In hastening anther debiscence, two lrLethods were found to be effective : the high temperature treatment of bud male flowers from two d.ays before anthesis and the placement of bud male flowers in the laboratory in summer after the longitudinal cutting of anther wall at noon of the day before anthesis.抄録全体を表示PDF形式でダウンロード (1265K) -
