| (g) Observations in Kyoto: The seeds obtained from the original
samples collected in Turkey were planted in the fall of 1959 and the segregation
with respect to pubescent vs. glabrous was observed in Kyoto in 1960 (Table
4). The patterns of segregation observed in Kyoto were as follows (Table 5). Seed fertilities of the original samples from Turkey and of the progenies in Kyoto are listed in the following table (Table 6). 3. Section Sitopsis of Aegilops from Egypt (U.A.R.), Jordan, Lebanon, Syria (U.A.R.) and Turkey In the section Sitopsis are involved Ae. speltoides, Aucheri, longissima, sharonensis and bicornis. 4 species of them were collected (Table 7). Ae. bicornis (2n=14, genome symbol SbSb) was collected along the highway from Alexandria - Matruh, Egypt (U.A.R.). Ae . longissima (2n=14, genome symbol S1S1) was collected from the skirt area of Mt. Hermon in Jordan, Syria (U.A.R.) and Lebanon. Ae. speltoides (2n=14, genome symbol SS) and Aucheri (2n=14, genome symbol SS) were found as either simple or mixed population in Aleppo-Antakya and Kemshly in Syria (U.A.R.) and Ankara-Amasya in Turkey. Intermediate type between speltoides and Aucheri was often found also. According to Eig (1929), the intermediate type is known as var. polyathera, but we wonder if it is appropriate to classify it as a variety. Dr. Tackholm, Department of Botany, Cairo University, Cairo, Egypt (U.A.R.), kindly suggested us to explore along the Mediterranean coast region of Sinai for the collection of Sitopsis, but the arrangement of the trip was not successful because of the military tension in there. 4. Einkorn from Syria (U.A.R.), Turkey and Greece Triticum aegilopoides, T. Thaoudar and T. monococcum: 2n=14, genome symbol-AA. In the suburbs of Ankara, wild Einkorn was found here and there. We selected a habitat 33.6 km W of Ankara for our detailed survey (s. the picture on the cover.). The data with respect to the awn length of the second floret were as follows (Table 8). Long vs. short of the awn of the second floret is the specific feature to identify T. aegilopoides (short) and T. Thaoudar (long), but these features were found mixed in a common population as seen from the table. The progeny test was carried out in Kyoto this year. The results were as follows (Table 9). Percival (1921) pointed out the occurrence of the intermediate type, and he included T. Thaoudar in T. aegilopoides, while Schieman (1932) established a collective species T. boeoticum instead. The variation in the color of glume and awn, viz. black, brown and white, was cominon. We also found plants having empty glumes with blackmargin on the ventral side of a spikelet. Early vs. late headding was also noticed. Some specimen had spiral culm which has been proved to be a heritable character. Individuals with various combinations of these characteristics occurred in a common population. Dr. Suzuka, one of the members of the mission, found a wild population of T. aegilopides in Vasilica, Greece. Most of the collected samples from there were immature and poor, but only one had a well grown long head. All the specimens from Greece were proved to be T. aegilopoides type practically with no awn on the second floret. Neither Thaoudar nor intermediate type was found there. |
