| (a) Distribution: The habitats of Ae. mutica were as follows.
I-VI are in the continuous area where we traveled by jeep. Accordingly, it can be said that Aegilops mutica occurs in the belt of 100-150 km wide from W 36o N 41o to 31o N 39.5o, which is the center of its distribution. Denizli (W 29o N 37.8o) is a little away, but this is considered to be nearly the southwestern limit of its distribution. The collection from Kemshly in the east-northern corner of Syria (U.A.R.), manifested that this species occur there in a common population mixed with Ae. speltoides, Ae. Aucheri and Triticum aegilopoides. Here is far away from the centre of its distribution in Turkey, but will be the south-eastern limit of its distribution. This fact will suggest that Ae. mutica would occur also in the neighboring south-eastern region (Guneydogu Anadolu Bolgesi) of Turkey. In each habitat in central Turkey, it was found that var. typica and var. loliacea and the intermediate type form a common population as shown in Tab. 3. (b) Variation: Variation was noticed with respect to the following characteristics.
(c) Flowering habit: The glumes open early in the morning and the anthers shed abundant pollen grains, as in the case of Secale, Ae. longissima and Ae. sharonensis. This habit will bring about the spontaneous cross-pollinations, which enrich the manifold combinations of variations in the wild population. It is, therefore, not appropriate to classify the varieties on the basis of such difference as caused by a Mendelian single gene, which flows freely from individual to individual by the natural cross in the wild population. (d) Seed fertility: All the original samples from Turkey. except the one from Denizli, showed high seed fertility. However, in Kyoto the progenies showed rather lower fertility. This is probably due to the unfavorable condition of Kyoto. Namely, the flowering time of Ae. mutica meets with the rainy season in Kyoto. A few original specimens from Turkey which showed lower fertility may presumably be due to the B-chromosome effects. (e) B-chromosomes: Regarding B-chromosomes Dr. Mochizuki (s. page 31) has studied rather extensively with the materials grown in Kyoto as given in the following table (Tab. 1). (f) Observations in Turkey: The data of the morphological analyses of the wild population of Aegilops mutica in Turkey (June 13, 1959) are given in Tabs. 2 and 3. |
