| 内容記述 | Cytological and morphological properties of autotetraploid buckwheat obtained through colchicine treatment were observed. The results may be summarized as follows ; 1. In 1976, treatment with colchicine to seed were applied to a local variety (KATAOKA) of buckwheat, Fagopyrum esculentum M. The authors have succeeded in obtaining about 40 per cent of autotetraploid plants. 2. In the second generaiton (C₂) after treatments, tetraploid showed more vigorous in growth or large size in some morphological characteristics as compared with diploids. The size of guard cell of stoma and pollen grain were about one and a half times and twenty per cent greater, respectively. 3. About 90 per cent of chromosome paired as bivalents in the first metaphase of tetraploid buckwheats, and consequently univalents, trivalents and quadrivalents chromosome pairings were observed rarely. This fact seems to be important with regard to the ability of seed set or grain yield. 4. Seed set of tetraploid was decreased only a few per cent as compared with diploid. But, the seeds from tetraploid plants were greater than those from diploids, about 15 to 20 per cent in size and 40 per cent in weight increased than those in diploids. From the results described above, we may suppose that the present autotetraploid of buckwheat were useful for breeding materials. | |||||||||||
