抄録

Investigations on the heredity of characters in the turnip hybrids between the following pairs were carried out;<br> Yonagokabu×lyohikabu, <br> Iyohikabu×Yonagokabu, <br> Yajimakabu×Hikonekabu, <br> Tennojikabu×Yajimakabu, <br> Hinokabu×Tennojikabu, <br> Yurugikabu×Tennojikabu, <br> Hikonekabu×Tennojikabu, <br> Sapporomurasakikabu×Shogoinkabu, <br> Sapporomurasakikabu×Hakatakabu, <br> Shogoinkabu×Omikabu, <br> Shogoinkabu×Hakatakabu, <br> Hakatakabu×Kokabu, <br> Oyabukabu×Hakatakabu, <br> Kokabu×Sapporomurasakikabu<br> The results may be summarized as follows.<br> 1. European type×Japanese type Generally in the hybrids that comes from this crossing, European type appears viz. pubescent leaves dominate glabrous leaves, and in plant form the divergent character dominates the upright character.<br> 2. Leaf shape<br> In the hybrid between the type with deeply dissected leaves and the type with entire (or sha-llow dissected) leaves, the intermediate form app-ears.<br> 3. Root shape<br> Generally in regard to root shape, the hybrid shows the intermediate form between parents.<br> 4. Colouring and pigment in the root<br> a. In colour of root above the ground green is dominant over white.<br> b. Both in leaves and in root, purple colouring is completely dominant over red colouring. And from the chemical point of view, it may be said that cyanin type shows complete dominance over pelargonin type.<br> c. In the hybrid between the red coloured root type and the white ones, pink coloured root type has not shown up, but purple ones has appeared. And our chemical survey identified the pigment of the hybrid with cyanin.<br> 5. Texture of root, rate of root growth and bolting<br> In any case the intermediate form (between pdrents) appears.<br> 6. Epidermal types of seed<br> In the hybrid between A type and B type, A type dominates B type. (The anatomical observation of the transverse section of seeds shows that A type is characterized by distinct feature of cells, swelling when they absorb water. On the contrary, in B type, epidermal layer seems only membranous, possessing indistinct feature.)
