サトイモは古くから食用として賞味され、現在でも世界
的に重要な澱粉作物である。特に「八つ頭」などの品種
は最も良食味品種として知られている。Taro has been enjoyed as food since ancient times, and is still an important starch crop worldwide. In particular, varieties such as ``Yatsuzu'' are known as the best-tasting varieties.
しかしながら、これらの品種は球根の形状が調理に不便
であるため商品性が低く、一般に調理用として用い難い
点があった。However, these varieties have low marketability because the shape of the bulbs is inconvenient for cooking, and are generally difficult to use for cooking.
そこで、調理し易い形状のサトイモ、特に「八つ頭」等

照射することが行われたが、成功するに至っていない。Therefore, attempts have been made to utilize naturally occurring mutations in taro varieties that are easy to cook, especially varieties such as ``Yatsuzu'', and to breed the mutants. In order to increase the height, radiation (gamma rays) has been irradiated, but this has not been successful.

に除皮し易いサトイモを得ることができる。The present invention involves removing the top of a taro stalk, treating it with a mutagenic substance to induce mutations, and then
These are a method for creating artificial taro mutants by isolating and growing mutants through sterile culture, and a method for breeding new taro plants using the taro mutants created by this method as materials. This makes it possible to obtain taro that is easy to remove the skin during cooking.
本発明の適用対象とするサトイモは、主として八つ頭群
、ニゲイモ群に属するサトイモである。The taro to which the present invention is applied is mainly a taro belonging to the Yatozu group and the Nageimo group.
八つ頭群はサトイモ品種の中で最も良食味品種として知
られ、古くから作られている品種である。Yatsuzu-gun is known as the best-tasting taro variety and has been produced for a long time.
また、ニゲイモ群は晩生種として品種「石川早生」等の
早生種群の後に市場に出荷され、耐寒性の強い品種であ
る。In addition, the Nigeimo group is a late-maturing variety that is shipped to the market after the early-maturing variety such as the cultivar "Ishikawa Wase," and is a highly cold-resistant variety.

Here, the shoot apex is also called a growing point, and is a tissue with high cell division activity at the tip of the plant body. In the case of taro, it is inside the bud and has a cone shape. This treatment method involves sterilizing the excised shoot apices and treating them with a mutagen, such as methylnitrosourea. Immerse in the solution and treat for 10 to 40 minutes.
この場合容器を振盪すると一層効果的である。In this case, shaking the container is more effective.
