Description
Technical field
The invention belongs to field of agricultural cultivation, and in particular to a kind of high starch, the breeding method of high yield Radix Ipomoeae.
Background technology
Radix Ipomoeae (Ipomoea batatas (L) Lam.) belongs to tubular flower mesh, Convolvulaceae annual herb plant, long 2 meters with
On, on prostration ground is oblique, blade is usually width egg shape, long 4-13 centimetre, wide 3-13 centimetre, corolla pink, white, lavender
Or purple, mitriform or funnel-form, long 3-4 centimetre, capsule is avette or oblate, has false dissepiment, is divided into Room 4, has underground tuber, block
Root spindle, crust khaki or aubergine.Radix Ipomoeae rich in proteins, starch, pectin, cellulose, aminoacid, vitamin and many
Mineral is planted, has the reputation of " life prolonging food ".Sugar content reaches 15%-20%.There are anticancer, cardioprotection, prevention emphysema, glycosuria
The effects such as disease, fat-reducing.Ming Dynasty's Li Shizhen《Compendium of Materia Medica》Note has " Rhizoma Dioscoreae esculentae qi-restoratives, spleen benefiting and stimulating the appetite, kidney tonifying are cloudy ", and says marine people
The longevity of food.The traditional Chinese medical science regards Radix Ipomoeae as good medicine.
Traditional Radix Ipomoeae nursery is to adopt vegetative propagation technique, the kind for carrying out year after year using the tendril grown in potato wedges
Plant, yield poorly, content of starch is low, variety deterioration is serious, pest and disease damage is more, poor quality, and utilization rate, commodity conversion rate be not high, mostly
Plant for raise livestock in Around the house.Radix Ipomoeae tissue cultured seedling (detoxification Ipomoea batatas Seedling) can only play a part of to recover original seed, also not
It is the cultivation and breed improvement of new varieties, though there is certain effect of increasing production, is not also the direct utilization of selection cross new varieties.
The content of the invention
