A kind of breeding method of blast-resistant pepper seedlings

Abstract

The invention relates to the agricultural technical field, and discloses a breeding method for a blast resistance pepper seedling. The breeding method comprises the steps that first the scions of the to-be-grafted pepper are prepared; then the scions and the stocks are grafted in an oblique abdomen grafting mode; management is conducted on the seedlings after grafting, when the scions grow new buds, the anvils are cut and the pepper grafted seedlings are obtained. During the process of pepper grafting, Piper flaviflorum, the endemic species of China, is the stock, the commonly used splitting grafting mode is changed to oblique abdomen grafting mode, the anvils are cut after the scions grow new buds, the survival rate of grafted pepper seedlings is significantly increased, and the purpose that all grafted seedlings are blast resistant is achieved, pepper blast disoperation is effectively resisted, and the effectiveness of pepper planting industry is improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for breeding blast-resistant pepper seedlings. Background technique [0002] Pepper (Piper nigrum) is a perennial woody vine of the family Piperaceae (Piperaceae). Its fruit has a spicy aroma and is known as the "king of spices". It is the most important spice crop in the world and has medicinal value. and industrial value. At present, pepper has spread to nearly 20 countries and regions in Southeast Asia, Africa, and Latin America, with a harvested area of ​​5.53×10 5 hm 2 , total output 4.33×10 5 t, among them, Chinese pepper is mainly distributed in Hainan, Yunnan, Guangdong and Guangxi provinces, with an annual output of 3.6×10 4 t, ranking fifth in the world. As a popular condiment and a tropical agricultural product with a wide range of uses, pepper has long had the problem of strong demand and insufficient supply. With the improvement of people's living...

AI Technical Summary

Problems solved by technology

At present, the grafting methods used in domestic and foreign reports usually use rootstocks such as South American tree pepper (Piper colubrinum), betel leaf (Piper betle), etc., and use the split grafting method to graft seedlings, but the cultivated pepper seedlings cannot obtain blast resistance. , and the survival rate of grafting is not high

For example, the patent CN103283495A discloses a technical scheme of grafting pepper and betel leaves of wild species of the genus Piper by split grafting, which improves the resistance of the grafted pepper seedlings, but does not acquire the ability to resist blast, and at the same time, it survives grafting. rate up to 80%

There is not yet a breeding method suitable for pepper blast-resistant seedlings
