Embodiment 1

[0010] Use 1% HgCl to sterilize the surface of 1 original peanut seed of Huayu No. 30, disinfect it for 15 minutes, rinse it with sterile water for 3 times after disinfection, sow it in a flowerpot filled with sterilized nutrient soil, and put Place the flower pot in the tissue culture room; after the flower grows to 10 leaves, take 8 young peanut leaves, and disinfect the surface of the young peanut leaves with 0.02% to 0.03% HgCl for 15 minutes, rinse with sterile water after disinfection 3 times, cut the rinsed young peanut leaves into 8 leaflet slices of 1.5mm in length and width; put the young peanut leaf slices into the bud induction medium, and the formula of the bud induction medium used was MS+1mg / L 6-BA+ 0.5mg / L 2,4D; enter the elongation medium culture after the end of the shoot induction medium, the elongation medium formula used is MS+0.5mg / L 6-BA; use the rooting medium after the end of the elongation medium culture The culture medium is used for tissue culture, ...

Embodiment 2

[0012] Use 1% HgCl to sterilize the surface of 1 original peanut seed of Huayu 23, disinfect it for 15 minutes, rinse it with sterile water for 3 times, sow it in a flowerpot filled with sterilized nutrient soil, and place the flowerpot Place in tissue culture chamber. After the flower grows to 10 leaves, take 7 young peanut leaves, sterilize the surface of the young peanut leaves with 0.02%-0.03% HgCl, disinfect for 15 minutes, rinse 3 times with sterile water after disinfection, and rinse the young peanut leaves after rinsing. The leaves were cut into 10 leaflet slices of 1.5mm in length and width; the young peanut leaf slices were put into the bud induction medium, and the bud induction medium formula used was MS+1mg / L 6-BA+0.5mg / L 2,4D; After the end of the shoot induction medium, enter the elongation medium culture, the elongation medium formula used is MS+0.5mg / L 6-BA; after the end of the elongation medium culture, use the rooting medium for tissue culture, the rooting ...

Abstract

The invention discloses a method for quickly propagating breeding peanut seeds, which comprises: performing tissue culture of the peanut seeds; slicing young leaves of obtained peanut plants; subjecting the slices to tissue culture in a bud induction culture medium, an elongation culture medium and a rooting medium; and planting the tissue culture seedlings. When the method is used, the propagation factor of a breeding seed is improved by over 6,000 times, the propagation factor of the peanut breeding seeds is improved greatly, the hereditary characteristics of the peanut breeding seeds are retained, and the promotion of high-quality peanut breeding seeds is accelerated.

Description

technical field [0001] The invention relates to a method for rapid propagation of original peanut seeds, and belongs to the technical field of rapid propagation of original peanut seeds. Background technique [0002] Peanut is an important oil crop, economic crop and edible crop in China. my country is the world's largest peanut producer, consumer and exporter. The annual peanut planting area in my country is more than 65 million mu, with an average yield of about 225 kg per mu and a total output of About 14 million tons, my country's peanut industry has made important contributions in adjusting the agricultural industrial structure, increasing farmers' income, earning foreign exchange through export, and ensuring the national oil supply. Since the amount of seeds per mu of large peanuts is generally more than 25 kg, and the amount of seeds per mu of small peanuts is about 20 kg, 10% of the average yield per mu is used for peanut seeds, and the annual seed usage is more than ...
