Embodiment 1

[0044] 1) Ultra-low temperature treatment of purple potato tubers:

[0045]Take purple potato tubers with good appearance, healthy and disease-free, and exercise them at a low temperature of 0-2°C for 7 days, then perform ultra-low temperature treatment at -185°C for 0.5 hours, and then thaw and restore the purple potato tubers in the later stage.

[0046] 2) Induction culture of seed potato root tip and shoot tip:

[0047] Take the purple potato tubers with excellent appearance after recovery and culture and bury them in sterilized sand for cultivation. The sterilized sand environment is 15-17°C in temperature and 61-65% in humidity. After 5-8 weeks, it grows roots and new shoots. Induction culture of root tip and shoot tip;

Abstract

The invention provides an efficient breeding method of purple potato tissue culture seedlings. The efficient breeding method of the purple potato tissue culture seedlings comprises the following steps of treating purple potato tubers at ultralow temperature; performing induced culture on root tips and stem tips of seed potatoes; performing rooting culture on strong seedlings, and conducting virus detection on test-tube plantlets; performing induced culture and virus detection on miniature potatoes; performing transplanting and cuttage grafting breeding on the miniature potatoes. According to the efficient breeding method of the purple potato tissue culture seedlings, provided by the invention, miniature potato seedlings are bred by adopting virus eradication of stem tips and root tips; the culture cycle of the root tips is different from that of the stem tips; the root tips and the stem tips are jointly cultured, so that the time cost can be effectively reduced, seed potato resources are fully and efficiently utilized, and further the reproduction cost of the tissue culture seedlings is reduced; besides, the test-tube plantlets cultured by using the root tips are high in reproduction speed, so that the working efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to plant tissue culture rapid propagation technology, in particular to a high-efficiency propagation method of purple potato tissue culture seedlings. Background technique [0002] Purple potato is an annual crop of Solanaceae, native to Australia. Purple potatoes, also known as black potatoes, are oblong in shape and have smaller bud eyes. The peel is dark purple, jet black and shiny, rich in luster. The flesh is dark purple, good-looking and attractive in color. The pulp starch content is as high as 13-15%, and the taste is good and the quality is excellent. According to the determination: every 100 grams of black potatoes contains 2.3 grams of protein, 0.1 grams of fat, 16.5 grams of carbohydrates, 11 milligrams of calcium, 1.2 milligrams of iron, 64 milligrams of phosphorus, 342 milligrams of potassium, 22.9 milligrams of magnesium, 0.01 milligrams of carotene, thiamine 0.1 mg riboflavin, 0.03 mg riboflavin, 16 mg niacin. ...
