METHOD FOR ACCELERATED REPRODUCTION OF POTATO PLANTS USING PHOTOSYNTHESIZING SHOOT METAMERS Russian patent published in 2024 - IPC A01G22/25 A01G7/00 

FIELD: agriculture.

SUBSTANCE: photosynthesising maternal potato sprout formed from the sanitized tuber is transferred into a horizontal position. After bending the apex of the sprout into the vertical position, the first knot from the bend towards the basal part of the sprout is placed in a vessel and isolated from light with a moistened sterile hydrophilic material, thus forming a first light-isolated metamer. With the given parent sprout, the above technique is repeated several times, forming a system of several metamers isolated from light, connected by means of a common stem. With the onset of formation of adventitious roots and lateral sprout on the first metamer, the hydrophilic material is replaced with a nutrient substrate. After formation of an accessory root system and a lateral shoot on the first metamer, the stem of the maternal shoot between the first metamer and the maternal tuber is cut. After formation of accessory root system and lateral shoot on the second metamer, the stem between it and the first metamer is cut, obtaining the first independent metamer, which is a clone of the parent tuber. Cycle of forming new autonomous metamers with their own root system and their own assimilation apparatus is repeated according to the algorithm described above. Obtained clones are used for propagation by the described method, as well as for obtaining a new crop of tubers.

EFFECT: disclosed is a method for accelerated propagation of original planting material of potato plants.
