METHOD TO INCREASE REPRODUCTION FACTOR OF POTATO TUBERS Russian patent published in 2011 - IPC A01G7/00 A01G1/00 C05C9/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of selection and primary seed growing, in particular, to methods of planting stock reproduction. Reproduction factor of potato tubers is increased by stimulation of growth of blanched sprouts by cutting apical part and treatment with a solution of thiourea and sprouting of tubers in the darkness at the relative air humidity of 90-95%. Tubers are sprouted at the temperature of 14-16°C. At the moment of formation of 3-4 nodes at basic blanched sprouts of the primary order the apexes are alienated. As 3-5 side blanched sprouts of the secondary order and sprouts of callus origin form on basic blanched sprouts of the primary order, tubers are planted in soil.

EFFECT: method makes it possible to simplify technologies, to increase rootage, to reduce labour intensiveness with increasing coefficient of potato establishment.
