Abstract: The present invention relates to a method of evaluating multiple plant individuals or plant lines for deep rooting property under the same culture medium moisture conditions. A method of the present invention is a method of evaluating multiple plant individuals for deep rooting property under the same culture medium moisture conditions, by planting multiple plant individuals together in a sufficiently deep culture vessel and lowering the culture medium moisture content gradually. The present invention also provides a method for evaluating plants for deep rooting property, wherein a culture vessel is installed in a water tank so that the culture medium moisture content can be readily adjusted, and thus management of cultivation conditions is facile and efficient. It is possible to select a plant which can grow in dry and low-groundwater level environment efficiently, by using the method of the present invention.

Abstract: A method for producing potato tubers by hydroponics, by which potato tubers free from lenticel hypertrophy may be produced is disclosed. The method for producing potato tubers according to the present invention is characterized in that a partition member through which roots of potatoes can pass while stolons of potatoes cannot pass is provided above nutrient solution, that the roots are at least partially immersed in the nutrient solution through the partition member, and that the stolons of potatoes are grown on the upper side of the partition member so as to form potato tubers.

Abstract: A large quantity of potato microtubers can be produced easily and in a short period of time by a method of production comprising a first step wherein potato plants are cultured in a medium with a relatively low sugar concentration under a relatively large quantity of light irradiation per day and a second step wherein the resultant potato plants are cultured in a medium with a relatively high sugar concentration under a relatively small quantity of light irradiation per day, the culture in the first step being carried out in the presence of exogenous ethylene and the culture in the second step being carried out in the absence of exogenous ethylene.

Abstract: The present invention relates to a method for producing potato tubers comprising grafting a potato plant as a scion on a solanaceous plant as a stock and culturing the resultant graft plant by hydroponics to thereby form tubers on the aerial part of the graft plant. By the method of the invention, decrease in the ratio of disease infection in tubers as well as reduction of working hours and work intensity are intended.

Abstract: An improved method for producing potato microtubers by tissue culture is provided. The improvement comprises culturing potato plants in a medium containing a high sugar content, i.e., 8% (w/v), for about 1 to 4 weeks under the light prior to culturing the plants in the dark to produce the microtubers.
