Solution

Father told Rohit that potatoes are not grown from seeds but pieces of tubers. For sowing, the tubers are cut into pieces, with each piece having one or more eyes. It Is a method of vegetative reproduction. The technique is helpful in raising a new crop in about four months. When grown from seeds, the crop requires 15 months to mature. Here human ingenuity has helped in shortening the crop period. The raised crop is of uniform quality. Sexual reproduction is resorted to only when cross breeding and other modifications are to be carried out in research stations.
