In India seed production is being done by well-developed seed plot technique.Growing seed potato crop during low aphid period with healthy seed from October to first week of January coupled with the use of insecticides, rouging and dehaulming in the last week of December or up to second week of January, was developed by the CPRI, Shimla and is called as “Seed Plot Technique” (fig). Potatoes can be grown from true potato seeds (TPS) which are collected from the berries of the potato plant. The process of seed potato certification involves field inspections throughout the growing season, to check for disease and to ensure that varieties are true to type, as well as a winter grow-out of the seed, to screen for disease contamination. A seed-plot technique has been developed on a pilot scale to increase on-farm availability of quality seed potato. TPS is mainly used to develop new potato cultivars and now gaining popularity to raise the commercial crops. Seed produced from a tuber unit plot is classified as Primary Foundation 1. The cost of tuber used in conventional method of planting is high however, the production of tuberlets in nursery for planting in coming season is relatively low. True potato seed (TPS) is a matured ovule of potato resulting from sexual fertilization. Seed tuber is the single most important factor in potato cultivation and if the seed is not of good quality, then optimum production could not be achieved. It is entirely a new technique of seed production in potato which can replace the tubers using as seed instead for using as food. The cost required for storage of huge bulk of conventionally used tubers is higher which is reduced as tuberlets (small in size) require very small space for storage. The ware crop from seedlings tubers can be raised following the standard agronomic practices of the area, keeping in view that smaller tubers are to be planted at closer spacing. Conventional certified seed potatoes are initiated by clonal selection and the tuber unit technique on a primary foundation seed farm.
