        Potato is an important cash crop of Pakistan and widely cultivated in plains and mountains of Punjab. Khyber Pakhtun Khawa Gilgit Baltistan, on an area of 0.313 million hectares in summer, autumn and spring with an annual production of 07.9 million tons. In Pakistan potato yield is 25.2 tons per hectare, which is although above the world average but comparatively low as compare to the potential and other advance potato growing countries because of several reasons. Availability of healthy seeds and advance production technology are the major constraints to achieve the higher potato production goals. It is very alarming that in spite of good position in potato growing countries, we are unable to produce good quality seed. In Pakistan >01% quality seed is available against the seed demand around 0.5-0.7 million tons per annum and mostly depend upon the imported seed 15000-20000 tons per annum. Tissue culture industry has been a proven global technology in potato seed production, so it is dire need of the growing population and climatic change to adopt these modern technologies of potato production for sustainable and higher production and income to contribute potato growing farmers of Pakistan. It is possible with the commercial use of tissue culture and allied techniques as aeroponic potato seed production along with good management and plant protection measures to provide indigenous high vigor and high yield potential potato seed. Pakistan Agricultural Research Council has established Aeroponic Potato Seed Production facility at National Agricultural Research Center with the collaboration of Korean Govt RDA-KOPIA Pakistan. The Aeroponics is a modern technology for growing plants by providing a nutrient solution in the air without soil. Plants grow rapidly in the growth chamber under the aseptic environment, balanced nutrition and sufficient oxygen availability that improves potatoes production in the aeroponic system. This can produce 10 times more yield than conventional production systems. Aeroponics techniques are credited for making potato yield more efficient, and can reduce the number of steps in the potato seed multiplication. Through tissue culture and aeroponics facilities development in Pakistan, first ever more than 200,000 nucleus mini harvested at NARC from the autumn 2021 and spring 2022 planation at KOPIA screen houses. Further seed multiplication from the harvest is under progress at up hills and more than 500,000 tubers (G1) are expected to be harvested during October-November 2022. It is very encouraging, impressive and successful venture of KOPIA at Pakistan for the potato seed production and self-sufficiency to insure food security in the country.

        The potato production area in Mongolia can be divided into four regions such as central agricultural region, western agricultural region, eastern agricultural region, and gobi agricultural region based on climate and soil conditions. The potato cultivation area increased by over two times for twenty years from 7,806 ha in 1994 to 16,821 ha in 2012. Amounts of potato production also increased by over four times from 53,957 tons in 1994 to 245,935 tons in 2012. The average yield per ha increased by about 8 tons, 15.0 ton/ha in 2012 more than 6.9 tons/ha in 1994. This result is attributed to successful supply of virus-free seed potatoes through the ‘Mongolian Potato Program’ (MPP). The potato import volume decreased dramatically from 35,884 tons in 2008 to under 34 tons in 2013 and the export volume was 3,500 tons in 2013 and 4,800 tons in 2014. Potato breeding program in Mongolia began in the relatively recent years and the important selection criteria were yields, drought tolerance, early maturity, and deep yellow skin and flesh colored variety. The seed potato systems have been improved as follows: traditional clonal selection system(1974-1976), virus free tissue culture system(1988-1990), and MPP seed system( 2004-2008). In the future in Mongolia, combined potato processing facilities are needed for the overproduced potatoes. The official development assistance (ODA) fund being supported for 12 years was stopped along with MPP project termination in 2015, so Mongolia is faced with the difficulty that have to maintain the seed potato system by itself.

        The standard of quality was required to promote the consumption of potato and produce the high quality processing products. It will contribute the stability for processing products and the marketability of potato. The quality was determined based on size of tuber and content of dry matter. Even though the criteria of potato quality was involved many characters of tubers, the most important things were grading and packing of potato to create the consumption. For processing of raw materials, the standard of tubers had create between producer and processor according to size of tuber and content of dry matter. The evaluation of quality was performed over the standard to enhance the control of quality. In addition, the seed potato should be taken the evaluation to disease in the field during the period of cultivation and managed under the strict regulation in storage before release to farmer. Then, the producer of seed potato will make a good relationship to farmer with high quality tubers.
