In 1970—1975, Khudoyor Yusufbekov developed a scheme for the master plan for development of the Anatoly Gursky Pamir Botanical Garden. To develop the scientific base, expand the areas of the botanical garden and preserve typical biological objects, more than 600 hectares of land in the vicinity of the botanical garden were obtained. In addition, 19 hectares of irrigated lands were connected to the territory of the garden, on the basis of which experimental sections of the Institute's units were organized. During the years of Khudoyor Yusufbekov's direct leadership (since 1965 till September 1990) of the fruit growing laboratory, situated at the altitude of 2700-3500 m, the area dedicated to the collection of global flora increased by 7 times, and the collection itself increased by 10 times, up to 4000 species and subspecies. The collections of plants in the garden are arranged according to geographical principles, and the irrigated territory is divided into 5 floristic departments: Central Asia and East Asia, Europe and the Caucasus, North America, the Himalayas, and the Hindu Kush. Inside the departments, the plants are arranged in generic complexes, taking into account ecological features of the species. In accordance with specifics of the objects of research in the garden, three groups were formed: dendrology, fodder and medicinal plants, and floriculture. The main task of the Pamir Botanical Garden was the introduction of plants. It exchanged seeds of highland flora and planting material with 112 gardens inside the USSR and 118 gardens from 39 major botanical centers of Europe (East Germany, West Germany, Norway, Denmark, the Netherlands, Czechoslovakia), North America (Canada and the United States), and other countries of the world. In 1972, a pumping station was built, thanks to which the waters of the river Shahdara raised to a height of 180 m. This enabled expanding the irrigated territory from 22 to 118 hectares at an altitude of 2140-2360 m, by over 5 times. The area of 4 floristic departments increased by 2 — 4 times. A laboratory, residential buildings, and the road and irrigation systems inside the garden of the Institute were built.
