ABSTRACT
Potato tubers as a valuable food product for most people in the world are considered “second bread.” Agricultural environment of mountainous areas of Tajikistan situated at an altitude of more than 1800 m above sea level makes it possible to grow good and quality harvest of potato. Under these cool mountainous conditions, potato plants are of little affection, have intensive bloom, and form a lot of berries and botanic seeds.
Thus, on basis of above researchers work analysis and our experience on potato crossbreeding obtained in India on 2009, for the first time in the highland of Tajikistan we have begun to research the rate of pollen grain fertility and to cross different grades and hybrids of potato and the results of this researchers brining in this article.
Among cultivated potato varieties Cardinal grade has the least percent of fertile pollen grains—26.5% and the new perspective Dusti grade has the greatest percent of those—95.2%. As a result of potato varieties and 102hybrids crossings, 6 kg of hybrid berries has been obtained which seed will be sown and studied in the future.
Our research works in Tajikistan direct to selected new clones of potato tolerant to high temperature and drought weather in the future for support of rural farmers in global climate change situation.
