摘要：The present study was carried out to study the in vitro conservation of potato genotypes at different temperatures and aerophilic and micro aerophilic conditions. A total of 31 genotypes were conserved at different incubated temperature ranging from 10 to 25°C. At lower temperature (10°C) plant growth was slowest as compared to plants incubated at high temperature (25°C). The results revealed that aerophilic condition was optimum for the growth of all potato genotypes. Data were collected on plant height, number of roots and number of nodes. Maximum plant height, highest number of roots and number of nodes were observed in all genotypes grown at 25°C. In vitro microareophillic condition of the plant growth was very slow but conservation was maximum. It was concluded from the present investigation that low temperature and micro-aerophilic condition is best for in vitro conservation of International Potato Center (CIP) germplasm which can increase the period between sub culturing.
