Results of potato varietieis for drought tolerance in vitro conditoin

Abstract

The laboratory’s experiment conducted at IPAS in 2017. The goal of this study was to evaluate drought stress tolerance of released potato varieties using PEG-6000 in-vitro condition. Middle maturing variety Gala, early maturing Solist and Quarta were used experiment. The objectives were to determine how osmosis pressure affected potato plantlet height, root length, total weight of biomass, and stem diameter using their index comparing to normal condition. The screening experiment used three different treatments. The water stress treatments 0 MPa (control), -0.05 MPa and -0,15 MPa were created by PEG-6000. 6 weeks’ year’s old plantlets were measured by 5 features. The variety Gala showed significant high index by 5 performances among the stressed condition compared to Quarta and Solist. The variety Quarta also showed high performance compared Solist. As a result of this study found out that cultivar Gala more tolerant to drought than Quarta and Solist.
