Evaluation of Indigenous Potato Challisha (Solanum tuberosum L. Cv. Challisha) Somaclonals Tolerance to Salinity In Vitro

Abstract

Potato is one of the most important food crops in the world. It is generally sensitive to salinity and likes to grow in neutral soil. On the other hand, salinity is increasing alarmingly in the ever changing climatic conditions. Thus, the selection of salt tolerant potato cultivars is necessary to keep pace the production of potato. To select salt tolerant cultivars, here we attempt to compare the salinity level between indigenous and modern cultivars. In vitro selection of local and modern potato cultivars were investigated with five levels of NaCl (0, 30, 60, 90 and 120 mM). The indigenous potato Challisha and modern cultivars Diamant and Felsina were used as plant materials. Significant differences were noticed among the cultivars in response to different levels of NaCl. Plant growth and root development were gradually reduced with increased concentration of NaCl. All three cultivars were survived well with exhibiting different growth status up to 60 mM NaCl, but they performed poorly at 120 mM of NaCl. Cultivar Challisha performed better regarding shoot length, root length, the number of nodes per plantlet and the fresh weight per plant up to 90 mM of NaCl. Thus, we can conclude that local indigenous variety Challisha is salt tolerant comparing with the modern cultivated varieties.

Study of Wild and Transgenic Potato (Solanum tuberosum L.) Varieties in In Vitro Condition for Salt Stress Tolerance

“…Accordingly, in a research potato showed reduces growth in response to salinity (Mosavi et al, 2018). Morphological parameters of potato plants were significantly reduced at 120 mM (Biswas et al, 2017) and 150 mM level of NaCl (Efimova et al, 2018).…”

“…In reaction to salt stress, plant activates defense mechanism to survive such as rises the amount of free proline and the level of sugar and Na + accumulation in potato (Daneshmand et al, 2010;Jaarsma et al, 2013;Mosavi et al, 2018), rise in proline contents of tomato (Al-Hassan et al, 2015) and mannitol accumulation in potato (Askari et al, 2012). Level of potato tolerance in salt stress can vary with the variety and cultivar (Murshed et al, 2015;Biswas et al, 2017;Roy et al, 2017). Researchers have explored tolerance level of different potato cultivars and varieties in in vitro conditions as well in vivo (Zhang and Donnelly, 1997;Sudhersan et al, 2012;Biswas et al, 2017;Zaman et al, 2018).…”

Respon Morfologi dan Fisiologi Genotipe Terung (Solanum melongena L.) terhadap Cekaman Salinitas

“…Penelitian mengenai pengaruh cekaman salinitas terhadap pertumbuhan tanaman budidaya terus dilakukan terutama terhadap tanaman pangan dan sayuran yang beberapa di antaranya berasal dari suku Solanaceae seperti cabe (Sharma et al, 2012), tomat (Azarmi et al, 2010), kentang (Biswas et al, 2017), dan terung (Bintoro, 1983;Santoso et al, 2012;Suliasih dan Widawati, 2016). Menurut informasi yang diperoleh dari Ghafoor et al (2004) bahwa ambang batas salinitas tanaman terung sebesar 1.1 dS m -1 dengan presentase penurunan hasil sebesar 6.9% (dS m -1 ) -1 .…”
