Journal of Plant Biochemistry & Physiology has placed a article on current issue Title In vitro Evaluation of Somaclonal Variation of Two Potato Cultivars Santana and Spunta for Resistance against Bacterial Blackleg Pectobacterium atrosepticum which deals with,
Recently, tissue culture based in vitro selection have been studied as cost-effective feasible tool for developing stress-tolerant plants. Somaclonal variation created in an experiment conducted with two potatoes (Solanum tuberosum L.) cultivars Santana and Spunta to create somaclonal variation by repetitious subcultures on MS medium for the purpose of evaluating this somaclonal variation for biotic stress resistance, the two cultivars were inoculated in vitro with four concentrates 1 × 102 , 1 × 104 , 1 × 106 and 1 × 108 cfu/ml Pectobacterium atrosepticum. Both cultivars showed significant reduction of disease severity index (DSI) at highest inoculum level 1 × 108 cfu/ml between pre and post subculture. Santana cv. DSI was 51.17% and 61.5% improved significantly to 25.17% and 44.17% for calcium treated and non-treated respectively, while in Spunta cv.
Potato (Solanum tuberosum L.) is one of the major tuber food crop plays a significant role in human nutrition worldwide and contributes to world food security to face hunger. It became the third most widely consumed plant by humans after wheat and rice and recently potato and its processed products have gradually become important trade goods as an important semi-manufactured product. It is an important cash crop widely cultivated throughout the world. Potato is a temperate or continental zone crop and is cultivated in many areas worldwide.
Breeding potato cultivars resistant to Pectobacterium spp. would reduce losses caused by these pathogens. Tubers of potato cultivars vary in their relative susceptibility to Pectobacterium spp. but none of the common cultivars are considered to be highly resistant. Many wild species of Solanum have resistance to Pectobacterium spp. Enjoy reading this article on journal website.
