Two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. The minitubers were evaluated for several quality characters. The plant materials were from three cultivars, Agria, Marfona and Savalan. The plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...

the use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (solanum tuberosum l.) micropropagation and adventitious shoot formation. three potato cultivars (agria, marfona and savalan cultivars) were examined for their growth response with medium containing four different levels of kno3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...

abstract: colorado potato beetle (cpb), leptinotarsa decemlineata (say),is the most important insect pest of potato in iran. if local potato varieties vary in susceptibility to the pest, host plant resistance may provide management benefits to potato growers. a life table study was carried out to determine the relative suitability of four common potato varieties (agria, marfona, savalan and sat...

The potato tuber moth (Phthorimaea operculella Zeller) (PTM) is a destructive pest. Bacillus thuringiensis cry genes encode crystal proteins that have toxic characteristics against PTM. aim of the present study was to develop PTM resistant cv. Agria using synthetic Bt cry1Ab gene. transformation vector constructed by inserting gene into pBI121 binary expression vector. Agrobacterium tumefaciens...
