The potato tuberworm, Phthorimaea operculella Zeller (Lepidoptera: Gelechiidae), is a serious pest of the potato, Solanum tuberosum L. (Solanales: Solanaceae), in both fields and stores in tropical and subtropical regions. In the present study, the susceptibility of different potato cultivars to P. operculella was evaluated by measuring life table parameters. Tests were undertaken with leaves a...
Salt-tolerant mutants of potato (Solanum tuberosum L. ‘Marfona’) were obtained via gamma irradiation. Node explants of the Marfona potato plant were treated with various dosages of gamma irradiation, and the M1V2 and M1V3 clonal generations were developed. Selection of salt-tolerant mutants was accomplished by in vitro selection media containing 50, 100, and 125 mM NaCl. Molecular-level diff er...
the potato tuberworm, phthorimaea operculella (zeller) (lepidoptera: gelechiidae), is one of the most damaging pests of cultivated potato (solanum tuberosum l.) crop, in both field and stores in tropical and subtropical regions. the biological parameters of this pest were evaluated in the growth chamber at 24±1ºc, 65±5% rh and photoperiod of 14:10 h (l:d) on leaves of ten potato cultivars, agri...
To obtain a higher percentage of callogenesis and consequently the maximum number of plantlets, one of the most important procedures for transgenic plant production. To this end, a factorial experiment using completely randomized design (CRD) with four replications was carried out to assess the effect of cultivar (Marfona and Agria), type of explants(leaf and internode), Kanamycin concentration...
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 ...

In order to determine the best nutrient solution and potato cultivar for minituber production in aeroponics and comparison with classic hydroponics, a factorial experiment with three factors of culture system (aeroponics and hydroponics), nutrient solution (Chang et al., APCoAB and commercial nutrient solution of Isfahan), and different potato cultivars (Marfona, Santana and Moren) was carried ...
In order to investigate the effect of effect of date and depth of tuber cultivation on some agronomic traits of potato cultivars in autumn and spring cultivations, a split factorial experiment was carried out based on randomized complete blocks design with three replications in Ardabil Agricultural and Natural Resources Research Station during the two cropping year 2017-2018. Planting date as t...
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 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 ...
