Potato tuber necrotic ringspot disease (PTNRD) is a tuber deformity associated with infection by the tuber necrotic strain of Potato virus Y (PVYNTN). PTNRD negatively impacts tuber quality and marketability, and poses a serious threat to seed and commercial potato production worldwide. PVYNTN symptoms differ in the cultivars Waneta and Pike: Waneta expresses severe PTNRD and foliar mosaic with...
in order to study the seasonal population fluctuations and density of aphid species (vector of potato viruses) in hamedan province during 1999–2003, four important potato-growing areas (hamedan, kaboudarahang, asadabad, and ghahavand) were studied using, yellow water traps. among collected aphids, four species belonging to aphididae and one to drepanosiphidae were identified in potato fields. i...
A study was conducted in 2009/2010 cropping season in order to determine energy input/out put and productivity of potato and sugar beet production systems in Isfahan province, Central Iran. The data used in this study was based on data collected from growers by using a face to face survey. Total energy consumption and total out put enegy in potato production systems were calculated to be about ...
Two crop growth experiments in the soil-based closed ecological facility, Laboratory Biosphere, were conducted from 2003 to 2004 with candidate space life support crops. Apogee wheat (Utah State University variety) was grown, planted at two densities, 400 and 800 seeds m-2. The lighting regime for the wheat crop was 16 h of light-8 h dark at a total light intensity of around 840 micromoles m-2 ...
The present investigation was conducted to develop a protocol for rapid plant regeneration in potato. The newly emerge sprout of six potato cultivars were used as explant. Varietal response on in vitro regeneration under different hormonal concentration and combination were studied. MS medium supplemented with 0.5, 1.0, 1.5, 2.0, 4.0 mg L of KIN and IAA in combination of both were employed for ...
