Potato (Solanum tuberosum) is a major crop world-wide and the productivity of currently used cultivars is strongly reduced at high soil salt levels. We compared the response of six potato cultivars to increased root NaCl concentrations. Cuttings were grown hydroponically and treated with 0 mM, 60 mM and 180 mM NaCl for one week. Growth reduction on salt was strongest for the cultivars Mozart an...

In order to assess relationship between ion transport and variation in growth responses of four canola cultivars under salt stress, four canola cultivars were grown at 0 and 150 mM NaCl for six weeks in hydroponics. Salt stress reduced the shoot and root fresh and dry weights of all canola cultivars. Maximum shoot fresh and dry weights were recorded in Dunkeld under both non-saline and saline c...

Nematodes produced in monoxenic culture are used for many research purposes. To maximize the number of Heterodera glycines produced in culture, 24 soybean cultivars (maturity groups 0-8) were evaluated for host suitability. A strain of H. glycines race 3, maintained in monoxenic culture on excised soybean root tips of cv. Kent, was inoculated into 20 petri dishes of each cultivar. The highest n...

The olive tree is an iconic tree of the Mediterranean, and is used extensively to produce high-quality olive oil. Although the China olive industry has just begun to be valued, there were also existed mislabeling and synonyms in introduced cultivars. The aim of this study was to analyze genetic similarities among olive cultivars in China using SSR and ISSR techniques. Thirty-two samples were co...

Soybean is one of the most important crops in Brazil and continuously generates demands for production technologies, such as cultivars resistant to diseases. In recent years, the Asian rust fungus (Phakopsora pachyrhizi Syd. & P. Syd 1914) has caused severe yield losses and the development of resistant cultivars is the best means of control. Understanding the genetic control and estimating para...

Abstract The objective of this work was to quantify the extraction and export nutrients by common bean (Phaseolus vulgaris) cultivars from different commercial groups with growth habits. experiment conducted using four cultivars: TAA Gol, BRS FC104, IPR Tuiuiú, Dama. Total dry matter (DM) nutrient accumulation in V4 (with four, six, eight three-leaflet leaves), R5, R7, R8, R9 stages determined,...

ninety barley doubled haploid lines originated from crossing between six barley cultivars in cereal research department, seed and plant improvement institute, karaj, iran were evaluated for resistance to powdery mildew and some agronomic traits in field in 2007. six parent cultivars and a powdery mildew susceptible check cultivar, afzal were also included. sixty two doubled haploid lines showed...

Large portions of the Great Plains and the western U.S. are regularly plagued by drought and diminishing water resources for irrigation. Alfalfa cultivars adapted to these regions, and that can remain productive under reduced irrigation allotments, are clearly needed. This study evaluated the potential of using DNA marker assisted selection (MAS) technology to improve alfalfa forage productivit...
