Verticillium wilt of olive (VWO), caused by dahliae, is a major concern in many olive-growing countries. An efficient VWO control measure the use tolerant/resistant cultivars. Low information available about secondary metabolites and its relationship with tolerance. In this study, comprehensive metabolic profiling roots six cultivars differing their level tolerance/susceptibility to was address...

Two experiments, one site per year, were conducted in Scotland County, North Carolina, to determine the usefulness of selected cultivars and nematicides for limiting soybean losses due to Hoplolaimus columbus. Coker 317 was relatively tolerant to this nematode, and Coker 156, Centennial, Dehapine 105, and Gordon were generally intolerant. Most nematicides significantly increased soybean yields,...

Sweetpotato is an important food, feed and vegetable crop in Niger Nigeria. The adoption of a new variety depends on famers consumers preferences. objective this study was to identify sweetpotato preferred traits by end-users conducted two countries through participatory rural appraisal. results revealed that produced men Niger, while it mostly women South-East In 100% cultivated varieties were...

line yesevi-93 (cultivar abidar) was first introduced to dryland agricultural research institute (dari) through the international winter preliminary barley yield trials (iwpbyt) in 1994. it was selected as one the most high yielding lines based on observational and statistical trails (regional barley yield trials) carried out in different locations during 1997-2000. the average yield of abidar ...

rhizomania (root madness) is caused by beet necrotic yellow vein virus (bnyvv). this disease was first reported fromitalyin 1959 and fromfars,iranin 1996. during the recent years, it has been increasingly developing across the country so that most beet production areas such as khorasan, fars, west azarbaijan,isfahanandkermanshahare now more or less affected by the disease. typically, the taproo...

Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...

Drought and salinity are among the major abiotic stresses which, often inter-relatedly, adversely affect plant growth and productivity. Plant stress responses depend on the type of stress, on its intensity, on the species, and also on the genotype. Different accessions of a species may have evolved different mechanisms to cope with stress and to complete their life cycles. This study is focused...

Aluminum (Al)-tolerance of different cultivars shows considerable differences. Elevation of rhizosphere pH is an external Al-resistant mechanism of plants. To elucidate the correlation between Al tolerance and the capacity of plants to modify the rhizosphere pH at different Al-tolerant levels, a comparative study on the wheat (Triticum aestivum L.) cultivars ET8 (Al-tolerant) and ES8 (Al-sensit...
