Fifteen cassava (Manihot esculentaCrantz) genotypes were grown at two field sites of Nigeria from 1994 to 1996 (Ibadan: 28±5°C, altitude 210 masl and Jos: 18±5°C, altitude of 1260 masl) to evaluate the use of chlorophyll fluorescence in screening for cold tolerance in cassava. At 12 months after ...

Two resistance screening assays were developed for evaluating cowpea Vigna unguiculata (L.) Walp resistance to the legume pod borer (MPB), Maruca testulalis Geyer, one of the most intractable pest problems of this important food crop. The first assay, the dual-choice arena test (DCAT), provided a...

A laboratory screening method was developed for evaluating resistance of cowpea, Vigna unguiculata (L.) Walp, to Clavigralla tomentosicollis Stål. The technique uses dry cowpea seeds, which were judged better than fresh seeds or fresh pods, to identify protracted nymphal development and high coho...

The development of resistant crop varieties depends on the reliability of the method of screening for resistance. One of the techniques widely used in evaluating field resistance is the field screening method. However, most cowpea varieties regarded as having field resistance are often found to b...

The burrowing nematode, Radopholus similis, is a serious threat to sustainable banana production worldwide. A promising method for nematode control is the development and deployment of nematode-resistant banana cultivars. This requires the identification of sources of resistance, which can then b...

As research on food crops intensifies in the tropics, the spotlight is being increasingly focused on the development of varieties with resistance to pests and diseases. Much of the time, money and patience needed to conduct research on host plant resistance (HpR) is spent on the development of me...
