Using cereal crops as examples, we review the breeding for tolerance to the abiotic stresses
of low nitrogen, drought, salinity and aluminium toxicity. All are already important abiotic …

Heterogeneous environments make it difficult to apply consistent selection pressure
because often it is difficult to identify a single or a few superior genotypes across all sets of …

Drought is a wide-spread problem seriously influencing wheat (Triticum aestivum L.)
production and quality, but development of resistant cultivars is hampered by the lack of …

Breeding has been very successful in generating cultivars that in favorable environments,
and together with large use of fertilizer and chemical control of weeds, pest and diseases …

Application of physiological and biochemical indices as a screening technique for drought
tolerance in wheat genotypes Page 1 African Journal of Biotechnology Vol. 7 (14), pp. 2341-2352 …

Drought and low soil N cause significant yield reductions in maize (Zea mays L.) grown in
the tropics. Understanding the genetic basis of hybrid performance under these stresses is …

Wheat improvement for drought tolerance requires reliable assessment of drought tolerance
variability among segregating populations. One hundred and fifty-one F3 and F4 families of …

The difficulty of choosing appropriate selection environments has restricted breeding
progress for abiotic stress tolerance in highly variable target environments. Genotype-by …

Most maize (Zea mays L.) in the tropics is grown under low‐nitrogen (N) conditions, raising
the need to assess efficient breeding strategies for such conditions. This study assesses the …

It is not known whether selection for improved tolerance to a specific abiotic stress leads to
correlated changes in performance under other stresses. Drought and N deficiency are …
