Climate change is a major environmental stress threatening biodiversity and human civilization. The best hope to secure staple food for humans and animal feed by future crop improvement depends on wild progenitors. We examined 10 wild emmer wheat (Triticum dicoccoides Koern.) populations and 10 wild barley (Hordeum spontaneum K. Koch) populations in Israel, sampling them in 1980 and again in 20...
Of the various chlorophyll abnormalities that occur in polyploid wheats, genetic bases of only two types, chlorina and virescence, are known. Here, for the first time, the chromosomal bases of three other chlorophyll abnormalities, striato-virescence, delayed virescence, and albino, which occur in Emmer wheat (2n = 4x = 28, genome constitution AABB) are reported. A set of disomic substitution l...
Breeding for solid-stemmed durum (Triticum turgidum L. var durum) and common wheat (Triticum aestivum L.) cultivars is one strategy to minimize yield losses caused by the wheat stem sawfly (Cephus cinctus Norton). Major stem-solidness QTL have been localized to the long arm of chromosome 3B in both wheat species, but it is unclear if these QTL span a common genetic interval. In this study, we h...
Purpose : Plant nitrogen use efficiency can be increased by improving N uptake (NUpE). Root system architecture of the plant plays a vital role in uptaking water and nutrients including N. The present study was conducted to compare root architectural traits different wheat species at early seedling development vegetative growth stage while mature stages under controlled environment.Research Met...
Wheat is undoubtedly one of the world's major food sources since the dawn of Near Eastern agriculture and up to the present day. Morphological, physiological, and genetic modifications involved in domestication and subsequent evolution under domestication were investigated in a tetraploid recombinant inbred line population, derived from a cross between durum wheat and its immediate progenitor w...
