Yellow rust, which is a major disease in areas where cool temperatures prevail, can strongly influence grain yield. To control this disease, breeders have extensively used major specific resistance genes. Unfortunately this kind of resistance is rapidly lost due to pathogen adaptation. More-durable resistance against yellow rust can be achieved using(More)
Despite the large impact of powdery mildew in wheat cultivated areas, little has been done to study powdery mildew resistance by QTL analysis up to now. The objective of the present paper is to present how the genetic basis of powdery mildew resistance in the resistant wheat line RE714 have been studied by QTL analysis at the adult plant stage over the(More)
The industrial chicory, Cichorium intybus, is a member of the Asteraceae family that accumulates fructan of the inulin type in its root. Inulin is a low calories sweetener, a texture agent and a health promoting ingredient due to its prebiotic properties. Average inulin chain length is a critical parameter that is genotype and temperature dependent. In the(More)
Assessment of genetic diversity is an essential component in germplasm characterization and utilization. Molecular markers serve as a valuable tool to assess the genetic variation and germplasm identification, which play a key role for faba (Vicia faba L.) bean breeding. In this study, we analyzed the genetic diversity of faba bean accessions based on(More)
Hybrid embryos resulting from crosses between Phaseolus species often fail to reach maturity and some combinations frequently abort at early developmental stages. The genetic or molecular basis for these consistent developmental defects is at present not clear. However, an extremely complex genetic system, thought to be caused by major epigenetic changes(More)
Winter hexaploid wheat (Triticum aestivum L.) was crossed with Aegilops variabilis to transfer resistance to powdery mildew into wheat. Following two backcrosses to wheat and from 5 to 9 generations of selfing, several disomic addition and substitution lines of hexaploid wheat resistant to the mildew pathogen were isolated. A pair of short satellited(More)
Interspecific hybridization in the genus Phaseolus, conducted to introgress desired traits into common bean (Phaseolus vulgaris L.), leads to the abortion of immature embryos, usually at early developmental stages. Little is known about the physiological responses of embryo dysfunction in P. vulgaris during the early stages of embryogenesis and the genes(More)
Two genotypes of common bean (Phaseolus vulgaris L.) were studied to determine the structural cause of seed abortion in this species. In the non-abortive control (wild-type, cultivar BAT93), the histological analysis revealed a classical pattern of seed development and showed coordinated differentiation of the embryo proper, suspensor, endosperm tissue and(More)
Black alder (Alnus glutinosa Gaertn.) is an actinorhizal tree species that is becoming increasingly interesting as a pioneer species and a soil improvement species, as well as for its ecological benefits for river ecosystems and bank stabilisation. Little is known at the molecular level about its genetic variation and population structure. Microsatellite(More)
 A cDNA clone that reveals a high level of polymorphism between wheat varieties was isolated from a wheat cDNA library. When hybridized to DraI-, EcoRV- and HindIII digested DNA this clone, gbx3832, enables us to distinguish 42 different patterns among 48 varieties: 37 varieties are clearly identified, the remaining 11 are divided into five groups.(More)
