Article Information The aim of the study was to investigate the extent of the genetic diversity among gene bank accessions of Ethiopian tetraploid wheat (Triticum turgidum L.) landraces using microsatellite markers, qualitative and quantitative data. Thirty five accessions of Ethiopian tetraploid wheat (T. turgidum L.) landraces were grown in the greenhouse at IFA Tulln, Austria during spring 2...

Abstract Triticum monococcum L. and T. boeoticum L., diploid wild relatives of bread wheat ( aestivum L.), possess resistance to leaf rust (also known as brown rust) caused by Puccinia triticina Eriks. Haustorium formation-based mechanisms (i.e. pre-haustorial post-haustorial resistance) have been studied reported in various accessions. In the present study, mechanism accessions was using confo...

The USDA-ARS National Small Grains Collection (NSGC) maintains germplasm representing global diversity of small grains and their wild relatives. To evaluate the utility of the NSGC durum wheat ( L. ssp. ) accessions, we assessed genetic diversity and linkage disequilibrium (LD) patterns in a durum core subset containing 429 lines with spring growth habit originating from 64 countries worldwide....

Hulled wheats are neglected crops that have potential in plant breeding programmes of modern durum and common wheat. Among these wheats, three species were widely cultivated in Spain until the mid 20th century: Triticum monococcum ssp. monococcum (einkorn), Triticum turgidum ssp. dicoccum (emmer) and Triticum aestivum ssp. spelta (spelt). One important aspect of wheat grain quality is starch co...

To ascertain genetic diversity, population structure and linkage disequilibrium (LD) among a representative collection of Chinese winter wheat cultivars and lines, 90 winter wheat accessions were analyzed with 269 SSR markers distributed throughout the wheat genome. A total of 1,358 alleles were detected, with 2 to 10 alleles per locus and a mean genetic richness of 5.05. The average genetic di...

Genetic diversity in breeding programs can be impaired by fixation of alleles derived from a limited number of founder lines. This is demonstrated with the use of a solid-stem trait derived from the Portuguese landrace 'S-615' over 70 yrs ago that is widely used to resist the wheat stem sawfly ( Norton, WSS) in North America. The objective of this study was to evaluate haplotype diversity under...

The National Bioresource Project-WHEAT (NBRPWHEAT), launched by the Japanese government in 2002, aims to maintain and distribute seed stocks and DNA clones of “Wheat”. The second-term NBRPWHEAT started in 2007. Additionally to its primary roles in handling seed stocks and DNA clones, the second-term NBRP-WHEAT features the collection and characterization of DNA markers, which will make the seed...

in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...

Pearl millet (Pennisetum glaucum (L.) R. Br.) and napier grass (Pennisetum purpureum Schumach) are the most economically important species in the genus Pennisetum. Knowledge of genetic diversity of these two species would enhance their potentials for utilization. The present work assessed the genetic diversity and phylogenetic relationship among Nigerian and Indian accessions of pearl millet an...
