Germplasm Enhancement for Water Stress Tolerance and Storage Insect Resistance in Bread Wheat (Triticum aestivum L.)
This study was carried out during three successive seasons 2004/05, 2005/06 and 2006/07, to evaluate fifty F derived lines (from the F diallel cross), with three check varieties under two different irrigation regimes. 3 2 Twenty different lines were selected from the fifty F lines under each level of irrigation and evaluated under 3 the same conditions in the F and F generations. Also, the effe...
متن کاملGenetic Diversity and Linkage Disequilibrium in Chinese Bread Wheat (Triticum aestivum L.) Revealed by SSR Markers
Two hundred and fifty bread wheat lines, mainly Chinese mini core accessions, were assayed for polymorphism and linkage disequilibrium (LD) based on 512 whole-genome microsatellite loci representing a mean marker density of 5.1 cM. A total of 6,724 alleles ranging from 1 to 49 per locus were identified in all collections. The mean PIC value was 0.650, ranging from 0 to 0.965. Population structu...
متن کاملCombined Genomic and Genetic Data Integration of Major Agronomical Traits in Bread Wheat (Triticum aestivum L.)
The high resolution integration of bread wheat genetic and genomic resources accumulated during the last decades offers the opportunity to unveil candidate genes driving major agronomical traits to an unprecedented scale. We combined 27 public quantitative genetic studies and four genetic maps to deliver an exhaustive consensus map consisting of 140,315 molecular markers hosting 221, 73, and 82...
متن کاملGenetic Heritability for Grain Yield and Its Related Characters in Spring Wheat (triticum Aestivum L.)
Seven F3 progenies and their 8 parental lines of spring wheat were evaluated for some genetic parameters viz., coefficient of variability (Cv), genetic variance (Vg), heritability percentage (h %) and genetic advance (GA) in 7 quantitative characters (grain yield and its associated traits). Highly significant (p≤0.01) differences were observed for all the characters viz. plant height, number of...
متن کاملGenetic Diversity and Population Structure Analysis of European Hexaploid Bread Wheat (Triticum aestivum L.) Varieties
Progress in plant breeding is facilitated by accurate information about genetic structure and diversity. Here, Diversity Array Technology (DArT) was used to characterize a population of 94 bread wheat (Triticum aestivum L.) varieties of mainly European origin. In total, 1,849 of 7,000 tested markers were polymorphic and could be used for population structure analysis. Two major subgroups of whe...
