Doubled haploid (DH) populations are useful to scientists and breeders in both crop improvement and basic research. Current methods of producing DHs usually need in vitro culture for extracting haploids and chemical treatment for chromosome doubling. This report describes a simple method for synthesizing DHs (SynDH) especially for allopolyploid species by utilizing meiotic restitution genes. Th...
Analysis of intraspecies diversity in wheat and barley genomes identifies breakpoints of ancient haplotypes and provides insight in the structure of diploid and hexaploid Triticeae gene pools Abstract A large number of wheat and barley varieties have evolved in agricultural ecosystems since domestication. Because of the large, repetitive genomes of these Triticeae crops, sequence information is...
Plant growth can be studied at different organizational levels, varying from cell, leaf, and shoot to the whole plant. The early growth of seedlings is important for the plant's establishment and its eventual success. Wheat (Triticum aestivum, genome AABBDD) seedlings exhibit a low early growth rate or early vigor. The germplasm of wheat is limited. Wild relatives constitute a source of genetic...
Aegilops tauschii (2n=2x=14), the D-genome donor is closest progenitor to modern wheat representing a large proportion of unexplored genetic variation. Flourishing in adverse climatic conditions it can be utilized improvement programmes. We targeted develop and characterize primary synthetics amphiploids from nine different accessions Ae. one Triticum durum cv. PBW114 through spontaneous chromo...
