WebThinopyrum bessarabicum Savul. and Rayss, which grov^^s on the Black Sea shore in the Crimea, are tolerant to high levels of NaCl. Thus the introgression of genes conferring salt … WebThinopyrum bessarabicum (2n=2x=14, EbEb=JJ) is recognized for its high tolerance to soil salinity and the scab disease caused by Fusarium graminearum. Seven Triticum aestivum/T. bessarabicum disomic addition lines (2n=44=21′′ ABD + 1′′ Eb) developed at the International Maize and Wheat Improvement Center were assayed. Genomic in situ hybridization …

Introgression of salt-tolerance genes from Thinopyrum …

WebHomoeology of Thinopyrum bessarabicum chromosomes with wheat have already been explained in another study carried out by William and Mujeeb-Kazi (1995) WILLIAM, M.D. and MUJEEB-KAZI, A., 1995. Biochemical and molecular diagnostics of Thinopyrum bessarabicum chromosomes in Triticurn aestivum germ plasm. A total of 1775 crosses were made between wheat and Th. bessarabicum and their derivatives, through both crossing strategies (Fig. 1), leading to the generation of 10,321 crossed seeds (an additional 10,387 self- fertilised seeds were also produced). The number of seeds germinated, plants crossed, … See more To develop a FISH karyotype for Th. bessarabicum, mitotic chromosome spreads of Th. bessarabicum were analysed by mc-FISH using the two probes Oligop-pAs-1 and Oligo-pSc119.2-1 (Fig. 2a). Results … See more To identify wheat–Th. bessarabicum recombinants in our crossing programme, metaphase spreads of root-tips from 281 lines spread across BC2, BC3 and BC4 generations, from … See more sc-GISH analysis of wheat–Th. bessarabicum recombinants and structural aberrations was combined with the above genotyping results to establish and/or confirm the order of the markers within each linkage … See more 22,606 SNPs on the Axiom array showed polymorphism between Th. bessarabicum and wheat (Table 2). The SNPs appeared to be relatively evenly spread over all seven linkage groups. The Axiom array was used to screen … See more hyundai farnworth

Characterisation of Thinopyrum bessarabicum chromosomes …

WebThe results suggested that the diploid Th. Thinopyrum elongatum is an important gene pool for wheat genetic improvement. However, the origins of the Thinopyrum genomes and the nature of the genus' intraspecific relationships are still controversial. In this study, we used single-copy nuclear genes and non-denaturing fluorescence in situ hybridization (ND … WebIn this study, we report the development of Thinopyrum bessarabicum-and Secale anatolicum-specific EST-STS markers and their application in tracing respective alien chromatin introgressions in wheat. The parental lines, Chinese Spring (CS), ISR991.1 (CS/ Th. bessarabicum amphidiploid), and ISR1049.2 (CS/ Secale anatolicum amphidiploid), … WebNov 3, 2024 · Abstract. Thinopyrum bessarabicum (2n = 2x = 14, JJ) is an important source for new genetic variation for wheat improvement due to its salinity tolerance and disease resistance.Its practical utilisation in wheat improvement can be facilitated through development of genome-wide introgressions leading to a variety of different wheat–Th. … hyundai farmington nm
