Pre-harvest sprouting (PHS) resistance is one of the most important traits in wheat breeding. Characterization of Viviparous-1 (Vp-1) haplotypes in wheat related species will further our understanding of the role of Vp-1 in PHS resistance of bread wheats. The present paper reported Vp-1 haplotype analyzes of 77 accessions of wheat related species including T. monococcum and T.boeoticum (AmAm), T....
Pre-harvest sprouting (PHS) greatly reduces the quality and economic value of wheat grain. In this study, a total of 168 International Maize and Wheat Improvement Center (CIMMYT) wheat germplasm lines were examined to characterize the haplotypes of Vp-1A, Vp-1B and Vp-1D, which are located on the long arms of chromosomes 3A, 3B and 3D, respectively. Among them, five new alleles of Vp-1Aa (the wild...
Malnutrition or ‘hidden hunger’ severely stunts human potential due to imbalanced diets and a lack of vital vitamins and minerals. Hunger and obesity are its extremes. Hardy, multipurpose legumes that can be used as vegetables or grains by smallholders or large enterprises and with multiple manufacturing uses have a vital role to play in overcoming growing malnutrition in South Asia, Africa, and the...
Pre-harvest sprouting (PHS) of wheat greatly reduces the quality and economic value of grain, and PHS tolerance is one of the most important traits in wheat breeding. Two new Vp-1B alleles were identified in wheat genotypes with distinct PHS tolerance and ABA responsiveness and designated as Vp-1Bb and Vp-1Bc. These alleles had an insertion of 193-bp and a deletion of 83-bp in the third intron in...
Pre-harvest sprouting (PHS) reduces the quality of wheat (Triticum aestivum L.) and the economic value of the grain. The objective of this study was to evaluate the diversity of the Viviparous-1B (Vp-1B) gene associated with PHS tolerance in a collection of 490 widely grown winter wheat varieties from central and northern Europe. Four alleles of Vp-1B were found in the wheat varieties tested, three...
The high molecular weight glutenin subunits (HMW-GS) are important components of storage proteins in common wheat (Triticum aestivum L.). Conventional techniques for identifying the HMW-GS apply SDS-PAGE. To study differentiation of the HMW glutenin genes, partial DNA sequences of the concerned alleles were characterized from eight accessions of hexaploid synthetic wheat and common wheat varieties,...
Almost two-hundred random sequence decamer-primers were used to screen a pair of bulked samples and the donor parent Malus floribunda clone 821 for markers linked to the Vf gene conferring resistance to apple scab (Venturia inaequalis (Cke.) Wint.). A single primer was identified which generated a PCR fragment, OPK16/1300, from the donor parent M. floribunda clone 821 and the scab-resistant selections/cultivars...
