Responses of Various Spring Wheats to Vernalization.
There is little information in the literature regarding North American varieties of spring wheat which are responsive to vernalization treatment. The same variety has been reported by different investigators to react positively or negatively to treatmenit. For example, VAN HOEK (3) obtained acceleration of maturity when springof wheat was vernalized, but treatmelnt of the same variety by GMELIN...
متن کاملEvaluation and characterization of high-molecular weight 1D glutenin subunits from Aegilops tauschii in synthetic hexaploid wheats
The high-molecular weight (HMW) glutenin subunits of bread wheat are major determinants of end-use quality. The objective of this study was to determine the 1Dx and 1Dy subunits present in 43 synthetic hexaploid wheat (SHW) lines derived by crossing durum ‘Langdon’ to 43 Aegilops tauschii accessions. Protein samples were initially electrophoresed multiple times on SDS-PAGE gels to arrange subun...
متن کاملCharacterization of greenbug (Homoptera: Aphididae) resistance in synthetic hexaploid wheats.
Twelve greenbug (Schizaphis graminum (Rondani)) biotype E-resistant synthetic hexaploid wheats synthesized by crossing Triticum dicoccum Schrank. and Aegilops tauschii (Coss.) Schmal. were evaluated for the three known insect resistance categories, including antibiosis, anti-xenosis, and tolerance. Different methods were evaluated for calculating antibiosis and tolerance. Calculating intrinsic ...
متن کاملCharacterization of HMW-GS and evaluation of their diversity in morphologically elite synthetic hexaploid wheats
High molecular weight glutenin subunit composition and variation in 95 Elite-1 synthetic hexaploid (SH) wheats (Triticum turgidum/Aegilops tauschii; 2n = 6× = 42; AABBDD) were determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis method (SDS-PAGE). Twenty two different alleles at Glu-1 loci in SHs were observed. Forty four different patterns of HMW-GS in synthetics were found...
متن کاملRAPD and SSR based genetic diversity analysis of elite-2 set of synthetic hexaploid wheats.
BACKGROUND Synthetic hexaploid wheats are artificially reconstituted hexaploid wheats that possess high genetic variation which could be utilized for the development of new improved wheat varieties. One such group of synthetic wheats is called the Elite-II set of synthetic wheats that are derived from crossing durum wheat with different Aegilops tauschii wheats. MATERIALS AND METHODS In the c...
