Characterization 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 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...
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 کاملStudy of Genetic Diversity in Synthetic Hexaploid Wheats Using Random Amplified Polymorphic Dna
Ten Synthetic Hexaploid Wheats (SHWs) (2n = 6x = 42, AABBDD) were analyzed using 7 Randomly Amplified Polymorphic DNA (RAPD) primers to investigate the potential genetic diversity resided within the D-genome of common wheat. Total 190 fragments were amplified in which 141 were polymorphic showing 74 % of polymorphism. Polymorphism Information Content (PIC), Genetic Similarity (GS) Coefficient, ...
