Twenty-two lines were crossed with 2 testers in a Line × Tester mating design 2017-18 and the resulting 44 crosses along lines, three checks i.e., BARI Hybrid Maize 9 (BHM 9), 981 Elite evaluated alpha lattice two replications, during rabi, 2018-19. Highly significant differences found among genotypes for all characters studied. Parent parents vs except ASI indicating greater diversity parental...

In order to analyze general and specific combining abilities and gene effects in sunflower for some agronomic traits, five CMS lines and four restorer lines (tester) were crossed in a line × tester scheme. Hybrids were evaluated in a randomized complete block design with three replications in the Agriculture Research Station, University of Tabriz, in 2009 and 2010 growing seasons. Plant height,...

Recent studies have revealed that interactions between transcription factors play an important role in regulation of gene expression in eukaryotic cells. To isolate cDNA clones that dominantly inhibit the DNA-binding activity of Oct-2, chosen as a representative factor, we have developed a novel screening system. This employs an Escherichia coli tester strain carrying a modified lac operon as a...

Cotton is most important fiber plant in the world having different properties. This study was carried out to increase yield and ginning outturn of seven interspesific pure (F9) line cotton (G hirsutum L. x G barbadense L.). For this, lines were hybridized with ST 468 Claudia cultivars which belonging genus, 2018, by Line Tester mating design. Then, 14 F1 hybrids sown nine parents according Rand...

to determine the general and specific combining ability of the parental lines, five restorers ‎and four male sterility lines were selected as lines and testers respectively. nine parental lines were ‎crossed in a line × tester crossing system in year 2005 and the eight f1 hybrids and their six ‎parents in randomized complete blocks design (rcbd‏ (‏in two replications for yield, yield ‎component...
