Abstract BackgroundTaAFP (Triticum aestivum L. ABA insensitive five binding protein) is the homology of AFP of Arabidopsis thaliana which was a negative regulator in ABA signaling and regulated embryo germination and seed dormancy. TaABI5 (Triticum aestivum L. ABA insensitive five) gene was seed-specific, and accumulated during wheat grain maturation and dormancy acquisition, which played an important role in seed dormancy. In our previous study, two allelic variants of TaAFP were identified on chromosome 2BS in common wheat, and designated as TaAFP-B1a and TaAFP-B1b. Sequence analysis showed a 4-bp insertion in the 5’UTR region of TaAFP-B1a compared with TaAFP-B1b, which affected the mRNA transcription level, mRNA decay, translation levels of GUS and tdTomatoER, GUS activity, and was significantly associated with seed dormancy in common wheat. ResultsThe results of transgenic wheats showed that: the genotypes of average GI values, plant height, grain weight of hundred and rough of second and third stem node are all significantly more in pUbi-TaAFP-BaS transformed wheat plants than in pUbi-TaAFP-BbS transformed ones, but transcript expression level. ConclusionAbove all dates indicated that the 4-bp insertion in the 5'UTR of TaAFP-B decreased the transcript expression level of TaAFP-B and the PHS resistance, and increased the plant height, grain weight of hundred and lodging resistance in this system of over expression transgenic wheat.

Dwarfing Genes

Norin 10 based dwarfing genes (Rht1 and Rht2) have been widely exploited for increasing the grain yield in bread wheat (Triticum aestivum L.) by improving partitioning of assimilates to grain. Eight semi-dwarf wheat genotypes having either Rht1 or Rht2 dwarfing genes were compared with a tall control named, Kheri (rht) having no dwarfing genes were evaluated at Rajshahi University, Bangladesh for yield and yield contributing traits. Significant differences in grain yield and yield components were observed in genotypes under study showing the effects of dwarfing genes. Genotype Seri 82 (Rht1) and Kanchan (Rht2) had medium plant height of 75.73 and 72.22 cm respectively, highest number of tillers/plant (7.33 and 7.67), highest number of spikes/plant (6.33 and 6.67) resulted the highest grain yield per plant. Because the dwarfing genes not only provide lodging tolerance but also perhaps pleiotropically affected high yield by allowing more tillers to survive. Number of tillers/plant and number of spikes/plant showed very strong positive correlation with grain yield per plant in all the genotypes. Kheri (rht) with highest plant height (95.17cm) reduced number of tillers/plant (4.00) and spikes/plant (3.67) had the lowest grain yield per plant (3.85g). Aghrani possessed significantly the highest number of grains/spike with medium grain yield/plant (5.94g). The degree of relationship varied from genotype to genotype.DOI: http://dx.doi.org/10.3329/pa.v18i2.18075 Progress. Agric. 18(2): 49 - 55, 2007

This research was carried out at the Swerah Research Station –Office of Agricultural Researches during  2014-2015 seasons. The objective of this research was evaluation bread wheat  (Triticum aestivum L.) genotypes ,which concluded 15 pure lines in seventh generation, which developed by half dialld method between 6 parents ,The experiment was conducted using split plot arrangement with RCBD design with three replicates ,The main plots content four seeding rates (120, 160, 200 and 240 kg.ha-1 ), while the 21 genotypes occupied sub plots .The two pure lines S97 and S148 superoired to all other genotypes except A4.10 and Abu-Ghraib  in grain yield which, produced 6.35 and 6.09 t.ha-1 .Increasing seeding rates caused early flowering, increased plant height, biological yield and harvest index. Significant differences were found in all the studied characters due to genotypes and seeding rates interaction. The pure line S148 ,using 200 kg.ha-1 seeding rates produced highest grain yield (7.49 t.ha-1).
