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).

Abstract A field experiment was carried out in Samawa desert (70 km west of Samawa city, Al-Muthanna governorate), during the 2018-2019 and 2019-2020 agricultural seasons, to study the response of three Iraqi cultivars of wheat (Tamooz2, Ibaa99, Abu Ghraib3) to three planting dates (November 15, 1st December and December 15) under Samawa desert conditions. The results showed the superiority of Tamooz2 cultivar in all traits of the yield components, it gave the highest averages of grain yield, which amounted 5.75 and 5.89 tons/ha−1, weight of 1000 grains, which amounted 29.79 and 31.06 gm, and the number of grains per spike, which amounted 73.02 and 73.76 for the 2019 and 2019-2020 seasons, respectively. The date of December 15th also surpassed in the traits of grain yield, weight of 1000 grains, number of spike grains, and the highest grain yield reached 5.62 and 5.58 tons/ha−1 for the two seasons 2018-2019 and 2019-2020, respectively, and the combination (Tamooz 2 x December 15) gave superiority over the other combinations in terms of grain yield which amounted 6.05 tons ha−1 (2018-2019 season) and Ibaa99 × December 1 gave the highest grian yield about 6.10 tons ha-1 (2019-2020 season).
