“…Table (8) shows means of planting dates the first date was superior to the second date with a significant difference and a mean of 40.22 gm, while it did not differ significantly from the third date that gave a mean of 39.30 gm they cause to environmental factors temperature and light period stages of plant growth that determine the size of flower and amount of increased or decreased final grain weight, this finding is consistent with [18], as they found differences between planting dates in a 1000-grain weight trait, as for genotypes results showed the superiority of FRAH genotype with a mean of 47.71 gm with a significant difference from some genotypes and taking MO-HAND genotype the lowest mean for this trait was 31.87 gm which did not differ with some other genotypes while the rest of genotypes were taken to differentiate between the highest and lowest mean the reason for increase and decrease is due to genetic factors of each composition on ability or inability of plants to provide growth rates for grain which leads to an increase or decrease in weight of grains this finding is consistent with [19], finding significant differences between genotypes of a weight 1000 of grain trait. As for the comparison of means of interactions between dates and genotypes, it showed the superiority of genotype POPP-CAAL at the first date with a mean of 58.07 gm a significant difference from all other interaction factors as for genotype MOHAND at the second date it gave the lowest mean of 23.85 gm the increase or decrease in weight of 1000 grain, had It is due to the appropriateness or inappropriateness of environmental factors from the temperature and light duration of different growth stages and extent of their influence on the accumulation of dry matter that is reflected in the weight of grains.…”

In this study, 20 genotypes of triticale (RWAIDA, AMAL, MOHAND, FRAH, POLLMER, LIRON, HUI/TUB, HUI/TUB-1, CENT/1715, BW32-1-1, CMH80, CMH82, POPP-CAAL, CAAL, LIRON -1, LIRON -2, LIRON -3, LIRON -4, LIRON -5, and LIRON -6) were used the experiment was planted according to the design of randomized complete block design by the split-plot arrangement the plant dates putting in main plot (5 November, 20 November, and 5 December), and genotypes in subplot the results show: the first date exceeded the grain yield per plant, number of spikes per plant, number of grains per spike, weight 1000 (g), as it reached 17.16 gm plant-1, 5.91spike, 86.33 grain, and 40.22 gm respectively. The LIRON-2 genotype was superior in the number of spikelets per spike with a mean of 40.15 and number of grain per spike with a mean of 97.28 and yield of grain with a mean of 18.71 gm plant-1 and the genotype of LIRON-3 in some spikes with a mean of 5.64 and biological yield of 47.65 gm plant-1.

The main aim of this study was to determine the optimum line of triticale (X Triticosecale Wittmack) and best location for cultivating. The experimental design used in this study was randomized complete block design with two replications. In this study 29 lines of triticale were applied to assess some agronomic character (Plant Height (cm), No. of Days from Seeding to 50% Anthesis, No. of Days from Seeding to Physiological maturity, No. of Days from 50% Anthesis to Physiological maturity, No. of Fertile Tiller/Plant ), yield character (Grain Yield (t/ha), Biological Yield (t/ha) and Harvest Index). Plowing methods were used twice for the area of the study in each region. In Qlyasan region sowing started on 21 December and on 25 December in Halabja region. A total of 29 triticale lines developed from the hybridized winter triticale lines were used with a set name of 41ITYN and was taken from The International Maize and Wheat Improvement Center (CIMMYT). The 29 triticale lines consisted of (802, 803, 804, 805, 806, 807, 808, 809, 810, 811, 812, 813, 814, 815, 816, 817, 818, 819, 820, 821, 822, 823, 824, 825, 826, 827, 828, 829 and 830). The result illustrated that ) the maximum plant height, No. of Days from Seeding to 50% Anthess, No. of Days from Seeding to Physiological maturity, No. of Days from 50% Anthesis to Physiological maturity and No. of Fertile Tiller/Plant was observed in lines (804, 809, 830, 827 and 807). The highest agronomic character was observed under cultivation of triticale in the Halabja location. The maximum Grain Yield (t/ha), Biological Yield (t/ha) and Harvest Index was observed in lines (802, 828 and 827). Cultivation of the plant in Halabja region also gave the highest yield.

“…By distant hybridization, the crop species triticale (× Triticosecale Wittmack) was created, and highly productive commercial varieties for various purposes were obtained 3 . Triticale is an alternative crop for areas characterized by low soil fertility as well as uneven and late rainfall 4 . However, the implementation of sustainable farming is impossible without obtaining new varieties of triticale that meet the requirements of modern farming 5 , 6 .…”

Major chromosome rearrangements in intergeneric wheat × rye hybrids in compatible and incompatible crosses detected by GBS read coverage analysis

The presence of incompatibility alleles in primary amphidiploids constitutes a reproductive barrier in newly synthesized wheat-rye hybrids. To overcome this barrier, the genome stabilization process includes large-scale chromosome rearrangements. In incompatible crosses resulting in fertile amphidiploids, the elimination of one of the incompatible alleles Eml-A1 or Eml-R1b can occur already in the somatic tissue of the wheat × rye hybrid embryo. We observed that the interaction of incompatible loci Eml-A1 of wheat and Eml-R1b of rye after overcoming embryo lethality leads to hybrid sterility in primary triticale. During subsequent seed reproductions (R1, R2 or R3) most of the chromosomes of A, B, D and R subgenomes undergo rearrangement or eliminations to increase the fertility of the amphidiploid by natural selection. Genotyping-by-sequencing (GBS) coverage analysis showed that improved fertility is associated with the elimination of entire and partial chromosomes carrying factors that either cause the disruption of plant development in hybrid plants or lead to the restoration of the euploid number of chromosomes (2n = 56) in the absence of one of the incompatible alleles. Highly fertile offspring obtained in compatible and incompatible crosses can be successfully adapted for the production of triticale pre-breeding stocks.
