Abstract

10 Genotypes of bread wheat (Triticum aestivum L.) were planted arranged in sequence (1) Abu Ghraib (2) Cowes (3) Osis (4) Sit Mall (5) Florca (6) Clack (7) Milan (8) Hedab (9) Abaa 99 and (10) Sham. In addition to their interchanged mid-crosses, their number (45), Obtained from crosses between parents without reverse crossbreeds, These structures were planted to study (parents + first-generation hybrids) in Diyala Governorate – Baldruz District, for the agricultural season (2017-2018) and using the design of (RCBD) and with three replications and traits (number of days to expel spikes and Plant height is cm, leaf area (cm2), number of grains per spike, number of spikes/plant -1, the weight of 1000 grains (g), individual plant yield (g), biological plant yield (g), it was found that the parents and their hybrids differed significantly for all traits. The study studied and the hybrid (7 × 9) showed a desirable hybrid strength for most of the studied traits from the average parents and the best parents, while the hybrid (2 × 6) showed a desired hybrid strength in four traits, including the grain yield as a deviation from the best parents. Sovereign variation, which was reflected in the degree of sovereignty, as it reached more than one correct one for all traits, which confirms the superior sovereignty that controls its inheritance, and that the proportion of the dominant and recessive alleles is less than 0.25%, meaning that it does not show the regular distribution in the sites that show dominance and that the degree of heritability in the narrow sense is less than 20%, which confirms its lack of importance Additional variability of the genetic sites that control the inheritance of these traits.

Abstract

The study gathers 56 samples of waters, Sediments, bones of some Living being as well as some plants available in local markets (vegetables and fruits) taken from different areas of the south Iraq governorates to determine radon concentration  222Rn emitted from the chosen samples and the generating radioactive radium 226Ra resulted from the dissolution of the period  Jan – March 2019. It manipulates the active measure method of the electronic speeder through the use of the Rational Application Developer RAD7 and the passive method, the long-term method for radiation of alpha particles, utilizing Solid State Nuclear Track Detectors (SSNTDs) technique and Two types of detectors were used; CR-39 and LR-115-typeII. The results show that the greatest concentrations of radon in waters 16234±1014Bq/m3 in Shatt- El-Arab waters in Basra while the least concentration 2153±134Bq/m3in Al-Turbia station in Thiqar, whereas the highest radon concentration 20570±1285Bq/m3 is of a sample taken from the Sediments if Al- Msab_el_aamin the north of Basra. As for the concentration in living beings, the highest is of a sheep bone 4869±304 Bq/m3 from Basra (Northern Rumaila); the least is of a chicken bone 132±8 Bq/m3   taken from local markets in Misan. The planet samples show that the highest radon concentration 128± 8Bq/m3 is fenugreek from Basra markets and the least is of an apple exported in Misan markets. The annual estimated dose affecting water is1.60mSvy-1 Which is greater than the worldly permitted dose, which is 1mSvy-1. Generally, it is found that radon concentration of the chosen water samples from the South of Iraq is greater than the permitted ratio, 11Bq/L and its concentration in Sediments also records a noted increase which may cause danger for population health living in these areas.

Abstract

This study was conducted in the laboratories of the Palm Research Center of the University of Basrah. The study studied the effect of different concentrations of seawater (0, 10, 20, 30, and 40%) and different concentrations of Salicylic acid (0, 50, and 100 mg / L) (MS) with a concentration of 4.6 g / l to add some amino acids and some vitamins and use of NAA at a concentration of 10 mg / L and  2,4.D at a concentration of 20 mg / L. The results of the study showed that increased seawater in the medium increased In the concentration of amino acid proline and phenols and significantly reduced In the total carbohydrate either increased the concentration of salicylic acid has led to a significant increase in total carbohydrates and phenols and significantly reduced in the amino acid proline. As for the effect of seawater on the actual antioxidant enzymes, the results of the present study showed that its increased concentration in the medium resulted in a significant increase in the effectiveness of SOD, CAT, and APX enzymes and significantly reduced the effect of enzymes (PO and GR) salicylic acid increased in the medium to a significant increase in all enzymes studied.

Vol.6 No.5 – 1: Economic analysis to factors affecting the production of fish farms – mud ponds in the province of Diyala for the season of 2018

ABSTRACT 

     The study examined the production function of the fish farms in the Diyala Governorate for the season 2018 through a questionnaire prepared for this purpose, questionnaire (31) fish products were selected from (61) products while (27) farms were not working out of the total, Multivariate analysis was carried out by taking the natural logarithm of production as a dependent factor and the natural logarithm of the productive resources as independent factors. The analysis revealed the importance of conservation and irrigation costs, fish feed and prevention costs and the cost of purchasing and transferring the fingerlings. These resources were positive elasticities, while the analysis proved the significance of the labour resource of the elasticity was negative. The analysis of the regression of both capital and land and labour using the model (Cup – Dogalas) to determine the overall elasticity of production and the analysis proved the significance of these resources were positive elasticities, which means that these resources gave the optimal combination in the model (Cup – Douglas). The descriptive analysis also revealed the lack of government support for these farms and the lack of hatching stations. It was recommended that government support for fish producers such as providing hatching stations and activating agricultural extension to raise awareness of farmers at the prices of production inputs and applying the results of scientific research to farm management. Production to diversify farmers’ income and make use of available resources.
