A field experiment was conducted at the field of the Dept. of Field Crop Sci. / College of Agriculture / University of Baghdad . The objective was to determine the values of relative constant of three – way and double crosses of maize . Ten inbreds were used and crossed during spring and fall seasons of 2009 to produce three - way and double crosses , and ten hybrids were taken from each group . The ten hybrids were grown and selfed during spring 2010 to produce F2 seed . Three way and double crosses were sown with their parents and F2 seed during fall 2010 in RCBD with four replicates . Leaf area , total dry matter , row/ear , grain/ear , grain weight and grain weight/plant of hybrids , parents and F2 plants were taken . Results showed that the relative constant obtained was applicable to estimate F ̅2 of hybrids . However , leaf area was different in values of F ̅2 , as compared to that observed in the field . The relative constant values were different as trait and parent number of crosses differ . The obtained relative constant of grain weight/plant was (0.576) and (0.556) , grain weight (0.521) and (0.516) , grain /ear (0.571) and (0.554) , raw / ear (0.509) and (0.502) , total dry matter . plant -1 (0.553) and (0.541) and leaf area (0.508) and (0.495) in three way and double crosses , respectively . It was concluded that the application of relative constant , to predict parent means (P ̅), F ̅2 and parent number (n) was fit as compared to Wright's equation [ F ̅2= F ̅1 – (F ̅1 - P ̅)/n ] . Accordingly , it was recommended to use the formula [F ̅2 = χ (F ̅1 + P ̅)] to predict F ̅2 of hybrids , [(P ) ̅= ( F ̅2 / χ ) – F ̅1] to predict P ̅, and [ n = ( F ̅1 - P ̅ ) / ( F ̅1 - F ̅2 ) ] to predict number of inbreds included in the hybrid .

A field experiment was conducted at the field of the Department of Field Crop Science, College of Agriculture University of Baghdad during two winter successive seasons of 2007 2008 and 2008 2009. The objective was to study the effect of sowing dates 510, 1510, 511 and 1511 on two cultivars of common caraway (Iraqi) and Balady (Egyptian). RCBD was used under factorial experiment with three replicates. Results showed that the second date (15/10) was superior in volatile oil yield of 32.21 and 32.44 l.h-1, for each season, respectively. Iraqi cultivar gave significantly higher volatile oil yield of 27.44 and 29.07 l.h-1. GC/FID method separated 11-13 terpenoid components. They had different RIs by differing of sowing dates and cultivar. Sowing of Balady at 15/11 gave highest RI of carvone of 59.82%.while sowing common Iraqi cultivar at 15/10 gave highest RI of limonene of 55.12%. GC/MS separated 23-29 compounds from common Iraqi cultivar and 31-32 compounds from Balady. Sowing common Iraqi cultivar at 15/10 gave highest RI of carvone of 71.49%. Sowing of Balady at 5/11 was superior in RI of limonene of 38.12%. It was concluded that the best sowing date was the second one (15/10) , the best cultivar was common Iraqi cultivar and the best separation method was GC/MS. Therefore, it recommended to sow Iraqi common upto 15/10 and use GC/MS method to separate volatile oil components.

A laboratory experiment was conducted during 2011 at the laboratories of the Faculty of Science at the University of Plymouth in UK, to determine the germination capacity of bread wheat seeds (Triticum aestivum L.) for five cultivars (Fateh, IPA 99, Sham 6, Clare, and Caxton) under the effect of three temperatures (10, 15 and 20 ºC). A completed randomized design with four replications was used. The results showed that the cultivars IPA 99 and Fateh were superior in the percentage of germination in the first count (FG) 92.5, 93.2 % and final count (FIG) 97.0, 98.8 %, coefficient of velocity of germination (CVG) 37.8, 35.5 %.d-1, mean germination time (MGT) 2.8, 3.0 d and germination rate index (GRI) 38.5, 36.9 %.d-1. The temperature 20 ºC was superior in FG 83.1 %, CVG 38.7 %.d-1, MGT 2.7 d, GRI 37.9 %.d-1, RL 10.5 cm, PL 8.3 cm and SDW 0.0121 mg. IPA 99 and Sham 6 were superior under the three temperatures 20, 15 and 10 ºC in FG. The interactions (Sham 6 × 20 ºC) and (IPA 99 × 20 ºC) were superior in MGT, GRI and PL. A significant positive correlation was found between FIG and between each of FG 0.652, CVG 0.324 and GRI 0.533, while a negative correlation was found between MGT and between each of FG -0.869, FIG -0.343, CVG -0.950 and GRI -0.925. It can be concluded that the cultivars IPA 99 and Sham 6 are suitable for sowing in areas with low temperatures during the germination stage and should be investigate the potential performance and ability of seeds of IPA99 and Sham 6 under field condition.

The study was carried out at biotechnology laboratories- GCSAR- Syria in summer season-2010. The random amplified polymorphic DNA (RAPD) based on Polymerase Chain Reaction (PCR) with ten primers were applied, used to estimate fingerprinting and Genetic Distance for six cultivars of Rosa spp. (Tea R., Musk R. , Hybrid perpetuls R. , Climber R. , Miniature R. , French R.). Phases of work included the isolation and purification of DNA plant parts and DNA polymorphisms were scored within amplified fragements by electrophoresis. The results of RAPD analysis were clear differences in the number of DNA amplified fragments and molecular weights depending on the primers user . A total number of polymorphic amplified 68 fragments for all primers used . Genetic Distance for rose cultivars genetic variability found in it. High Genetic Distance Rose cultivars (40.3%) in RAPD markers was registered between the two cultivars (Hybrid perpetuls R. X Climber R.) and lowest Genetic Distance (18.9%) between (Tea R. X Climber R.). Rose cultivars gave genetical and morphological variations confirmed by genetic distance. High genetic differences between rose cultivars could be attributed to the geographical locations they were grown as well as plant breeding made to it.

The aim of this experiment was to search the behavior of Zn-HA fertilizer in soil in Zn availability and its uptake by wheat comparing with (Zn-DTPA) and the metal sources (ZnSO4 .7H2O) in addition to control treatment. Incubation experiment to study physio-chemical behavior of the three fertilizers Zn-HA, Zn- DTPA, and ZnSO4.7H2O when added to soil in a normal condition by following-up. The available zinc over time and how zinc may affect by soil properties by using six kinetic equations (using Buch equilibrium technique) and their statistical parameters(r2 and SEe). In this part of study, an equal quantities of Zinc of 50 ppm from (ZnSO4 .7H2O, Zn- DTPA , and Zn-HA sources to soils and left to react for periods of 0, 14, 28, 56, 84, 98, 112, 126, 140, and 154 days with two replicates for each treatment. The results were showed that available zinc declined by 31.4% when Zn- HA fertilizer added as an average in incubation experiment, while this decline was greater over time when metal source of Zinc was added ZnSO4 .7H2O and recorded as 94.3% as an averages. The treatment of second degree-type exponential decay succeeded in describing available zinc over time. The amount of loss of added zinc from the industrial chelating source( Zn- DTPA) and natural chelating ( Zn-HA) were only 43% and 33% in the biological experiment as an average, treatment of second degree-type exponentional decay was superior in describing the available zinc over time ) 1/Ct = 1/Co + kt ). As for the Zinc uptake by wheat plant over time. Results indicated that the amount of Zn uptake increased with time by 626.7 µg.pot -1. When Zn- HA added as an average. While the value was less when Zn- DTPA and ZnSO4 .7H2O added and reached 548.2 and 444.6 µg.pot -1 respectively. The lower amount of uptake was with control treatment by 147.3 µg.pot -1. To determine the relationship between zinc uptake over time, the first order equation type exponential; Ct = ln Co-k t was the best equation successive to describe the relation.
