  Grain Sorghum, Genotypes, Heterosis, Line X Tester
  Sixteen F1 grain sorghum crosses, its parents (four female lines and four male lines) and one commercial hybrid (Shandaweel-305) as check were evalu-ated for yield and five other characters in 2014 seasons at Arab El-Awamer Res. Station and Shandaweel Res. Station. Randomized Completed Block Design with three replications was used at each location. The obtained data showed signifi-cant orhighly significant differences between locations, genotypes, loca-tionsxgenotypes and location x parents inter actionfor all studied traits except panicle width. Males x females x locations interaction was significant or highly significant for all studied traits. The heterosis values of the better parent ranged from -26.9% in 1000 grain weight to 52.03% in panicle width / plant.Then, the results showed that six crosses were highly significant early flowered than the check and Five crosses were highly significantly out yielded the check 305. The heterosis values of most crosses were highly significant for panicle width, pani-cle length and grain yield more than the best parent.
The female line ICSB-88005 had significantly negative and positive GCA effects for days to 50% flowering and grain yield / plant, respectively. This result indicates that this line had desirable gene action and could be considered good combiners for both traits. Six crosses had negative and significant SCA effects for days to 50% flowering and they were considered to be the best combiners for earliness. One cross (ICSR-93004 x ICSB-89002) showed positive and highly significant SCA for grain yield / plant. The female line (ICSB-88005) had posi-tive and highly significantly GCA effect for grain yield and vice-versa for days to 50% flowering. This line had favorable gene action and could be considered good combiners for both traits.

  Gosssypium barbadense,L., Promising lines, Seed cotton yield, Fiber characters, Heritability, Trial A and Trial B.
  This study aimed to evaluate yield performance of cotton genotypes in dif-ferent environments to know the best genotypes for produce the new variety. Thirty-eight new cotton lines descending from fifteen Egyptian cotton crosses were included in Trail A, and eighteen lines descending from thirteen crosses were included in Trail B in 2014 season using two commercial varieties Giza 80 and Giza 90 as checks. Trail A was raised at Seds, whereas Trail B was held at five locations (Seds, El-Fayoum, El-Menia, Assuit and Sohag) in Middle and Upper Egypt. The results of Trail A showed that the most of genotypes belonging to crosses exceeded significantly the check variety Giza 80 in both yield and its contributing variables. While, Trial B showed the superior of the nine crosses i.e. No. 1([{(G.83XG.80) x Dendara}x(G91xG90)]), 5(G.80 x (G.91 x G.90)), 6(G.80 x (G.91 x G.90)), 7(G.80 x (G.91 x G.90)), 8(G.80 x (G.91 x G.90)), 9([G.83 Radiator x Aust.) x G.91), 14([{(G.83 x G.80) x G.89}x (G.83 x Delt-bain 703)), 15([{(G.83 x G.80) x G.89} x Aust.]) and No. 17([{G.83 x (G.75 x 5844)} x G.80]) surpassed significantly the check variety Giza 90 in seed cotton yield and lint yield, moreover one of them No. 14([{(G.83 x G.80) x G.89}x (G.83 x Deltbain 703)) significantly exceeded Giza 90 in boll weight across five locations. High heritability estimates in broad sense were recorded for most stud-ied traits in Trail A and Trial B indicating that phenotypic selection for these strains could be highly effective. High gcv estimates were observed in seed cot-ton yield (9.66 and 30.08%), lint yield (10.93 and 33.17%) and number of bolls (3.16 and 2.21%) in Trial A and Trial B, respectively. The significant genotypes x locations interaction indicated that, such materials were affected by the envi-ronment and it should further be evaluated for several years at different locations

  fish ball, quality attributes, chemical composition, liquid smoke.
  This investigation was carried out to study the effect of liquid smokes produced from some agriculture wastes as beech sawdust, rice husk, sugarcane bagasse and corncob on the changes of chemical composition (moisture, crude protein, crud fat and ash content) and quality attributes namely: thiobarbituric acid (TBA) value, total volatile basis nitrogen (TVB-N), trimethyl amine nitro-gen (TMAN) of fish ball during chilled storage. The results revealed that the con-trol sample was spoiled at tenth day, whereas the fish ball samples treated with different liquid smoke remained without spoil until 15 day. The results showed that no changes in moisture, protein, fat and ash content of all samples treated with different liquid smokes compared to control sample. TBA, TVB-N, and TMAN in all treated samples with different liquid smokes didn’t reach to deterio-ration levels. All treated samples had lower TBA value, TVB-N, and TMAN contents than that of control sample during storage period. Furthermore, the low-est TBA value, TVB-N, and TMAN contents were noticed in samples treated with rice husk after and during storage periods for15 days, followed by samples treated with beech sawdust, sugarcane bagasse and corncob liquid smoke. Gen-erally, all treatments of fish balls were acceptable by the end of storage period.

  in vitro propagation, grape cvs., shoot tips, nodal segments:
  Successful propagation of in vitro four grape cvs. (Concord, Thompson Seedless, Beauty Seedless and King Ruby) through shoot tips and nodal cuttings was established. The best explants sterilization was achieved with 10% cholorox for 10 minutes. The combination of 1.0 mg/L BA and 0.01 mg/L NAA produced the maximum sprouting rate (100, 91.7, 100, 83.3%) and the least number of days for buds sprouting (6, 9, 5 and 11) of Concord, Thompson Seedless, Beauty Seedless and king Ruby cultivars, respectively. Additionally, the same medium induced the greatest average of shoots number/explants (5.50, 4.95, 5.27 and 4.69) and the highest shoot length (5.3, 5.2, 5.2 and 4.9 cm) for the four tested grape cvs. The third subculture induced the maximum response of sprouting fre-quency and the optimum average of shoot numbers/explants for the four exam-ined cultivars. For rooting of in vitro shoots, Half strength MS medium supplied with 1.0 mg/L IBA resulted in the best root formation (90, 100, 80 and 70%) for Concord, Thompson Seedless, Beauty Seedless and King ruby cultivars, respec-tively.

  : Pomegranates, Antioxidant, Anthocyanin, Soluble solids
  The experiment included three Egyptian pomegranate cultivars namely as Manfalouty, Hejazy and Nab-El-Gamal. The study aimed to assess some physical and chemical characteristics in the fruits and estimate their content of some anti-oxidants at different stages of development.
The study revealed that there were significant differences between the stud-ied cultivars in most traits. The average weight and fruit dimension (length and diameter) significantly increased and reached their maximum values at 165 days after full bloom (maturity stage). Total soluble solids (TSS) and sugars increased while the acidity gradually decreased until they reached the optimum level in ma-turity. Vitamin C concentration increased progressively until the fruits reached their maturity. The total phenolics content (T.P.C) measured in the fruit peel and arils started high, and then there was a gradual decline until they minimized at fruit maturity. Total anthocyanin content of pomegranate arils and peel began low for the three cultivars and gradually increased till the end of fruit develop-ment. Hydrolysable tannin content (as mg tannic acid/ gm of dry weight basis) in peel and lit. of juice began high and rapidly decreased reaching its lowest level at fruit maturity. The differences were significant between the studied cultivars in both seasons for most abovementioned attributes.

  Date palm ,Electrophoresis , Protein pattern
  The study was carried out in Date Palm Research Center Laboratory and College of Agriculture – Basrah University to compare protein electrophrestic patterns for three cultivars of date palm selected for the experiments. Young leaflets were taken from three different cultivars (Ghennamy Al-Akhdar, Samasmi, Khikri) grown in shatt –Al arab - Alfaiha- Iraq. Electrophresis studies showed differences in protein pattern and dinsty and molecular weights. The results indicted that there were differences between proteins in both types and quantities in all three pollen cultivars. Also the results showed that three male cultivars contained one common pand in the same location that has low molecular weight. Al so, results showed the process of differential gen expression has accorded since there were bands, which differed in number. position, and density on the gel in particular male cultivar. There were very distinct differences between of the three male type.

  Harzer-like cheese; milk types; microstructure and sensory evaluation.
  Harzer-like cheese was made from cow’s, buffalo’s, reconstituted milk and skim milk retentate. Submicroscopic structure and sensory evaluation during ripening were studied. The obtained results show that in the early stage of ripen-ing period, the protein network of cow’s skim milk cheese appeared as a large casein fibers, while in buffalo’s milk, cheese was less dense, with open network, casein micelles in reconstituted milk cheese were coalesce and retentate cheese was more compact than other cheeses. After 8 weeks of the ripening period, the extent of hydrolysis of casein in cheese, casein micelle cow’s skim milk cheese fused, formed homogeneous structure. The microstructure of buffalo’s milk cheese was compact with few gaps. Reconstituted milk cheese casein particles counseled together in sheets but retentate cheese had coarser protein network. Finally the disintegration of the casein occurs much faster in cow’s skim milk cheese, with more extensions of aggregated casein micelle than in the other cheeses, and was of good sensory quality.
