M.
Hassaan
In order to study the effect of sowing date on performance of hybrids yellow maize, tow field experiment were conducted in two successive summer seasons 2016 and 2017 at the Toshka Experimental station of Desert Research Center, Abu Simbel City, Aswan Governorate. Five sowing dates ( March 1st, March 20th, April 10th, July 20th and August 10th) under studied on the yield and its attributes of four yellow maize hybrids(S.C. 168, S.C. 176,T.W.C.353 and T.W.C. 360 ). Results indicated that sowing date and hybrids significantly affected on plant height, number of grains per row, 1000 grain weight and grain yield kg/fed. The late sowing on Aug. 10thproduced the highest significant parameters of maize plants; plant height, No. of ears/plant, number of raws/ear, 1000-grains weight and grain yields. On the reverse, the lowest values were obtained at medium sown on April10th on sown T.W.C. 360 hybrid was significantly higher than other hybrids in all traits under study in two seasons. The interactions was significant effected on plant height, No. of ears/plant, No. of rows/ear, No. of grains/ear, grains weight/ear and grain yield in both seasons. It could be concluded that sown SC. 176 or SC.168 hybrids during 10th August successfully improving production of maize yield and its components under Toshka conditions.

The current research was conducted in Mansoura University, Faculty of Agriculture at Vegetable and Floriculture Department in the experimental station and tissue culture laboratory of. This study describes in vitro shoot multiplication from the nodal segments of the ornamental and medicinal shrub Snowbush (Breynia disticha). Multiple shoots were induced directly from the nodal explants on Murashige and Skoog (MS) medium fortified with different cytokinins, i.e., 6-benzyl aminopurine (BAP), kinetin (Kin), thidiazrone (TDZ), 2-isopentenyl adenine (2ip) and coconut water at different concentrations individually or in combination with auxins (indole-3-acetic acid, indole-3-butyric acid, α-naphthaleneacetic acid) or gibberellic acid (GA3). BAP at a concentration of 0.5 mg/L was found to be the most effective cytokinin in inducing multiple shoots. Using auxins in combination with BAP was less effective on the frequency of shoot multiplication as compared to BAP alone. While, the frequency of shoot multiplication was markedly influenced by adding GA3 to the media, since the highest percentage of shoot multiplication (100 %) as well as large number of shoots/ explant (4.16 shoots) were obtained with MS medium supplemented with BAP at 0.5 mg/L + GA3 at 0.1 mg/L. Also, this medium succeeded to induce roots at the same stage with rooting percentage of 50 % and roots number of 4.15 roots. Mixture of soil: peatmoss (1: 1) was suitable planting substrate for hardening the rooted shoots and its use ensured high survival frequency (100 %).

Halophiles can be classified as extreme, moderate and slight halophiles. Many extremophiles produce unique biotechnological and commercial materials. Salinity stress is one of the major factors negatively affecting bacterial growth. Cellular biochemical changes could be monitored via protein pattern in response to different NaCl concentrations. So our work aimed to do a comparison among salt-tolerant bacteria in their response to different NaCl concentrations via halotolerance test, antimicrobial susceptibility, amino acid profile and protein banding pattern. From haloterance test of eleven bacterial isolates, STB5, STB8 and Shigella dysenteriae were more tolerance to NaCl. From 16S rRNA gene sequencing, the two isolates STB5 and STB8 were identified as Halomonas caseinilytica and Paraliobacillus quinghaiensis. From 32used antibiotics only 5 antibiotics, cefotaxime, ampicillin, penicillin G, ceftazidime and aztreonam, showed resistance. From SDS PAGE, the appearance or absence of high or low molecular weight bands may be directly associated with the bacterial response to salt. Protein profile of tested halophilic bacteria under different concentrations of NaCl% (0, 5% and 20%) showed variable polymorphism in Halomonas caseinilytica MG199079, Paraliobacillus quinghaiensis MG250199and Shigella dysenteriae. Environment-specific patterns of amino acids profile were observed. Based on the obtained results, it could be concluded that the three organisms Halomonas caseinilytica MG199079, Paraliobacillus quinghaiensis MG250199and Shigella dysenteriae, are extreme halophilic bacteria, they were different in of amino acids accumulation protein profile and in different concentration of NaCl.

A field experiment was conducted for two successive years to investigate the conventional propagation of Rosa hybrida cv.Eiffel Tower using stem cuttings as affected by the growing season of the year, cutting type and the application of indol-3-butyric acid(IBA) at different concentrations. Uniform cutting types ~ 15-20 cm long (apical, median and basal) were collected from the current year growth of healthy mother plants. Then the cutting bases (2-3 cm) were soaked for 20 minutes in different concentrations of IBA (0, 500, 1000 and 1500 ppm) and the lower end of the cuttings were stuck into 14-cm plastic pots filled with a peat: perlite mixture (1:1v/v). The obtained results statistically analyzed by ANOVA showed that rooting percentage of stem cuttings, number of roots and root length varied according to cutting type, concentration of IBA and growing season. The median cutting type was significantly superior to the other types in both autumn and spring seasons. IBA application significantly improved rooting percentage, root number and root length of the treated cuttings comparing to the untreated ones (control). A significant interaction between cutting type and IBA concentrations was observed on most of the characteristics measured during the autumn season only.

Growth of squash plants cv. Eskandarani during winter seasons of 2016 and 2017 under outdoor conditions was significantly enhanced by application of some natural treatments, i.e. seed cold hardening (SCH) at -1̊ C for 12 & 24 hours of exposure period as seed pre-sowing treatments, and salicylic acid (SA) at 100 & 200 ppm, the mineral nutrients (Ca at 250 & 500 ppm and Zn at 50 and 100 ppm and the natural extracts (GCE at 50 &100 g/l and LRE at 5 & 10 g/l) as seed soaking then foliar spray treatments. Since, significant increases in stem length and diameter, leaves number and total area / plant, as well as fresh and dry weights of roots, stems and leaves were obtained with all applied treatments. Meanwhile, significant reduction in the assimilation rate was existed. Besides, different applied treatments obviously increased photosynthetic pigments, NPK, sugars, total carbohydrates and crude protein contents in leaves of the treated plants compared with those of untreated ones. Increases were in parallel to the applied level of SCH, GCE, LRE, SA, Ca and Zn. In addition, GCE at 100 g/l was the most pronounced treatment in this respect, followed by SA at 200 ppm, LRE at 10 g/l, Ca at 500 ppm, Zn at 100 ppm and SCH at -1 for 24 hours of exposure period in descending order. Therefore, the present study strongly admit the use of natural garlic and licorice extracts, salicylic acid and some mineral nutrients as seed pre-sowing treatments not only to improve growth and productivity of squash plants during winter months under outdoors conditions but also to avoid all cautions (regarding both environment and human consumption) for inserting greenhouses production in the agricultural system.

Two field trials were conducted during two successive growing seasons of 2016/2017 and 2017/2018 at Mallawy Agricultural Research Station, Agricultural Research Center, El-Minia Governorate (Middle Egypt) to study the effect of different levels of N-fertilization (160,190 and 220 kg /fed) on yield, yield components and quality of five sugar cane varieties (G.T.54-9(C9), G.2003-47, G.99-103, G.2004-27 and G.2010-7). A split plot design with three replications was used, main plots were represented by five sugar cane varieties (V1= G.T.54-9(C9), V2= G.2003-47, V3= G.99-103, V4= G.2004-27, V5= G.2010-7). The subplots were used for the three nitrogen levels (160, 190 and220 kg N / fed). The results indicated that: 1- Sugar cane varieties and N-fertilization levels exhibit significant effect on all studied traits in both seasons. Promising variety G.99-103 recorded the highest values of stalk hieght, stalk diameter (cm), millable cane ton/fed and sugar yield (ton/fed) in both seasons, while G.T.54-9(C9) variety recorded the highest values of sucrose %, purity% and sugar recovery%, whoever G.2004-27 variety outyielded the highest value of TSS%2- Increasing applied N levels from 160 up to 220 Kg N/fed significantly increased stalk height, stalk diameter(cm), millable cane ton / fed, sugar yield (ton/fed) and TSS (%), while190 Kg N/fed had the highest values of purity% and Sugar recovery%.3- The effect of interaction between sugar cane varieties and nitrogen levels on the studied traits was significant for stalk height in both seasons and purity%, sucrose % and T.S.S. % in plant crop season only. Generally, it could be concluded that under Middle Egypt conditions, it is recommended to inoculate G.99-103 sugar cane varieties with 220 Kg N/fed to maximize the productivity and quality of sugar cane yield.

Giza 179 Egyptian rice cultivar was grown at Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt, in 2014 and 2015 seasons; to study the influence of Cyanobacteria and Azospirillum as bio-fertilizer, foliar spraying with solution of simulative compounds (ascobein , humic acid and water) and three nitrogen levels (100%, 75% and 50% of the recommended chemical nitrogen fertilizer,69 kg N fed-1) on growth, yield attributes, yield and grain quality. The results show a positive effect of chemical N rate, biofertilizer and simulative compounds on crop growth rate (CGR), panicle numbers m-2, 1000-grain weight, chemical ccompositions into milled grain such as protein and nitrogen content as well as grain and straw yields . Combination of 75% of chemical nitrogen fertilizer along with any biofertilizer or stimulating compounds were statistically at par with any combination containing the recommended nitrogen fertilizer (100% N) in the most of previous characters. Thus, it concluded that the application Cyanobacteria or Azospirillum with ascobien with humic acid as stimulating compounds as well as 75% of the recommended nitrogen dose could be used successfully to achieve optimum grain yield of Giza 179 Egyptian rice cultivar with saving 25 % of N fertilizer.

A.
Soliman
Field work and experiments were conducted at Shandaweel Experimental Station at Souhag Governorate, during 2015-2018 seasons. In 2015 season, sixty type plants were selected from the breeding nursery of Giza 90 cotton cultivar that produced sixty progenies (increase A) in 2016. From the latter, 17 families were selected to form (increase B) in 2017, nine elite families were selected and their seed were massed carefully together to form the nucleolus (Breeder's seed) in 2018 season. The results obtained here indicated that, the pure line method in the sense of pedigree selection for annually renewing Giza 90 breeder's seed could prevent genetic contamination. Meanwhile, the selection technique for producing breeder’s seed of Giza 90 cultivar was valid and proved to be effective in holding the true type of the variety.

Line × Tester Analysis for Yield and Fiber Quality Traits in Egyptian Cotton under Heat Conditions
H.
Mahrous
This research was carried out to evaluate the performance of eight Egyptian cotton genotypes and their F1 hybrids under Upper Egypt heat conditions using Line x Tester analysis, during 2016 and 2017 seasons. In addition, to determine the combining ability, heterosis and gene action which control yielding ability and fiber traits. Eight Egyptian cotton genotypes and 15 crosses were evaluated at Shandaweel Agricultural Research Station, Sohag governorate. Analysis of variance indicated that genotypes, parents, crosses and parents vs. crosses were significant or highly significant for all the studied traits, except lint percentage in parents and parents vs. crosses, which were insignificant. The mean squares due to lines or tester (G.C.A.) were significant or highly significant for most of the studied traits. Line x Tester (S.C.A.) main squares was highly significant for most yield traits, while insignificant Line x Tester (S.C.A.) mean squares were found for all fiber quality traits. Regarding mean performance and heterosis, the varieties Giza 90, Giza 95 and Giza 86 were the best parents in yielding ability and gave high yielding crosses under heat conditions, while Giza 45 and Giza 92 were the good parents to produce the best fiber quality crosses. The results of heterosis also showed that seven crosses had positive and highly significant heterosis based on mid-parents in seed and lint cotton yield /plant and number of bolls/plant i.e., (Giza 80 x Giza 90), (Giza 86 x Giza 90), (Giza 86 x Giza 95), (Giza 87 x Giza 90), (Giza 45 x (Giza 90 x Australian)), and (Giza 92 x Giza 90), while the cross (Giza 92 x Giza 95) had better yield and fiber traits. The line Giza 86 was the best combiner for seed and lint cotton yield/plant, number of bolls/plant and seed index, while lines Giza 45 and Giza 92 were the best combiners for fiber fineness, fiber strength and fiber length. The tester Giza 90 was the best combiner for seed cotton yield/plant and lint cotton yield/plant. Four crosses exhibited positive and significant values of specific combining ability (S.C.A.) effects for seed cotton yield/plant, lint cotton yield/plant, lint percentage and number of bolls/plant. The non-additive of genetic variance was larger than additive genetic variance in all yielding ability traits and additive genetic variance was higher than dominance variance for all fiber quality traits. Broad sense heritability (Hb%) was higher than narrow sense heritability (Hn%) for all traits and high heritability estimates in narrow sense were found for all fiber traits.
