Genetic Behavior for Reverse Thermo-Sensitive Genic Male Sterility (RTGMS) through Segregating Generations of some Rice Genotypes in Egypt
FIFTY populations selected from F2 for two crosses i.e. cross I (M.J. 5460 S × Sakha 106) and cross II (M.J. 5460 S × GZ7768) were planted as F3 generation in 2013 season and twenty populations were selected from F3 and planted as F4 generation in 2014 season. The selected populations were studied for reverse thermo-sensitive genic male sterility (rTGMS) trait, some growth and yield traits were measured. The F4 populations means were lower than the means of F3 populations only in the days to heading trait while, F4 means were higher than F3 means in the other studied traits. These data indicated the improvement for most studied traits by selection. High heritability was estimated in broad sense for all growth and yield traits in both crosses as F3 and F 4generations. Heritability in narrow sense ranged between 35.79 % for number of tillers trait in cross I as F3 generation to 74.95 % for days to heading trait in cross I as F3 generation. The highest genetic advance from selection as percentage of mean (Δg %) was 63.72 for yield per plant trait in cross II in F4 generation. Molecular studies indicated that, the RM222 as specific SSR primer revealed the presence of one specific band with molecular size of (200 bp) with M.J 5460S line as reverse thermo-sensitive genic male sterile line which indicated that, this band may be related to reverse thermo-sensitive genic male sterility gene. It could be concluded that RM222 as specific SSR primer could be used to identify the rtms1 gene in reverse thermo- sensitive genic male sterile lines, which could be used in japonica hybrid rice seed production u nder Egyptian conditions.

Molecular Diversity Assessment among Commercial Egyptian Rice Varieties
The current study was carried out at Rice Biotechnology Lab, RRTC, during 2016-2017G to estimate the genetic diversity of eleven commercial rice varieties at the molecular level. Sixteen sequence-related amplified polymorphism (SRAP) and Eighteen Inter-Simple sequence repeats (ISSR) were used to access the molecular diversity. The studied varieties included 7 pure Japonica, 2 pure Indica and 2 Indica Japonica varieties. SRAP primers generated a total of 579 bands with average of 36.19 bands/primer pair across tested genotypes. The number of amplified genetic loci (alleles) ranged from 4 to 8 with a total of 85 alleles across all tested primers. The polymorphic alleles ranged from 3 in ME6xEM4 to 7 alleles in ME4 x EM7 and ME8 x EM8 primer combinations. The PIC values ranged from 0.645 to 0.859 with overall PIC value of 0.776. UPGMA-based clustering of the eleven commercial varieties separated the studied varieties according to their genetic background. The pure Japonica group, Pure Indica group and the Indica/Japonica group. The eighteen ISSR primers generated 897 amplified bands with average of 49.72 bands/primer. A total of 132 alleles were assessed that ranged from 4 alleles in ISSR11 and ISSR13 to 12 alleles in ISSR18. The overall PIC value was higher than that of SRAP primers and recorded 0.830. Although ISSR system successfully separated the three different groups, the subgroups arrangement on the dendrogram varied. The results showed the existence of considerable amount of molecular diversity among commercial varieties. Both marker systems showed high resolution power in assessing diversity, however, SRAP results were more aligned with varietal genetic background. The study suggests also the possible reliance on molecular marker systems in assessing genetic diversity.

Effect of Using Slow-Release Urea on Milk Production and its Composition of Lactating Dairy Cows
Twelve lactating Holstein cows with live body weight from 550 to 680 kg averaging 600 ± 15 kg and at 1-4 of lactation seasons were used in Latin square design (3x3) with three treatments and three successive experimental periods. Cows in G1 were fed the basal ration consisted of (on DM basis) 57.7% concentrate feed mixture (CFM) + 24.7% corn silage (CS) + 17.6% alfalfa hay (AH) without supplementation and served as a control. While, in G2 and G3, 1 and 0.5 kg soybean meal was replaced by 125 and 62.5 g Optigen™ plus 2.710 and 1.355 kg corn silage/ head/ day, respectively. Results showed that the contents of DM, OM, CP, NFC and NFE in experimental rations tended to decrease, however, the contents of CF, NDF, ADF and ash tended to increase with increasing the level of Optigen supplementation. The digestibility coefficients of all nutrients and nutritive values were not significantly affected by Optigen supplementation. Average daily intake of total DM, TDN, CP, DCP, DE, ME and NEL were nearly similar for the different experimental rations. Moreover, average daily yield of actual milk and 4% FCM, milk composition, the concentrations of urea and urea-N in milk, the concentrations of urea-N and total protein in blood plasma, feed conversion ratio, daily feed cost, feed cost /kg milk and economic efficiency were not affected significantly (P>0.05) by Optigen supplementation. It could be concluded that optigen supplementation for lactating Holstein cows did not showed any significant effects on feed intake, digestibility, milk yield and composition along with feed conversion ratio and economic efficiency.

Impact of Biological Agents and Plant Essential Oils on Growth, Quality and Productivity of Cabbage and Cauliflower Plants Correlated to Some Diseases Control
Control of the plant diseases using chemicals is one of the most important issues for vegetable crops because of the accumulation of harmful residues of these chemicals sometimes causing serious problems for both human health and agroecosystems. Therefore, a field experiment was carried out during two successive winter years 2014 and 2015 on cabbage and cauliflower plants at Sakha Horticulture Research Station Farm, Kafr El-Sheikh Governorate, Egypt. Different effects of bio-control agent microorganisms and some essential oils on growth, yield, quality and reducing damping-off disease of cabbage and cauliflower plants were recorded. Seven treatments including Bacillus subtillus, Trichoderma harzianum, eucalyptus oil, spearmint oil, clove oil, Rizolex T50 (fungicide) and control were arranged in a randomized complete block design with three replicates. Results revealed significant differences among various growth attributes, total head yield (ton/fed) and head quality due to essential oils and microorganisms. Also, microorganisms and essential oils under field condition improved transplants survive and reduced the damping-off disease incidence as compared to untreated control. Moreover applying of Trichoderma harzianum and Eucalyptus oils seemed to be superior in improving vegetative growth, total head yield with large and heavier heads. As well as, using of clove oil, Trichoderma harzianum and Bacillus subtillus increased shelf life period and decreased cabbage head weight loss percentage, while the superior treatment of cauliflower was Trichoderma harzianum compared to control.

This study was carried out during the two successive growing seasons of 2014 and 2015 on eight years old Washington navel orange trees budded on sour orange rootstock grown in a private orchard located at Shino village, Kafrelsheikh governorate, Egypt, to evaluate the effects of some soil amendments and GA3 foliar application on vegetative growth, nutritional status, yield and fruit quality as well as soil properties. The experiment was arranged in a randomized complete blocks design with eleven combination treatments as follows: (T1) control or untreated trees, (T2) mycorrhizae at 15g/tree/year, (T3) mycorrhizae at 15g/tree /year + sulphur at 1kg/tree /year, (T4)mycorrhizae fungi at 15 g/tree/year + Nile fertile at 750 g/tree /year, (T5)mycorrhizae at 15 g/tree/year + bio-tol at 2 cm/l was sprayed from Feb. up to May, (T6)mycorrhizae + sulphur + 30 ppm GA3 was sprayed at full bloom stage, (T7)mycorrhizae + Nile fertile + 30 ppm GA3, (T8) mycorrhizae + bio-tol + 30 ppm GA3, (T9) phosphorine (bio-fertal) at 11 g/tree/year + Nile fertile, (T10) Phosphorine + bio-tol + 30 ppm GA3 and (T11) phosphorine + sulphur + 30 ppm GA3.The results indicated that trees treated with T11 had remarked effect followed by T7than the other treatments in most of vegetative growth parameters (canopy volume, leaf area, leaf dry weight and specific leaf weight, at the spring growth cycle) and increased leaf chlorophyll and mineral contents in both seasons. T11 followed by T10, T9, T8 and T7 achieved the best fruit yield and fruit quality compared with untreated trees. Soil pH and salinity (EC) were decreased while available macronutrients (N, P and K), soil microorganisms content and dehydrogenase activity were increased with applying T11, T10, T9, T8, T7, T6 and T5 comparing with control (T1). Therefore, both T11 and T7 treatments are recommended for citrus orchard to improve growth, yield and quality as well as soil properties and comforting higher return for orange trees growers under Kafrelsheikh governorate conditions.

Study of Wheat Response to Nitrogen Fertilization, Micronutrients and their Effects on Some Soil Available Macronutrients
The present investigation was carried out in the Experimental Farm of Faculty of Agriculture, Kafr El-Sheikh University during the two successive winter growing seasons of 2012/2013 and 2013/2014 in the same location to study the long term effect using one variety of wheat (Triticum aestivum L.), cv. Masr 1.The experiment was conducted in split-split plot design, with four replicates. The main plots were randomly assigned to nitrogen levels (0, 40 and 80 kg N/fed), the sub plots were represented by the two chelated forms of humic and EDTA as foliar application and the sub-sub plots were represented by four micronutrients spraying of Fe, Cu, Mn and Zn, each one in two concentrations.The objectives of the present study were to investigate the effect of different levels of N and foliar application of some chelated micronutrients on: (1) grain yield and yield component of wheat plant (2) uptake of N, P and K by wheat under different treatment of N rates and micronutrients and (3) some soil available macronutrients.The results showed that, the best treatments were N80, Zn2 and Mn2 which gave the highest production for wheat grain and straw yield which indicate the importance of balance fertilization for wheat crop. These results also indicated that, improving soil fertility and replenishment nutrients depletion under the conditions of the present study could be achieved using previous treatments.

An Economic Study of the Production and Consumption of Vegetable Oils in Egypt
The plant oils are one of the most important consumer goods. The vegetable oils are produced, in Egypt, from multiple sources. the most important of them are the seeds of cotton, soybeans, oily rotary sun flower. Egypt is suffering, for a long time, that there is a chronic and growing shortfall in domestic production of vegetable oils on the consumer's ability to fulfill the requirements of this item which has led to low self-sufficiency in vegetable oils ratio of up to 14.4% in 2015. Of course, this situation may be due to a decrease in the planted area year after year, in addition to the increase in consumption resulting from the increase in population, changing consumption patterns, and increasing health and nutritional awareness. The research problem represented in this gap exacerbated year after year, which led to the adoption of the state to import from abroad to fill that gap. The targeted of the research is mainly to study the production and consumption of vegetable oils in Egypt during the period )2000-2015. The research has adopted on the analytical and descriptive approach, and the methods of statistical analysis, relying on the published and unpublished data from Official agencies and international information network during the period )2000-2015(. The research found the following results:The results of the study of productivity indicators for the most important oilseed crop in Egypt pointed to the fluctuation in both the planted area, the productivity per acre and the total production of all crops: cottonseed, sunflower seeds, and soya seed oil, which reflected the general trend of decreasing for each crop, certainly morally or upwardly. The results of the study of the relative impact variables on the planted area and the productivity per acre on the total production pointed to outweigh the horizontal expansion option in the three crop production than the vertical expansion option of choice. According to a study of economic factors affecting the production of vegetable oil in Egypt: the outweigh of the profitability pound spent on summer crops competing oil crops which indicates the reasons for the reluctance of farmers for the cultivation of oil crops and thus lower the total planted area and production of seed and oil. The results of the study of economic indicators for the production and consumption of vegetable oils in Egypt noted: that self-sufficiency in vegetable oils is decreasing annually by 1.07% represents about 4.4% of the annual average for the period of research, which is equal to a 24.1% rate. While for factors affecting the consumption per capita of vegetable oils in Egypt, it has been demonstrated that the average annual pound income per capita and the quantity of imports of vegetable oils during the search period by thousands of tons are the most important factors affecting the average annual consumption per capita of vegetable oils.
