The present investigation was carried out during 2015/2016 and 2016/2017 seasons at the Experimental Research Station, Faculty of Agriculture, Assiut University. The objectives of this investigation were to obtain information about the performance and genetic components of parental wheat genotypes and their F1s under normal and water stress conditions. The performance of all genotypes under water stress condition was lower than its performance under normal condition. The parent 6 (P6) was the earliest flowering under both conditions and the parent P5 under water stress condition (85.70 day), while the parents P1, P2,P4 andP6 gave the tallest spike under both of normal and water stress conditions. While, P1 and P2 gave the tallest spike under water stress condition. The hybrids (P4 × P5) and (P1 × P6) were the earliest among F1- hybrids under normal and water stress conditions, respectively. Furthermore, the hybrids (P1 × P3) and (P1× P4) gave the tallest spike under normal and water stress conditions, respectively. The mean of grain yield /plant for all genotypes was 32.70 g and 24.96 g under normal and water stress condition, respectively. The P6 gave the highest grain yield/ plant compared with other parental genotypes under both conditions. On the other hand, the highest grain yield /plant was obtained from the hybrids (P4 × P5) under both conditions. The results showed that the magnitude of SCA exceeded GCA ones for days from planting to 50 % heading trait, which indicating that the major portion of genetic variance was due to the non-additive gene effects. The ratio of GCA/SCA was noticed to be low for days from planting to 50 % heading trait, indicated the specific combining ability was more important than general combining ability variance. The ratio of GCA/SCA was low for Plant height except SCA under irrigation in the F1- hybrids. The ratio of GCA/SCA was 1.08 and 0.80 in the F1-hybrids under normal and water stress conditions, respectively. The good genotypes for plant height in the F1- hybrid under both environments were Entry 21 and Entry 20. While, the ratio of GCA/SCA was noticed to be low for spike length, indicated the specific combining ability was more important than general combining ability variance, which indicating that the major portion of genetic variance was due to the non-additive gene effects. The results showed that the magnitude GCA/SCA ratio for number of kernel/spike was 0.31 and 0.20 in the F1-hybrids under normal and water stress conditions, respectively, indicating that the non-additive were larger than additive effects in the inheritance of number of kernel/spike and both were highly significant. The ratios of GCA/SCA were less than the unity for grain yield/plant under both environments indicating that the non-additive gene action controlled the inheritance of grain yield/plant. The GCA/SCA ratio was 0.14 and 0.48 for 100-grain weight in the F1-hybrids under normal and water stress conditions, respectively, indicating predominance of non-additive gene effect in the inheritance of 100- grain weight

Impact of Silicon and Humic Acid Application under Water Stress Condition on some Bread Wheat Cultivars and Some Soil Properties
تأثیر استخدام السیلیکون وحمض الهیومیک تحت ظروف الإجهاد المائی على بعض أصناف قمح الخبز وبعض خصائص التربة
Wheat (Triticum aestivum L.) is widely cultivated in the Mediterranean zone where plants generally suffer from water stress during heading and reproductive stages. This research was carried out in a field experiment at Shandaweel Agricultural Research Station during the two successive growing seasons 2015/2016 and 2016/2017 using water treatments (water stress and well watered) and humic acid (soil application) and silicon (foliar application) on some wheat cultivars (Gemmeiza 11, Shandaweel1, and Sids 12). The application rate of humic acid and silicon was 2Kg/feddan and 150 ppm, respectively.

Molecular Genetic Markers for Tissue Culture Response in Garlic (Allium sativum L.)
الواسمات الجزیئیة الوراثیة والاستجابة لزراعة الأنسجة فی الثوم
Five genotypes of garlic (Allium sativum L.), namely Balady (G1), Chinese (G2), Sids-40 (G3), Egaseed-1 (G4) and Egaseed-2 (G5) were used for assessing tissue culture response, genetic variability and polymorphism amongst which and to identify molecular markers associated with tissue culture response using ISSR and SRAP techniques. Significant differences were found among the five genotypes, the concentration of growth regulators as well as the interaction between them for all measured tissue culture traits. The Euclidean-distance dendrogram using tissue culture data separated the five garlic genotypes into two clusters; the first cluster comprised the highly responsive genotypes (G1, G2 and G3) while the less responsive genotypes (G4 and G5) grouped together in the second cluster.

Equality Prices for Wheat in Egypt
أسعار المساواة لمحصول القمح فی مصر
The agricultural product in general and the agricultural product of the wheat crop in particular suffer from the fact that the price of their harvest is not keeping pace with the value of supplies production which generates a sense of unfairness on the one hand and weakens their purchasing power on the other, where this research was aimed at estimating the price of equity for the crop Wheat, which is considered to be one of the most important food crops. Research has also been aimed at keeping pace with the evolution of its prices to the development of the costs rural livelihoods, average per capita income in irrigation and value of plant production and plant production values on the other hand. The research on the data in the various numbers has relied on agricultural price statistics issued by the economic Affairs sector of the Ministry of Agriculture and Land reclamation. Descriptive and quantitative analysis was used in addition to the estimation of some standard models represented in the general time trend model in their simple linear form.
