Stability Analysis of Yield and Its Components for Promising Barley Genotypes under Water Stress and Saline Affected Fields
EL SAYED
EL-Shawy,
The objective of this investigation aim was to evaluate twenty barley genotypes under different environments for testing stability of their performance. Where, development of any crop genotypes with adaptation to changes is one of most important goal of breeding program. This study examined twenty barley genotypes over different three environments; normal, water stress and salt stress. The normal and water stress experiments were conducted at Sakha while salt stress experiment was conducted at the El-Hosinia station during two seasons (2014/2015 and 2015/2016). The combined analysis of variance for environments, genotypes and (Genotypes x Environments) interaction was highly significant for all studied genotypes, suggesting differential responses of the genotypes and the need to stability analysis. Results revealed that highly yielding genotypes can also be stable. Giza 133 and Line 7 had desired performance (grain yield) compared to the grand mean, regression coefficient (bi) did not differ significantly from unity and had low deviation from regression (S2d) values, indicating the role of linear portion of G x E interaction in the performance of these genotypes. Giza 130, Line 4, Line 5 and Line 8 had the lowest (bi) values which were more adapted to unfavorable environments, whereas Giza 132, Line 3 and Line 6 were input sensitive and adapted to high potential environments.

Studies on Japonica Hybrid Rice Seed Production under Egyptian Conditions
M.
Selim
Two- experiments were conducted at Sakha Experimental Farm of Sakha Agricultural Research station, Kaferelsheikh, Egypt during 2016 and 2017 rice growing seasons. The objective of this investigation was to study the effect of three Male(P):Female(S) rows ratio (2P:6S, 2P:8S and 2P:10S) and two pollen directions of the pollen parental line (P), one direction and two directions on out-crossing rate for Japonica hybrid rice seed production. Japonica hybrid produce through crossed between one Thermo-sensitive Genic Male Sterile (TGMS) line (TG-60-6) as a female line (S) with Sakha105 which used as a male pollinator line (P). A split-plot design with three replications was used. The main plots were dedicated to rows ratio whereas direction of the pollen parental line was arranged within the sub plots. The results notify that the better row ratio was 2P:6S gave the best seed yield hill-1 (25.00 and 27.38 g) in 2016 and 2017 seasons respectively. For direction of the pollen parental line, the best F1 seed yield hill-1 (25.89 and 27.45 g) were obtained once planted the spore parental line in two directions during 2016 and 2017 seasons, respectively. The interaction between row ratio and direction of the pollen parental line was highly significant for panicle weight (g), seed set (%), number of fertile panicles hill-1, harvest index (%), and seed yield hill-1, but not significant for plant height (cm) and panicle length (cm) during 2016 and 2017 seasons. The results notify the importance of optimum row ratio and direction planted of pollen parental line for increasing the out-crossing rate in Japonica hybrid seed

Estimation of Genetic Components and Heritability for Fruits Yield and Quality Characters in Tomato (Solanum Lycopersicom)
M.
ELnager
Six parental genotypes of tomato (Solanum Lycopersicom), i.e. Castel ruck (p1), Imperial (p2), Crystal (p3), Perso (p4), Pascal (p5) and Valcum valentime (p6) were crossed in a half diallel fashion to produce F1 in order to study some genetic components and ratios for some economic traits. The study consisted of twenty one genotypes; these genotypes were six inbred lines (parents) and fifteen F1 crosses. These twenty one genotypes were subjected to evaluation trial at Moshtohor village, Kalyobiya Governorate, Egypt during summer seasons of 2016 in a randomized complete block design with three replications. Data on yield and its components and fruit traits were recorded and subjected to statistical analysis to investigate Hayman's approach were used to study genetic components and heritability which control these traits. Data indicated that the additive component (D) was insignificant for average fruit weight, number of fruits and total yield per plant traits indicating the importance of non-additive effect in the inheritance of these traits. Meanwhile, the dominance genetic variations H1 and H2 were significant or highly significant for all studied fruits traits, showing the importance of dominance genetic effects in the inheritance of these traits. The average degree of dominance (H1/D) ½ showed over dominance for the average fruit weight, number of fruits and fruit yield per plant traits. The proportion of gene with positive and negative effects (H2/4H1) in the parents was lower than one quarter proportion, indicating unequal distribution between the positive and negative alleles among the parents. The ratio of dominant to recessive alleles (KD/KR) in the parents was more than (one), indicating that the six parents used in the present study carried more dominant than recessive allels. Heritability estimates in broad sense are very high for average fruit weight trait (100%), number of fruits (96%) and fruit yield per plant (92%), indicating the importance of genetic components of variation in the inheritance of these traits encouraging the usage of breeding programs to improve these traits. Meanwhile heritability estimates in narrow sense was low (2.7%, 1.4% and 0.7 %, respectively) clarifying the importance of non-additive genetic effects in the inheritance of these traits. These results indicate that a major of total phenotypic variances due to dominance and/or over-dominance and the environmental factor affects the inheritance of these traits. So it is of great importance to develop new hybrids in order to obtain maximum fruits number.

Effect of Different Substrates with Organic and Inorganic Fertilization under Closed System Condition on Lettuce Production
Fahima
Fahima H. Ayoub
Growing medium and fertilization are the most effective methods for controlling and improving the vegetative growth characteristics, head quality, yield and nutritional value of lettuce. Therefore the aim of this study was to determine the effect of different growing media when using organic or inorganic fertilization that associated with closed system on lettuce production in soilless culture system. Planting was conducted on A- shape system under unheated plastic greenhouse conditions. Experimental treatments included two nutrient solutions (mineral nutrient and compost tea) and seven substrates i.e. Peat moss, Perlite, Coir, Rice straw, Compost, Peat moss + Perlite (1:1 v:v) and Coir + Perlite (1:1 v:v). Results revealed that mineral fertilizer had better mean values for all measured vegetative growth parameters, total yield, NPK and chlorophyll content compared with organic fertilizer. The best vegetative growth characters in terms of leaf length, width, and area, number of leaves, head firmness, surround and weight, total yield, NPK and chlorophyll contents were occurred 100 % in coir or peat. The most favorable beneficial interaction treatments regarding the previous growth characters were produced in plants which planted in coir or peat moss with mineral fertilizers. The results indicated that lettuce plants on the peat moss substrate with organic solution grew healthier, but the heads were small and the yield was decreased compared with the inorganic solution. The study revealed that, differences in nutrient fertilizers and growing substrates were significant and their influences have affected the growth and yield of lettuce when cultivated under controlled environment. This study showed that mineral fertilizer had better mean values for all measured growth parameters. While, peat moss and coir substrates proved to be the best growing for lettuce. This growing media enable the roots to develop better. Thus paving the way for plants to absorb more nutrients than the plants grown in other different substrates.

Effect of Nutrition and Pruning Methods on Productivity and Quality of Cucumber Hybrids in Greenhouse
M.
ELnager
Two experiments were carried out on cucumber (Cucumis sativus. L) under greenhouses conditions at Kaha Research Farm, Hort. Res. Inst., ARC, Egypt during successive spring seasons of 2014 and 2015 to compare the effect of NPK fertigation rates and some pruning types on the fruit quality, yield, and minerals contents of some cucumber hybrids grown under plastic greenhouse conditions. The investigation consisted of three fertilization levels i.e. 75%, 100% and 125% from the recommended dose of NPK fertilizers, two pruning methods (one shoot and two shoots/plant) and two cucumber F1 hybrids i.e. Sina 1 and Sina 2 were used. The results indicated that cultivar Sina 2was the best comparing with the Sina1 concerning yield and fruit characteristics, fruit mineral contents (nitrogen, phosphorus and potassium), ascorbic acid and total sugars. Similar results were obtained by using pruning plants on one branch per plant. Using 125% from the recommended doses of NPK fertilizers gave the highest values of yield and different fruit characteristics, fruit mineral contents (nitrogen, phosphorus and potassium), ascorbic acid and total sugars content compared with the other treatments. The highest values for fruit characteristics N,P,K, TSS, and V.C content in cucumber fruits were obtained from the interaction treatment between cv. Sina1, pruning the plant on one branch and fertilizing with 125% from the recommended dose of NPK fertilization level.

A.
Shams
Ten parental lines were crossed in a line x tester (7L x 3T) mating design in the summer season of 2016 to obtain 21 F1 hybrids to study the genetic behavior of some economic traits for cultivars of summer squash crop suitable for Egyptian cultivation. In 2017 summer season, the ten parents and their 21 F1 hybrids were evaluated with four commercial checks "Aziad, Adronto, Marselia and Tabark" in the experimental design which was a randomized complete blocks with three replications at Kaha Research Farm of Vegetables Breeding Department, Horticultural Research Institute, (HRI), Agric. Res. Center (ARC) in the Kalyobiya Governorate. Data indicated that fifteen and ten crosses had highly significant values of heterosis over the mid-parents and the better parents, respectively for number of fruits/plant trrait. Concerning heterosis over the checks hybrids, four and two crosses showed significant and highly significant values of heterosis over hybrid Aziad and Tabark, respectively but only one crosses (P7xP10) showed highly significant positive values over the checks cultivars Adronto and Marselia. Meanwhile, all crosses showed insignificant values of heterosis over the mid-parents and the better parent concerning yield /plant trait. Heterosis over the checks hybrids, three, zero, once and once crosses gave significant or highly significant positive values of heterosis over Aziad, Adronto, Marselia and Tabark, respectively. Two lines and two testers gave significant or highly significant positive values of gca effects on number of fruits/plant trait. Also, three lines showed significant or highly significant positive values of gca effects on yield /plant trait. Therefore, these lines considered good combiners for yield traits. In concern of sca effects, three crosses out of twenty ones gave significant or highly significant positive values for total yield plant trait.

M.
ELnager
Two field experiments were carried out during the two successive summer seasons of 2016 and 2017 at the vegetable farm of the faculty of Agriculture Moshtohor, Benha University, Egypt to investigate the response of Squash plant Cv. Eskandrani to mineral, organic and bio fertilization on fruit yield and its components as well as fruit quality. The experimental treatments of mineral, organic and bio fertilization in single or combined application were conducted as follows:-100% mineral nitrogen fertilizer from recommend dose (200kg ammonium nitrate per feddan), 75% mineral nitrogen plus 25% organic manure in the form of compost, 50% mineral nitrogen plus 50% organic manure, 25% mineral nitrogen plus 75% organic manure, 100% organic manure (compost), 100% organic manure (compost) plus addition of phosphorine at rate of 500 g/fed plus Nitrobein bio- fertilizer at rate of 400g/fed.. Obtained results showed that,There were a significant differences among the studied nitrogen fertilizer treatments on all determined yield and its components and fruit quality during the two seasons of growth. In this concern, fertilizing squash plants with 100% mineral nitrogen fertilizer only reflected the highest values of number of fruit per plant, fruit yield per plant and total fruit yield per feddan compared with other nitrogen fertilizer treatments. The highest values of fruit length, diameter and weight were recorded from 100% mineral nitrogen of recommended dose, followed by 100% organic manure treatments, followed by 75% mineral nitrogen plus 25% organic manure.

Efficiency of Some Bioagents and Potassium Humate in Controlling Tomato wilt Disease caused by Fusarium Oxysporum f.sp. Lycopersici
Mona
Ahmed
Fusarium oxysporum f.sp. lycopersici (FOL) is one of the most important fungi causing vascular wilt disease of tomato plants. Many different agents i.e., Bacillus subtilis, Trichoderma harzianum, T. viride, alga (Sparulina platensis), Mycorrhiza (Glomus sp.) and potassium humate were investigated for their antagonistic effects on the growth of FOL in vitro. T. harzianum and potassium humate were the most effective treatments, followed by B. subtilis and alga extract. The previously mentioned treatments were studied under greenhouse conditions and natural infection in the field. T. harzianum and potassium humate were the most effective treatments against FOL followed by B. subtilis and alga extract. Mycrrohiza was the lowest effect treatment under greenhouse and field conditions. T. harzianum and potassium humate decreased the activities of hydrolyzing enzymes and increased all of total phenols and plant parameters (fresh, dry weight and length/ plant) of treated tomato plants.
