Fortuna to foliar spray with potassium silicate (KSi), glycine betaine (GB)and their interaction treatments. The experiment was done in split-plot within complete block randomized design. Potassium silicate treatments were four concentrations as (0, 2, 4 and 6 g/l) and glycine betaine were three concentrations as (0, 2.5 and 5 g/l). The obtained results referred to that KSi and GB significantly affected on vegetative growth, chemical components in leaves, yield and quality. Furthermore, foliar application with KSi at 6 g/l gave the highest values of vegetative growth, leaves contents, yield and fruit quality. As well as, foliar application with GB at any concentration significantly improved vegetative growth, chemical components in leaves, yield and fruit quality compared to control. In general, the best interaction treatment in this concern was that KSi at 6 g/l interacted with GB at 5 g/l as foliar spray compared to the other ones under study. Thus, it can be recommended that spraying strawberry plants with potassium silicate at 6 g/l and glycine betaine at 5 g/l can promote vegetative growth and increase the early yield and fruit quality under cold condition that are likely to occur in this period (November to February) which meet main export season..</em>Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111220201201Influence of Proceeding Crop and Foliar-Applied Micronutrients on Faba Bean Productivity and Seed Quality1303130914980110.21608/jpp.2020.149801ENM.

Parents and their 21 F<sub>1</sub> crosses were evaluated under normal (continuous flooding) and water deficit (irrigation every 12 days) conditions during 2020 growing season,to estimate general (GCA) and specific (SCA) combining ability effects as well as identifying type of gene action controlling the inheritance of the studied traits.Both GCA and SCA mean squares were highly significant for all the studied traits under normal and stress conditions. The non-additive gene action played an important role in the inheritance of all the studied traits, except leaf rolling under stress treatment. The parents Sakha 107, NERICA 9 and N22 were the best general combiners for grain yield/plant. The crosses Sakha 107×Giza 177, Sakha 107×Fuknishiki, NERICA 9×Giza 177, NERICA 9×Akihikari, N22 ×IET1444, N22×Fuknishiki and IET1444 × Giza 177 were identified as promising specific combiners for improving grain yield/plant and one or more of its components under both conditions. The genetic diversity among the seven parental genotypes was assessed using ten Simple Sequence Repeats (SSR) markers. A total of 33 alleles were detected ranging from 2 to 5 with an average of 3.3 alleles per locus. The PIC values ranged from 0.32 to 0.69, with an average of 0.51.Genetic distance ranged from 0.24 to 0.92 with an average of 0.63. High genetic diversity was detected among the tested genotypes at the molecular level, hence these genotypes could be exploited to improve water deficit tolerance in rice breeding program.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111220201201Genetic Analysis of Chocolate Spot and Rust Disease Resistance and Some Yield Related traits in Three Faba Bean Crosses1333133914980510.21608/jpp.2020.149805ENSalwa M.MostafaFood Legumes Research Dep., Field Crops Research Institute, ARC, EgyptG.

The five populations (P<sub>1</sub>, P<sub>2</sub>, F<sub>1</sub>, F<sub>2</sub> and F<sub>3</sub>) of three faba bean crosses (Triple White x Ohishima Zairai), (Triple White x Giza 40) and (Triple White x Foul Sbaï labiade) were evaluated during 2019 /2020 winter season at Sakha Agricultural Research Station, to study the type of gene action for foliar diseases resistance and some yield related traits. Significant differences were found among generations, <em>i.e</em>. P<sub>1</sub>, P<sub>2</sub>, F<sub>1</sub>, F<sub>2</sub> and F<sub>3</sub> for the majority of studied traits of all crosses. Significant and highly significant desirable percentages of heterosis relative to mid and better parent with favorable values for inbreeding depression for most traits. Additive gene effects were positive and highly significant for chocolate spot disease reaction, rust disease reaction. However, the dominant gene effects seem to be controlling the inheritance of yield and yield component traits. Narrow-sense heritability ranged from medium to high in most cases due to the opposite directions of dominance and dominance x dominance effects. Genetic advance from selection ranged from 7.66% for flowering date to 45.65% for No. of pods plant<sup>-1</sup>in cross 3. Finally; it could be concluded that cross 2 and cross 3 were the best for flowering date, seed yield/plant and 100-seed weight, while cross 3 was the best in resistance to chocolate spot and rust diseases. Therefore, selection in the advanced generations of both crosses could be effective.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111220201201Influence of Foliar Application by Benzyladenine and Yeast Extract on Growth, Root Yield, Quality and Chemical Compositions of Sugar beet (Beta vulgaris L.)

The treatments were arranged in a complete block design in a split-split plot with three replications. Results revealed that increasing irrigation interval from 3 up to 7 days significantly reduced biochemical and physiological traits and root and sugar yields/fed. Soil application of zeolite achieved the highest values of all the parameters studied as compared to the untreated soil. Spraying beets with 1500 mg /l of nano-K gave the same trend of the recommended K-dose. Water use efficiency (WUE) for sugar yield increased with decreasing the amounts of applied irrigation water. Under conditions of the present work, adding 500 kg of zeolite/fed to the sandy soil, spraying beets with 1500 mg l<sup>-1 </sup>as nano-K fertilizer and irrigating the crop every 5 days using drip irrigation can be recommended to get the highest root and sugar yields as well as to save water and increasing water use efficiency.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111220201201Salicylic Acid Enhances Growth, Yield and Quality of Lettuce Plants (Lactuca sativa L.) under Drought Stress Conditions1581158614983110.21608/jpp.2020.149831ENS.

A field experiment was carried out during 2018-2019 and 2019-2020 seasons at the Experimental Farm, Faculty of Agriculture, Cairo University, Egypt. Drought was induced by withholding watering for 15 days after salicylic acid (SA) application exactly at 20 and 30 days after trasplanting. Five treatments were utilized. These were water-stressed +100 ppm of SA, water-stressed +200 ppm of SA, water-stressed +300 ppm of SA foliar spray, water-stressed only, and the fifth group served as control. Results indicated that water stress adversely affected growth and productivity parameters of lettuce cultivar “Big Bell”. Water stressed plants at earlier stage of growth (20 day stage) were more inhibitory as compared with the plants at the age of 30. Generally, foliar spraying with salicylic acid significantly protected against the stress and increased root length, root weight, fresh head weight, head diameter,photosynthetic pigments compared to treatment that under water deficit. However, proline content increased under drought as well as under SA treatments. Spraying of salicylic acid at 200 ppm at the age of 30 was the most effective treatment that causing significant increase in yield by18.31% and 26.9% relative to control treatment in the first and second seasons, respectively. Application with salicylic acid increases drought tolerance and avoids the deleterious effect of water stress.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-3669111220201201Inheritance of Stripe Rust Resistance in Adult Plants and Some Economic Traits of Some Bread Wheat Crosses1587159614790710.21608/jpp.2020.147907ENE.

The experimental design was split- split plot replicated three times. Results revealed that MW at all examined intervals gave the supreme significant increase on all studied growth parameters, herb fresh and dry yield/fed, essential oil percentage, oil yield/fed, photosynthetic pigments, carbohydrates, protein and productivity of irrigation water in the two cuts in both seasons. Appropriate irrigation interval (4 days) significantly increased herb fresh and dry yield/fed, essential oil percentage, oil yield/fed, those were higher in the 2<sup>nd</sup> cut than 1<sup>st</sup> one through both seasons while, a remarkable decrease in the 2<sup>nd</sup> cut was observed with nonMW. Spraying with SA at all levels in both water types significantly increased most of studied attributes particularly at 150ppm. It could be concluded that MW every 4 days interacted with 150ppm SA were effectively increased growth, yield, oil %, oil yield, major components linalool and 1, 8- cineol, certain metabolic characters. Consequently MW irrigation every 4days with spraying 50ppm SA on basil under salt stress and definite water sources could be recommended for enhancing growth, qualitatively and quantitatively oil yield.
